Ridomil is a powerful fungicide against fungal diseases of horticultural crops, which cause the greatest plant depletion and yield losses. Produced by Syngenta Crop Protection (Switzerland). The active ingredients are mancozeb from the dithiocarbamate class (640 g / kg dry matter) and phenylamide mefenoxam (40 g / kg dry matter), see fig .:

Advantages and disadvantages

The advantages of the drug Ridomil are as follows:

• Gives a quick healing effect, incl. from neglected diseases.
• The drug Ridomil allows you to completely destroy pathogenic fungi in plants and thereby quickly, without further relapses, eliminate the focus of their infection in the area, both old and newly emerged.
• Practically does not cause resistance (resistance to the drug) in objects of elimination.
• Gives a healing effect in plant parts not treated with the drug.
• The preparation of the working solution (see below) does not require a particularly precise dosage.
• The effectiveness of Ridomil does not depend on the cultivation conditions of the treated plants: the use of the drug is carried out according to standard regulations and schemes (also see below).
• Storage of Ridomil, in addition to the usual precautions (under constipation, inaccessible to children and animals in a room separate from the food storage store), does not require additional safety measures: the drug is not flammable, volatile, not explosive. Storage temperature range from –10% to +35 degrees Celsius.
• The effectiveness of the drug in an unopened package does not decrease throughout the entire shelf life. Almost branded Ridomil in its original packaging, after 5 years of storage in an unheated dacha, acts like a fresh one.

However, the fungicide Ridomil is not devoid of serious disadvantages:

1. The drug is toxic: hazard class 2 for humans (hazardous substance); for bees - 3rd (summer limit 24 hours, apiary protection zone 3 km).
2. The range of action of Ridomil is very limited; however, the diseases against which it is effective (see below) cause the greatest depletion of plants and loss of yield.
3. The price of Ridomil and the consumption of the drug per unit of the treated area are quite high.
4. Ridomil is not stored in an unopened container: an opened package should be used immediately and completely.
5. Ridomil, along with pathogenic fungi, destroys useful soil fungi, therefore, its regular use and / or overdose worsens the quality of the soil. Accelerated reclamation of the land poisoned by Ridomil with improvised means is impossible.
6. The introduction of compost, humus and other household biological agents into the soil to increase its fertility in the areas where Ridomil is used is useless.
7. Fungicide Ridomil is able to accumulate in fruits and soil and give long-term negative effects, similar to other carbamate-based products.
8. Ridomil, contrary to advertising claims, is weakly phytotoxic (it slightly inhibits the growth and development of plants). This is a common property of many pesticides, but in the event of an overdose or violation of the processing schedule (tightening of the schedule of spraying exits), the phytotoxicity of Ridomil increases sharply.

Note: the last point among amateur growers who have personal experience in handling Ridomil can cause at first glance reasonable objections. But - see further in a special section.

Indications for use

Since Ridomil is quite highly toxic, and due to the above features of the drug, the use of the fungicide Ridomil and its modifications (see below) is justified, firstly, at a weekend cottage, which is an essential food or commodity support for the owner's family. Secondly, in the event of a sudden massive outbreak of a drug-treatable disease.

The drug Ridomil is most effective against such devastating diseases of the most important and important food crops as (see fig.):

• alternaria and, to a slightly lesser extent, fusarium of potatoes;
• alternaria and, slightly weaker, late blight of tomatoes;
• peronosporosis of cucumbers and onions (for onions on a feather and other green crops, treatment with Ridomil is unacceptable!);
• mildew (downy mildew) of grapes.

The use of Ridomil on nightshades is especially effective. Even on a new, heavily infected with a pathogenic fungus, yield losses, compared with a planting sterile for this pathogen, do not exceed 5-7%, which is no more than fluctuations in yield from weather and uneven soil quality. Improper use of the drug can cause greater damage. How Ridomil works on tomatoes, see the video below:

Video: Ridomil and tomatoes

With regard to the use of Ridomil in the vineyard, then, firstly, oidium is the same scourge of grapes. The symptoms of both diseases are similar, but Ridomil from oidium is ineffective. Secondly, growing grapes in a weekend dacha is of little use - they will be wrapped, it is very tempting and affordable. And it is possible to cope with mildew in the initial stages of a lesion in an area under supervision with less dangerous means. Thirdly, there is no panacea for grape diseases and is not expected; you need to keep your vineyard healthy using complex remedies, and to prevent / treat a specific disease, alternate drugs on a different chemical basis, see, for example. track. rollers:

Video: overview of fungicides for grapes

The reason for the effectiveness of dithiocarbamates as fungicides, firstly, is that each such complex is a pair of carbamate "mites" that "grabbed" the ions of various metals, which makes it difficult for pathogens to develop resistance to the agent. And the high content of active sulfur further increases the fungicidal activity. Sulfur is generally a powerful remedy against fungi; let's remember about colloidal (finely dispersed) sulfur.

In general, Ridomil also acts in a comprehensive manner. Mancozeb is a water-insoluble contact fungicide; it forms a dense, resistant film on the treated plant surface. Mefenoxam, on the contrary, is easily soluble and quickly, in 2-3 hours, completely diffuses (seeps) into plant tissues. The translaminar activity of mefenoxam is high both in the acropetal (from bottom to top, from the roots to the vegetative and generative organs) and in the reverse basipetal direction. As a result, mefenoxam permeates the entire plant, including young shoots, leaves and buds. This component of the drug destroys young, not ready for sporulation, mycelial cords (hyphae) of fungi located deep in plant tissues and inaccessible to other means. As a result, the plant is completely healed, and the persistent film of mancoceb on the leaves and stem prevents re-infection. Since the life cycle of pathogenic fungi is several times shorter than the growing season of plants, the use of Ridomil makes it possible to completely eliminate the focus of fungal disease on the site within one season.

Note: the selective action of Ridomil is not due to its focus on the physiological mechanism of the objects of elimination, but to the peculiarities of their development in the host plant. Therefore, Ridomil is also killer for beneficial fungi-antagonists of pathogens.

Release forms and analogues

Fungicide Ridomil for small areas is available in granular forms Ridomil Gold and Ridomil Gold MC. Granulation is carried out according to the PEPIT technology patented by the manufacturer, according to which dense, dust-free beige grains are formed, completely dispersing in water in less than 1 minute. As a result, the preparation of a working solution of the drug requires elementary precautions: latex gloves on the hands, glasses on the face and a gauze bandage. But work with Ridomil at the site must be carried out in full compliance with the safety rules for substances of the 2nd hazard class, see below!

Compositionally analogous to Ridomil are fungicides Tyler, Tragon, Fungicide Gold-M (what kind of marketer came up with the name?), Healer and Juncker, produced in neighboring countries. But (remember, it will still come in handy, see below), the only registrant of Ridomil in the Russian Federation is Syngenta Crop Protection and they are not yet selling a license for PEPIT. Therefore, firstly, it is necessary to work with analogues of Ridomil at all stages of use as with substances of the 2nd hazard class, no matter what is written on the packaging. Secondly, Syngenta does not guarantee the purity of analog components and the quality of their manufacture.

About fakes

Due to the effectiveness of Ridomil in especially severe emergencies, there are a lot of no analogues on the market, but outright falsifications of the drug. There is no need to be guided by the original in terms of price: roguish artisanal manufacturers know consumer psychology very well and often pay a price higher than the real one for the "palette". It is also impossible to open unpaid packaging and examine whether the granules are loose or dusty at the point of sale. The first way to distinguish an original from a fake is by the manufacturer's trademark. Its exact appearance, colors and proportions are shown in the figure .. Recall that the only registrant of Ridomil in the Russian Federation is Syngenta Crop Protection, and they have not yet sold licenses for this drug. Outright theft of a corporate logo in Russia is punishable enough severely, and Switzerland is not a state with which anyone in their right mind would take liberties. Therefore, counterfeiters either tear apart the Syngenta logo, or distort it, or do not put it at all. So, if this sign is not on Ridomil's bag, or it is somehow different, do not take it.

The second, effective for the products of a number of completely reckless foreign manufacturers, is in packaging. Ridomil for large areas is produced by Syngenta only in boxes of 1 and 5 kg, and Ridomil Gold and Ridomil Gold MC in vacuumed sachets of 25 and 50 g. The original preparation is weighed exactly; packaging (bag) weighs approx. 1.2 and 1.6 g respectively Place the bag on a precision balance (electronic ex.); if the weight "disperses" - do not take this / here. And if the weight is indicated on the package, say, 20 g, then this is definitely either "singed", or not the best of the analogues, see the video:

Myths about Ridomil

A good portion of the materials on Ridomil on the Runet were written by the authors, some of whom give the impression that, forgive me, they do not understand which end of the shovel should be dug. They rewrite firm manuals in good faith, but, firstly, without delving into the meaning. Secondly, only the main part, and notes, explanations and additional materials with the results of independent research for the sake of "accessibility" of the text are simply ignored. As a result, about Ridomil there are a number of incorrect statements:

• Ridomil is a prophylactic drug. In fact, he is a typical ambulance, powerful but dangerous. Preventive spraying with Ridomil is carried out only on infected areas, where acc. the incidence of plants (see above) is repeated from year to year. After the site is rehabilitated, treatment with Ridomil is stopped, especially since carbamates require alternation with pesticides on a different chemical basis. If the focus of the disease has arisen suddenly in a healthy area, the frequency of treatments is reduced by 1 (see below).
• It is easy to process plants with Ridomil. On the contrary, see below. The simplicity of the application regulations by no means means the technical simplicity of the work.
• Ridomil helps with almost all fungal rot. No more other less dangerous dithiocarbamates. Ridomil is a specialized drug. "Universal", but even more dangerous means of ambulance in severe cases of damage to vegetative parts of plants by fungi pathogens - Fundazol.
• Ridomil can be used for fruit rot. No and no again. Mefenoxam easily penetrates into fruits and accumulates in them. A means to protect the crop from scab, moniliosis, etc. - Horus.
• Ridomil can be used for flowers and indoor plants. Absolutely not. After approx. After 10 days, the mancozeb film on the plants begins to disintegrate and the substance of the 2nd hazard class appears in the air.

Is Ridomil a stimulant?

The property of Ridomil supposedly to stimulate plant growth should be said especially, because it is declared in some manuals of rather serious suppliers. At first glance, the reasoning is convincing: look, the grapes were sprinkled with Ridomil from mildew, and the bush grows better than the healthy one in the next row.

This is an impure experience. The visible powdery mildew on grapes is a mature mycelium with sporangia of the causative agent of the disease - the imperfect fungus Plasmopara viticola (Uncinula necator (\u003d Oidium tuckeri) on Wikipedia - incorrect) A "healthy" bush nearby is also affected; mildew is no less infectious to grapes than the plague is to humans. It has already been penetrated by young mycelial strands of the pathogen, and therefore it grows worse than sterile. Healed better than the patient in the latent phase of the disease, but still worse than the really healthy one.

Note: absolutely all pesticides inhibit plants to one degree or another. It's just that without them, the lag in development and crop losses will be even greater.

Precautions

Mefenoxam penetrates into the human body as easily as into any other humid environment. Therefore, you need to work with Ridomil in a full set of PPE, see Fig., And in a respirator with gas cartridges. Since such a kit is by no means cheap, in the case when it is necessary to cope with a sudden outbreak of the disease, it is better to call a specialist for treatment.

Ridomil suppresses healthy plants more than sick ones, and also destroys useful fungi. Therefore, the precautions for plants when processing with this preparation are as follows:

1. Solid plantings can be sprayed with winds up to 4-5 m / s (leaves on trees begin to flutter a little; thin branches sometimes sway);
2. A shingle in a small area is treated only in calmness, preventing the drug from getting into neighboring healthy plantings;
3. The treatment is carried out from a sprayer giving a misty stream until a continuous film of the solution forms on the plants. The dripping of solution drops onto the soil is unacceptable! Therefore, the following rates of consumption of the working solution are relative - the processing process must be carefully monitored visually.

In any case, the security belts of the work area with Ridomil are as follows:

• non-residential buildings - 15 m;
• helpers and other healthy people - 15 m to the wind from the jet;
• residential buildings, children's facilities, reservoirs, water supply sources - 50 m;
• for children, allergy sufferers, cancer patients or those who have been ill, pregnant women, nursing mothers - 50 m;
• apiary - 3 km (limitation of summer bees from 24 hours).

Note: there are no obvious primary symptoms of Ridomil poisoning. In case of any deterioration in health, you should immediately stop working and consult a toxicologist.

Compatibility

Ridomil in tank solution is compatible with most pesticides. But due to the complex composition of the drug, the manufacturer does not provide a list of agents compatible with it, especially since the range of pesticides on sale is changing. For the same reason (complex composition), checking the compatibility of Ridomil with improvised means at home does not always give an unambiguous result. If the compatibility is precisely established (for example, by consulting on the company's website or with a specialist), then the dissolution of substances in the tank (see below) is made necessarily in the next. order: water-soluble agents (VRK, VRP, VRG)\u003e SP (wettable powder)\u003e RIDOMIL GOLD MC, VDG\u003e KS (concentrated suspension; sometimes referred to as SC on foreign products)\u003e EC.

Note: VRK - water-soluble concentrate; VRP - water-soluble powder; VRG - water-soluble granules; VDG - water-dispersed granules; CE is a concentrated emulsion.

Preparation of working solution

To work with Ridomil, a sprayer with a built-in or separate submersible electric (mechanical) agitator is required. You cannot prepare the mother liquor, pour it from the tank and shake it with your hands! Ridomil's working solution (possibly in a mixture, see above) is prepared as follows:

1. the sprayer tank is half full;
2. include a stirrer;
3. open the package of the drug;
4. in a thin stream, the drug or components of the mixture are introduced into the tank in the desired sequence (see above);
5. with a thin stream, without turning off the mixer, add water to the norm;
6. interfere for another 2-3 minutes (more, if necessary for other components of the mixture);
7. close the tank and immediately start work;
8. the solution should be consumed in no more than 3 hours (the permissible time for working with Ridomil is 4 hours).

Application procedure

Ridomil is used in the form of a 0.5% solution, i.e. a bag of 25 g for a 5 l tank; packing 50 g per 10 l. Instructions for using Ridomil are given in the table:

Processing, if it is cool or moderately warm, should preferably be carried out in the morning, so that the increased sap flow during the day helps mefenoxam spread. But in no case due to dew, the "internal" component of the drug will be washed off. The same will happen when spraying in foggy weather or less than 3 hours before rain. In the heat, on the contrary, it is better to spray in the evening (highly desirable in cloudy weather), so that the increased transpiration of plants in the light does not interfere with mefenoxam spreading in them. The precautions for plants when processing them with Ridomil are mentioned above. In the period from the beginning of budding to the formation of ovaries, the use of Ridomil should be stopped, i.e. application regulations must be consistent with the timing of flowering plants. An exception is potatoes, because its aerial parts are inedible, and tubers are not modified vegetative parts like bulbs.

Finally

Finally, we repeat the most harmful of the myths scattered above: Ridomil is by no means a prophylactic agent for systematic use. This drug is used to eradicate pathogenic fungi in an infected area or, in the event of a sudden mass destruction of plantings, when the first signs of the disease appear. In any case, the effectiveness of Ridomil will be greatly enhanced by the so-called. curative fungicides (the same for example). They deprive pathogens of the ability to sporulate, suppress their vital activity and resistance to Ridomil. Plantings are treated with curative once when the first signs of the disease appear. Then they go to Ridomil. A wedge is knocked out like a wedge: two dangerous and toxic drugs rid the area of \u200b\u200bpathogens, and from next season you can use less harmful fungicides or even switch to safe biologicals.

Ridomil Gold MC, water-dispersible granules - a two-component combined preventive action fungicide to protect grapes, potatoes and vegetables from a complex of diseases. The preparation contains two active ingredients: mancozeb 640 g / kg - contact action, and mefenoxam (R-isomer of metalaxyl) 40 g / kg - systemic action.

The combination of substances with different mechanisms of action effectively protects plants from pathogens and reduces the risk of developing resistance.

Instructions for the use of fungicide Ridomil Gold MC:

• used on onions and cucumbers against peronosporosis
• on grapes from mildew
• on potatoes and tomatoes against late blight and alternaria

The period of protective action is 7-14 days. It is not recommended to use a pesticide as an eradication or treatment agent, Ridomil Gold should be used prophylactically, that is, before plant infection!

Ridomil Gold MC application rates:

• On grapes and cucumbers 25-30 grams per 10 liters of water - no more than 4 treatments per season.
• On potatoes, onions, tomatoes - up to 50 grams per 10 liters of water - no more than 3 treatments per season.

Waiting time before harvest:

• Grapes - 21 days
• Potatoes, onions per feather - 15 days
• Open field tomatoes - 10 days
• Open field cucumber - 5 days

Compatibility with other pesticides and fertilizers:

Ridomil Gold MC is in most cases compatible in tank mixes with insecticides and agrochemicals, with the exception of solutions with an alkaline reaction.

Phytotoxicity:

Hazard class and application:

At present, it is prohibited to use Ridomil Gold MC in personal household plots! Hazard class for humans - 2, for bees - 3. It is prohibited to use the drug without the use of personal protective equipment!

The practice of using the drug Ridomil Gold MC on grapes:

Ridomil Gold is deservedly one of the most popular means of protecting vineyards from mildew. Practice shows that one preventive treatment is guaranteed to protect the grapes for at least two weeks, and even longer if the infectious background is low. Today this preparation is an indispensable and reliable component in amateur vineyard protection schemes. The first treatment with Ridomil Gold is carried out before flowering. Long-term action will provide protection for flowers and young ovary, even in case of prolonged flowering and adverse weather conditions. The second spraying after flowering, at the stage of a match-head berry, the third - two weeks after the second. It is not advisable to use Ridomil Gold later because of the rather long waiting period.

Currently, in retail sales, in small packaging, there are a lot of fakes of popular pesticides. The photo shows the original view of the granules of the drug Ridomil Gold:

Manufacturer: Syngenta Packing: 1kg and 5kg plastic canisters. Shelf life in original packaging: 3 years. Storage conditions: at an air temperature from -10C to + 35C in a dry room, in unopened original packaging.

In order for the grapes to bear fruit well, they need to be watered, pruned and processed. Fungal diseases are a common problem for vines. They spoil wood and ripening clusters. The use of the drug Ridomil Gold creates reliable protection for grapes against fungal infection. But experts recommend working with the tool carefully, strictly observing safety measures and not violating the dosage.

Ridomil Gold: useful properties

The agent in question is included in the group of antifungal drugs for systemic contact effects. The manufacturer produces Ridomil Gold in powder and granule form, which contain two active ingredients:

• Mancozeb (concentration 64%).
• Metalaxil (8%).

Substances penetrate into the plant and protect all its parts from roots to berries. They settle on the surface of the green mass. Strengthens the vine's immunity to fungal diseases. The drug demonstrates high therapeutic and prophylactic properties in relation to mildew. It does not affect the causative agents of powdery mildew.

Advantages and disadvantages of Ridomil Gold

Reading reviews of agronomists about the drug Ridomil Gold, novice gardeners will certainly pay attention to the possibility of its use for therapeutic and prophylactic purposes in the early stages of grape infection with a mycotic infection.

Other advantages of the drug are:

• Lack of phytotoxicity;
• Bilateral protection of bushes from infection;
• The ability to protect the root system;
• The speed of penetration into the vine;
• Ease of use - thanks to the PEPIT technology, the granules dissolve in water in just 1 minute. The risk of accidental inhalation of the fungicide is minimal as the granules are dense and large in size;
• Convenience of storage - the substance does not lose its useful properties at temperatures from -10 to + 35 ° C;
• The ability to protect onions, potatoes and other vegetables from diseases;
• The presence of analogues - Tragon, Tyler, Juncker, Healer.

The disadvantages of the product include high toxicity to humans, animals and fish, wasteful consumption and environmental damage. But if you use the fungicide wisely, the trouble will bypass the gardener.

How to use Ridomil Gold for grapes

Before spraying the plantation, check the sprayer - it should not contain residues of other preparations. The Ridomil Gold solution is made for grapes according to the instructions for use, focusing on the ratio of 25 g of substance to 10 liters of water. If there are few plants, the dose is reduced to 10 g of the drug and 4 liters of liquid.

Spray the grapes with a fungicidal agent immediately after preparation. The work is performed in the morning in dry weather. Hold the sprayer towards the wind to avoid inhaling the chemical. Ripe clusters are cut 2 to 3 weeks after the garden was last sprayed.

How often can grapes be sprayed against fungus with Ridomil Gold:

The consumption of the drug is 100 - 150 ml / sq.m. They don't do it with a margin. Always prepare a fresh solution. The grapes are sprayed in a special suit, gloves and a mask.

If it suddenly rains the next day, the grapes do not need to be sprinkled again. Metaloxyl on the leaf surface instantly transforms into a protective film that is not afraid of moisture. Mancozeb is inside the structure of the bush half an hour after the procedure.

It is impossible to mix and use Ridomil Gold with other antifungal and insecticidal agents if they give an alkaline reaction. If it is necessary to use neutral substances, carefully study their instructions for compatibility.

The second class of toxicity of the fungicidal preparation warns of the danger of granules for humans and fish. There are no consequences for birds and bees. To avoid environmental pollution, do not spray the solution near open reservoirs and fish farms.

Storage conditions

Ridomil Gold powder and granules are not afraid of low temperatures. But packages cannot be stored in the yard; it is better to place them indoors. Moisture should not penetrate into the opened bag, otherwise the substance will be taken in lumps and lose some of its useful properties.

The drug is not flammable. Therefore, you do not need to worry about fire safety. Powder and granules retain their fungicidal qualities if stored properly for 3 years from the date of release.

The product is sold on the website of the official manufacturer "Syngenta" and in specialized stores. The price of 1 kg of powder is 10-15 dollars. You can buy the drug wholesale and retail. The manufacturer positions its product as a prophylactic agent, however, many summer residents have already become convinced that Ridomil Gold is the best medicine for grapes for fungal diseases.

In the fight against many fungal diseases that affect vegetable and fruit crops, fungicides are used. The most popular, the best and most effective of them is the biological agent Ridomil Gold. It has simple and straightforward instructions for use. It dissolves quickly in water and is used for spraying plants. However, you need to buy the drug only in a specialized store, since there is a large list and percentage of fakes in the markets. Using Ridomil Gold, you must adhere to the dosage and recommendations, as well as observe safety measures.

Consider the description of the drug. Ridomil Gold MC, EDG contains metalaxyl, mancozeb and is effective in the fight against various fungal diseases, as it protects the vegetative parts of the plant, that is, leaves and stems. In addition, it has a positive effect on fruits, tubers and berries. It is used to combat powdery mildew, rust, mildew and many other diseases of vegetables, fruits, berries and flowers. It decomposes quickly in the soil, protecting the plant inside and out.

Instructions for using the fungicide in the garden

Fungicide Rodomil Gold MC, VDG has a minimum packaging of 25 and 50 grams, and for wholesale buyers from one kilogram.

Before diluting the product in water, make sure that the spray container is clean, free from residues of other chemical solutions. The dosage of the chemical is 25 grams per 10 liters of water, which must be completely dissolved according to the recipe. The working composition is prepared strictly before use, since over time it loses its properties. Two weeks after systemic treatment, you can harvest. Consumption of the solution is on average 300-400 liters per hectare of garden; it takes twice as much to process the vineyard.

For vegetable crops

When Rodoml Gold MC, EDG is used to treat cucumbers or tomatoes for diseases, then the work is carried out in the evening or early in the morning and only in calm weather. This will help prevent the chemical from spilling onto neighboring crops. It is used not only in the treatment of fungal diseases, but also for the prevention of ailments. If the disease has already begun to affect vegetable crops, then first a defense system is used - any curative fungicide, for example, Cabrio Top, and after a week, treatment is carried out using Rodomil Gold or Falcon. After another week, the plants are treated with contact fungicides. Spray vegetables correctly and in sufficient quantity so that the leaf surface is completely moistened with the solution. For these purposes, a spray bottle is used, which will not allow the preparation to drain from the leaves. When the composition is completely dry, it will not be washed off by rain. After preparation, the working mixture should be homogeneous and used within a maximum of three hours after preparation.

Treatment of grapes with a preparation

For the prevention of grape diseases, such as mildew or rust, a solution is prepared. The rate for 10 liters of water is 25 grams of powder. In more rare cases, a concentration of 50 grams of the composition per 10 liters of water is permissible. On average, this amount is enough for one hundred square meters of vineyard. Spraying is carried out only in dry, calm weather. During work, the wetting of leaves, stems and fruits should be uniform.

For the prevention of grape diseases and their treatment, spraying is carried out according to the calendar during the active growing season, as well as before the appearance of the first four leaves. 7 to 10 days should elapse between treatments. The last time the grapes are sprayed with Horus is 14 days after flowering. The finished solution is used during the day, preferably immediately after preparation. A good time for work is evening or morning. It is impossible to mix Rodomil Gold with other drugs; it is allowed to alternate spraying with other chemicals from the fungicide group, for example, with Tiovit Jet.

Preventive spraying of potatoes

For preventive purposes, potatoes are sprayed with a diluted drug Ridomil Gold. Since it contains the substance mefenoxam, the plant is protected from the inside. This action is explained by the fact that it is able to penetrate into the structure of the tops. Mancozeb fights the fungi, which kills it outside. These substances are the most important in the fight against diseases of vegetable crops.

After spraying the chemical on potatoes, the protective and prophylactic activity remains for 10-14 days. After this period of time, the processing is repeated. Ridomil Gold is able to fight any fungal infections, especially if they are at the initial stage of development. The first processing of potatoes is carried out during the growing season in preventive measures, when the weather is good. Be sure to carry out work before symptoms of the disease appear. Further spraying is carried out 9-14 days after the first treatment.

Application of fungicide for onions and garlic

To process onions and garlic, prepare a working solution of 10 grams of the drug and 100 ml of water. When it is completely dissolved, another 4 liters of water is added to the container and the solution is constantly stirred. The consumption when spraying these crops is a bucket per 100 square meters. Work is carried out in calm, dry weather, only in the evening or in the morning. The finished composition is used during the day. Plant stems should be moistened on both sides to increase the effect of the drug.

Since the pesticide Ridomil Gold is toxic, precautions should be taken during work. For example, it is important to use a respirator, goggles and protective clothing. If drops of the chemical do get on your skin, rinse it in running water. When, by chance, the drug has entered the body, you should consult a doctor. Before that, it is important to drink a few glasses of water and 4-5 tablets of activated carbon, and then induce vomiting. You can eat garlic and onions only 2-3 weeks after spraying.

Spraying flower crops

For indoor and outdoor flowers, Ridomil Gold is used in a standard proportion of 25 grams per 10 liters of water. To do this, select a small spray container. Usually work is done for young garden and indoor plants that were purchased in the greenhouse. These actions are aimed at preventing the development of possible fungal lesions and infections that may be present on the leaves.

The use of a drug called Fundazol is more important for orchids, which can be sprayed during flowering or after the peduncle has dried. The development of fungi in the tubers of this flower is the most common disease, as it begins as a result of improper watering, or due to the use of an unsuitable substrate. Ridomil Gold is also considered the most effective against rust on the leaves, which are found on rose bushes. Spraying of flowers begins during the period of active growth, when there are still no buds.

Compatibility with other drugs

Ridomil Gold is perfectly combined with other drugs, but its composition cannot be mixed with these chemicals.

If there is an idea to mix it with another composition from this group, then this mixture should be checked for compatibility. For these purposes, a separate place is selected and a cultivated plant is sprayed. If the response to the treatment was positive, then the cocktail of the two formulations can be applied to other plants. But if the reaction to spraying was negative, then these drugs are used separately. The interval between them must be at least 7 days.

In terms of its qualities, Ridomil Gold can be compared with Topaz and Skor, which protect the plant from rust, powdery mildew and late blight. If you compare it with other chemicals, then it is distinguished by reliable protection of crops up to 18 days, which is slightly higher than Ridomil Gold has. Both of these drugs can be alternated with Hom, which is easy to combine with other types of pesticides, as well as insecticides and various fertilizers. Also, Hom goes well with drugs from the dithiocarbamate group, thanks to which it is possible to prevent burns on the leaves. This composition has a long duration and is used together with Ridomil Gold, Epin, Fufanon, Tilt 250. It is forbidden to combine it with alkalis. Therefore, it is not necessary to spray with copper oxychloride and other similar chemicals before processing with Hom. The switch eliminates black and brown spots on cabbage.

Analogs of Ridomil Gold

Among the huge number of fungicides, Ridomil Gold can be replaced by many, but the most effective of them are Profit Hunger, Quadris, Metaxil and Previkur Energy.

Profit Gold. Its active ingredient is cymoxanil, which penetrates the plant and provides it with reliable protection. The second active substance of the drug is famoxadone, which gives external protection to vegetable and fruit crops.

How to distinguish a fake?

Ridomil Gold is produced by the Swiss company "Signetta" in 25 and 50 grams packaging. Its average cost for 50 grams is about 200 rubles, but if it is 3-4 times less, then this should immediately alert buyers. Counterfeit products are so high quality today that the common man can easily make mistakes. For example, the packaging of the fake and the original has an identical drawing, release date and instructions, but there are still differences between the mini. The counterfeit comes in larger packs, and it is also produced in the form of a powder, although the foreign composition is in granules. Photos of the fake can be seen on the Internet.

When buying Ridomil Gold Syngenta, a person should pay attention to:

• there is no minimum price for a high-quality, imported product;
• the composition must be granular;
• each pack has a date of manufacture and expiration date.

Unrivaled protection of potato tubers in the field and storage

RIDOMIL GOLD MC, VDG RIDOMIL GOLD MC, VDG

RIDOMIL GOLD MC, VDG BRAVO, KS and SHIRLAN, SK with an interval of 7-10 days.

All potato growers know that since the main cause of potato losses during storage is the defeat of tubers by late blight, only healthy tubers should be stored for storage. RIDOMIL GOLD MC, VDG is the only fungicide that protects not only the tops, but also the tubers. To obtain such a result, it is recommended to carry out the first two or three treatments with RIDOMIL GOLD MC, EDH at intervals of 10-14 days. Only then can you proceed to contact fungicide treatments.

Treat the field with a fungicide without waiting for the first symptoms of the disease. Treatments started after the formation of foci of infection are less effective. If the accepted methods for predicting late blight are not available to you, then carry out the first treatment when closing the tops in rows. In cases where the primary source of infection is the affected tomato seedlings, the processing of neighboring potato plantings should be started immediately, without waiting for the tops to close in rows. Apply the fungicide RIDOMIL GOLD MC, VDG 2-3 times per season, with an interval of 10-14 days only for the first treatments, but not later than the flowering phase of potato plants. Then use contact fungicides BRAVO, KS and SHIRLAN, SK with an interval of 7-10 days.

Cultivation of vegetable crops

RIDOMIL GOLD MC, VDG relieves vegetable growers of the burden of constant alarm about large crop losses. An additional benefit: product residues that are up to date.

Onions of all generations: against peronosporosis of onions RIDOMIL GOLD MC, EDG should be used for preventive spraying of plantings before symptoms appear.

Cucumbers and tomatoes: against late blight of tomatoes and peronosporosis of cucumbers RIDOMIL GOLD MC, VDG should be used for preventive spraying of plantings in order to prevent infection of plants. RIDOMIL GOLD MC, EDG also provides partial protection against diseases that appear along with late blight of tomatoes (anthracnose, alternaria, cladosporiosis, septoria) and cucumber peronospora (anthracnose, cercospora, alternariosis, cladosporiosis).

Vine

Mildew has always been and remains the most dangerous disease in vineyards, especially before, during and after flowering. RIDOMIL GOLD MC, EDC sets new standards in programs to protect vineyards from the threat of this disease.

While the contact component of the fungicide, mancozeb, protects the leaf surface, the systemic component, mefenoxam, completely penetrates the grape plant within 30 minutes, providing protection from the inside and resistance to rain washout. Mefenoxam is rapidly distributed throughout the plant, even in the new growth that appears after treatment, as well as through the thickness of the leaf, showing translaminar properties. The duration of the protective action is up to 14 days. During this period, the entire plant as a whole is reliably protected, even in case of heavy rain or high infection load.

Thanks to the properties of good adhesion and persistence, mancozeb complements the action of mefenoxam, providing protection against diseases such as rubella, phomopsis, black rot, black spot. The drug is very well tolerated by the grape culture, even promoting the growth of young shoots.

Ideal for scheduled preventive maintenance programs and forecast service programs

It is often difficult to accurately observe the dates of disease development reported by the prognosis service. Moreover, in some places, infection may occur somewhat earlier or later. In this case, you can use another advantage of the fungicide RIDOMIL GOLD MC, VDG, since it can control the development of mildew even for several days after creating conditions favorable for infection.

mancozeb

mefenoxam

Mechanism of action

Double reliability thanks to system and contact properties

The finished mixed preparation RIDOMIL GOLD MC, VDG, created using the latest PEPIT technology, includes:

40 g / kg mefenoxam, which provides internal protection:

• systemic and translaminar action - protection of treated and untreated parts of plants, new growth and tubers
• a high level of effectiveness against fungi from the class of oomycetes (pathogens of downy mildew)
• rapid decomposition in soil

This is the main part of the mixed preparation required for processing during the period of active plant growth.

640 g / kg mancozeb, which provides external protection and is

• effective contact fungicide and
• a key link in anti-resistance strategy

RIDOMIL GOLD MC, VDG is a mixed fungicide (factory mixture) containing mefenoxam and mancozeb. In the practice of cultivation of field crops and vegetables, mancozeb is recognized as an ideal partner (in terms of the mechanism of action, duration of action, reliability; additional efficiency against Alternaria solani, Rhizoctonia solani, Gloesporium and other contributes to the rapid growth of young plants). The double action is decisive: the plant is protected from the inside and from the outside. This means that the user can plan the spraying program in advance with confidence.

Systemic and translaminar properties

Systemic action: due to its systemic properties, mefenoxam spreads through the plant acropetally and basipetally, entering the untreated parts of the plant. RIDOMIL GOLD MC, VDG surpasses other modern fungicides in terms of reliability, especially in difficult conditions. The entire plant, including new growth, is protected by the drug, regardless of the infectious load. The active ingredient is almost completely distributed throughout the plant within 30 minutes after treatment. This means fewer treatments and no need for re-treatments after rain.

Translaminar action: the active ingredient penetrates from the treated side of the sheet through the inner tissues to the untreated side, thus protecting both sides of the sheet.
