Fungicide Coside 2000

Every gardener or gardener who seriously deals with his personal plot wants to reap a rich harvest and protect his plants from various infections. When the usual measures to combat them do not cope, agrochemicals come to the aid of summer residents. Coside 2000 is a modern broad-spectrum fungicide. We will give detailed instructions for the use of the drug, get acquainted with its features and reviews of agricultural workers.

Features of the drug

Fungicide Coside 2000 is one of the newest, contact preparations based on copper, which is designed to protect vegetable and horticultural crops from infectious lesions. It effectively prevents both fungal diseases and bacterial ones. The protective effect lasts up to two weeks.

Purpose and form of release

Potatoes, tomatoes, onions, peaches, grapes, apple trees, strawberries and many other crops are treated with fungicide. Coside is used to prevent a wide range of diseases:

  • alternaria (dry spot);
  • late blight (brown rot);
  • peronosporosis (downy mildew);
  • scab;
  • moniliosis (fruit rot);
  • mildew;
  • gray rot;
  • bacterial spotting.

The drug is available in the form of blue-green water-soluble granules. In the markets and in online stores, they offer various packaging of the pesticide Cosside. For private gardening, you can purchase sachets of 10, 20, 25 and 100 g of the substance. Large agricultural producers prefer to buy the fungicide in large quantities - 1, 5 and 10 kg each.

Mechanism of action

The active ingredient of the preparation Cosside 2000 is copper hydroxide, the concentration of which in dry matter is 54% (for 1 kg of granules - 540 g of copper). With prophylactic spraying, a protective film forms on the surface of the plant, which protects the culture from pathogenic microorganisms. This layer is created by small copper crystals that envelop the leaves.

As soon as the fungicide solution enters the plant, bivalent copper ions disrupt the vital processes of bacteria and fungi: protein synthesis, the work of cell membranes and various enzymes.


According to summer residents, the main advantages of the Koside agrochemical are:

  • simultaneous control of fungal and bacterial infections;
  • high content of bioactive copper;
  • has unique chemical and physical properties of the formulation;
  • the likelihood of addiction of pathogenic organisms to the drug is small, since it has a multifaceted effect;
  • the fungicide is not sensitive to changes in weather conditions, therefore it is resistant to rain and watering;
  • economical consumption;
  • has low toxicity for both insects and humans;
  • the product dissolves quickly in water, does not dust during processing;
  • has good compatibility with many drugs.

A distinctive characteristic of the drug is that it is suitable for many crops and has a wide spectrum of action.


Despite a number of positive aspects, do not forget that the Coside fungicide belongs to pesticides. Therefore, it is important to follow standard safety precautions when handling it.

The disadvantages of the drug include:

  • Suitable only for preventive measures. It is not used for therapeutic purposes.
  • Protects plants only from the outside, as it does not penetrate into plant tissue.
  • Inconvenient packaging and storage.
  • If the air temperature is above +26 degrees, then spraying should not be done, as burns may appear on the leaves.

By following all the recommendations for the use of the fungicide Coside 2000, the disadvantages can be avoided.

Preparation of working solution

To spray plants with the fungicide Coside, you need to choose the evening or morning time so that the sun cannot burn the leaves. It is desirable that the weather is dry but cloudy. The working solution is prepared using a special technique. Measure the required amount of granules and dissolve them in a small amount of pure water. The resulting concentrate is poured into a spray tank filled with water. Mix the liquid well with a wooden stick until smooth.

Processing of horticultural and vegetable crops is carried out during their growing season. The first spray is carried out to prevent infections in early spring. Subsequent - with the manifestation of visible symptoms of the disease. The maximum number of sprays is 2-4, depending on the type of crop. The gap between them should not be less than a week. Do not spray flowering plants with fungicide.

Attention! It is allowed to go out to the site to perform various works three days after spraying crops.


Fungicide Coside 2000 prevents Alternaria, Septoria, Macrosporiosis and Late Blight in tomatoes. These insidious diseases reduce the quality and volume of the crop several times, and in advanced cases can lead to the death of the plant.

To protect the beds, a solution of the fungicide Koside 2000 is prepared at the rate of 50 g of the substance per 10 liters of water. According to the instructions for use, tomatoes can be sprayed no more than 4 times with an interval of 1-2 weeks. On average, 300 liters of working fluid (2.5 kg of the drug) are consumed per hectare. You can collect and eat vegetables no earlier than two weeks after the last spraying.


Any gardener, both experienced and beginner, can face such a problem as late blight and alternaria on potatoes. The planting of the crop effectively protects preparations containing copper, for example, the fungicide Coside.

To prepare the working fluid, 50 g of granules are poured into a ten-liter bucket of water. The potatoes are sprayed 4 times with a spray bottle. The interval between preventive procedures is 8-12 days. On 1 hectare of the plot, 300 liters of solution (1500-2000 g of an agrochemical) are used. The last treatment should be carried out 15 days before harvesting the tubers.


In cold and rainy weather, onions can attack downy mildew. This is an insidious disease, which is especially dangerous for the testes, since the seeds obtained will not yield a crop.

The disease is best prevented with the fungicide Cossid. To do this, measure 50 g of the substance, add it to a 10 liter bucket of water and stir thoroughly. The resulting solution is sprayed on the affected plants four times with an interval of 2 weeks. Prophylaxis should be carried out 2 weeks before harvest.

Important! If the fungicide Coside was used to treat peronosporosis, then only its bulb can be eaten.


The most common and dangerous disease in the vineyard is mildew. Leaves and berries are affected, which become unsuitable for food and winemaking. Timely prophylaxis with the use of the fungicide Coside 2000 will save the vine from downy mildew.

The working fluid is mixed from 30 g of the preparation and 10 liters of pure water. The maximum number of sprays of the vineyard is 4. Each subsequent treatment should be carried out no earlier than after 10-12 days. Berries are allowed to pick one month after the last spray.


When flower buds begin to bloom in the spring, the fruit tree can start to grow curly. The spores of this insidious disease are found under the scales of the kidneys. Therefore, it is important to spray the peach early with Cosside 2000.

The fruit tree is treated with a fungicide 2 times: before the appearance of flowers and in the green cone phase. The first atomization is carried out with a more concentrated solution at the rate of 60 g of the drug per 10 liters of water. For the second spraying, a liquid is prepared from 25 g of granules and ten liters of water. 900-1000 liters of working solution (2-6 kg of fungicide) are consumed per hectare. The fruits are harvested 30 days after the last prophylactic procedure.

Apple tree

The prophylactic use of the preparation Coside 2000 guarantees effective protection of the apple tree from scab and brown spot.

The fruit tree is sprayed no more than 4 times. The first time it is treated during the swelling of the buds, the second - when the buds begin to separate, the following with an interval of 10-14 days. For apple trees, the fungicide Koside 2000 is used in the following dosage: for 10 liters of water, 25-30 g of the drug. 800-900 liters of solution (2-2.5 kg of granules) are consumed per hectare of land.

Important! Do not spray the apple tree during flowering.


Products that contain copper are highly effective in combating strawberry brown spot. One of these is the fungicide Cossid.

For spraying plantings in 10 liters of water, dissolve 20 g of the drug. The maximum number of strawberry treatments per season is no more than 3. The first procedure is carried out in the spring before flowering of the berry crop. The fungicide spraying is repeated after 15 days. In the fall, you can carry out an additional procedure immediately after harvesting.

Analogs and compatibility with other drugs

Fungicide Coside 2000 can be used in tank mixtures with other preparations. Incompatible with organophosphate insecticides and preparations containing aluminum fosethyl and thiram. Also, it is not recommended to mix it with acidic substances.

The following drugs are the analogues of Coside: Cupid, Meteor and Mercury. They are all made on the basis of copper sulfate.

Safety regulations

Fungicide Coside is not dangerous to humans (toxicity class 3) and moderately toxic to bees and aquatic organisms. It is forbidden to carry out work near apiaries and reservoirs.

Despite the fact that the drug is not toxic, it can cause irritation of the skin and mucous membranes. Therefore, during preventive procedures, you should adhere to standard safety measures:

Reviews of summer residents

Vladimir, 42 years old, Ivanovo

Two years ago, I purchased the fungicide Cossid and began using it to prevent mildew in the vineyard. While the neighbor's plant was affected by this disease, I did not observe traces of the parasitic fungus on my grapes. I read the instructions and was pleasantly surprised that it can be used for many cultures. He began to process the apple tree and tomatoes. Copper does an excellent job of protecting trees and garden plantings.


Fungicide Coside is a prophylactic copper-containing agent that is characterized by low toxicity. Not many summer residents know about its existence, which is frustrating, because it is an effective drug that combines many advantages.
