Advantages and disadvantages of the fungicide Kuproksat, period of action, application

Advantages of the product

Kuproksat has a number of advantages, which is why it is very popular among summer residents. The advantages include:

• resistance to moisture and precipitation;
• lack of resistance of the main substance;
• wide spectrum of action;
• compatibility with pesticides in tank formulations;
• high efficiency;
• eliminating the risk of re-development of fungal pathology;
• ease of use;
• formation of a protective dense film on the foliage;
• environmental friendliness.

This drug is necessary to protect plant crops from diseases such as:

• brown spot;
• macrosporiosis;
• peronosporosis;
• rhizoctoniasis;
• apple scab;
• grape mildew;
• late blight;
• powdery mildew;
• angular spotting;
• cercospora blight

It also protects plants from other diseases that interfere with their growth. Kuproksat remains effective under any technical conditions, at temperatures from 0 to 35 degrees. When used correctly, it is characterized by the absence of phytotoxicity.

How does cuproxat work?

The drug kills the parasitic form upon direct contact. The active substance penetrates inside the parasitic cell due to the fact that copper ions interact with fungal enzymes, reducing their activity and blocking the respiratory function. Due to this action, the processes of nonspecific protein denaturation are activated, which is incompatible with the development of the microorganism.

Gradually, copper sulfate accumulates in spore particles and cells until they are completely destroyed.

Therefore, when the disease develops, the effectiveness of the drug decreases several times.

Thus, the most effective method of using Kuproxat is not the treatment of fungal pathology, but its prevention.

The drug is compatible with a wide range of insecticides and other fungicides that are used during the same period. But before using them together, it is necessary to conduct a test for a physical and chemical reaction. In its absence, the complex can be used for plants.

The period of protective action of Kuproxat at temperatures from 0 to 35 degrees is 7-10 days. Sometimes it can increase to 3 weeks. This period will depend only on the type of fungal pathology affecting the plant and on the crop.

Operating principle

The fungicide kills the parasite on direct contact. The excellent effect of using Kuproxat occurs as a result of the penetration of the active agent into the cells of fungal parasites, causing a slowdown in plant development.

This occurs due to the fact that copper ions interact with the enzymes of pathogenic fungi and reduce their activity and disrupt respiratory functions. As a consequence, nonspecific denaturation of the protein occurs, and this process is incompatible with the growth of the organism. Copper sulfate continues to accumulate in spores and cells until they are completely destroyed.

In the event that the disease has already developed, the effectiveness of the drug “Kuproksat” will drop several times. This is due to the fact that it is not intended to treat fungi, but to prevent, eradicate and prevent their occurrence.

Instructions for use

The instructions for use for this product warn that before using the drug, you need to prepare a working solution from it. To do this, you must use the following recommendations:

1. The container with the drug is thoroughly shaken.
2. The recommended dosage is measured, which differs for the treatment of each crop.
3. The container with the sprayer is half filled with water, and then the substance is added to it.
4. Then the rest of the water is poured in.

In order to correctly measure the dosage of the drug, you must use the following information:

• 70 milliliters per hundred square meters is recommended for sugar beets;
• 50-60ml/comb – used for spraying grapes;
• 50 ml/comb – used for processing apple trees, tomatoes, cucumbers;
• 30-50 milliliters per hundred square meters - use for spraying hops.

There is also an instruction describing the required amount of working fluid:

• for apple trees and grapes, 10 liters of solution per hundred square meters should be used;
• 1 hundred square meters of cucumbers should be treated with 8-10 liters of solution;
• tomatoes are sprayed with 4-10 liters per hundred square meters;
• one hundred square meters of sugar beets are treated with 4-6 liters of liquid.

If this proportion is observed, the use of the drug is safe, and its main substance exhibits maximum effectiveness.

Spraying method

In order for the treated crops to be protected from fungal pathologies, the following nuances must be taken into account during their processing:

1. The treatment procedure is only required on a sunny day.
2. Do not use the drug 2-3 hours before or during rain.
3. Plant crops are evenly covered with a working solution prepared in advance.
4. Excessive spot application to certain planting areas is prohibited.
5. During spraying, the wind speed should not exceed 4 m/s.
6. During distribution of the drug, it is necessary to avoid its contact with other sensitive crop plants, which can be destroyed under the influence of the drug.

The recommendations also concern the time of spraying the working solution:

1. Primary processing must be done during the growing season.
2. The second treatment is carried out during flowering. Its main function is to prevent the occurrence of pathology. Spraying is carried out during loosening of inflorescences and bud formation. Experienced summer residents have determined that this process begins on average 7-12 days before flowering.
3. The last treatment is carried out 3-4 weeks before harvest. It is absolutely impossible to shorten this period, since in this case toxic substances will accumulate in the fruits and end up on people’s tables.

Each type of planting requires a different frequency of spraying, for example, grapes should be treated four times, cucumbers - three times, and apples, sugar beets, tomatoes - twice.

Grape processing

It is worth considering that the instructions for using Kuproxat for processing grapes differ from the recommendations for spraying other crops.

It consists of carrying out primary processing.

The first spraying of grapes is carried out at the moment when the vine has grown to 20-30 centimeters, and the size of the leaf plate is up to 3 centimeters in diameter.

Subsequent processing is carried out according to the general scheme.

Advantages and disadvantages of the product

Kuproxat occupies a leading place among copper-containing fungicidal substances. It is considered a standard, since there are no analogues with a similar action and effect.

In practice, it has been proven that the drug is indispensable when growing potatoes and sugar beets. But the most important fact, which speaks for itself, is that Kuproxat has no resistance.

The positive qualities of the fungicide also include:

• non-phytotoxic if diluted and used according to instructions;
• protection for up to one and a half weeks, regardless of weather conditions;
• is active in the temperature range 0 - +35 degrees;
• is not washed off by rain or during watering;
• easy preparation of the working solution, no precipitation;
• immediate action after application;
• an environmentally friendly product, it can be combined with other drugs and tank mixtures;
• After use, relapse of infection is impossible for a long time.

The negative side of using the substance is the inability to carry out treatment at all stages of the growing season. Therefore, it is recommended to carry out the first actions in the absence of sub-zero temperatures.

A special point when using a fungicide is strict adherence to doses during processing, as well as when preparing the working mixture. Otherwise, intoxication is possible.

Precautionary measures

To prevent the toxicity of the drug from harming the health of the summer resident, during its use you should follow the safety rules:

• the person spraying the working solution must wear a respirator, otherwise toxins entering through the respiratory tract will be instantly absorbed into the blood, bypassing the liver;
• Clothing should cover all areas of the body to avoid contact with the skin;
• the person must use a hat;
• When spraying, you should use safety glasses to prevent the risk of getting the product into your eyes.

Kuproxate is included in the third toxicity group, which indicates its safety in relation to humans when sprayed correctly. It also does not harm the environment, flora and fauna. But this product should not be used near bodies of water inhabited by fish.

You should also pay special attention to the presence of bees nearby: insects must be at least 4 kilometers away from the sprayed composition within 24 hours. Otherwise, insects may die in direct contact with the product.

Fungicide "Kuproksat": instructions for use

Kuproxat is used as a preventive and eradicative agent against viral diseases caused by fungi; the drug effectively protects garden and vegetable crops. Thanks to its broad effects, resistance to rinsing and lack of resistance, Kuproxat has remained one of the most popular for many years. Read the detailed instructions for use of the drug.

Description of the drug

Cuproxate (fungicide and pesticide) belongs to the chemical class of inorganic substances, the main active element is tribasic copper sulfate pentahydrate. The dry product is a white crystalline substance. After treatment, the aqueous solution forms a visible, dense film on the leaves and bark of plants, which protects tissues from the penetration and germination of fungal spores and suppresses parasitic organisms in the early stages of development.

Contact fungicide is used for the treatment and prevention of diseases of industrial, flower, vegetable crops and…

Features of Kuproxat

Kuproksat is allowed to be used for the manufacture of tank mixtures. But before using solutions, it is necessary to analyze the physico-chemical reaction; processing is permissible only in its absence. Kuproxat is the standard among copper-containing fungicides; as for analogues, the main one is Bordeaux mixture. The following products can be used as substitutes:

• "Blue Bordeaux";
• "Kuprozan";
• "Polycarbacin";
• "Skor";
• "Bayleton";
• "Mikal";
• "Acrobat MC";
• "Ridomil MC".

The fungicide is effective during periods with frequent precipitation; a positive result is noticeable within 24 hours in the fields and after 3 days in households. Kuproxat is not addictive to pathogens; there is no need to select similar agents for replacement or rotation. The drug is easy to use, it completely dissolves in water, does not form even the slightest sediment (no need to shake periodically) and does not clog the sprayer. Kuproxat is not suitable for the treatment of infected crops; it is used exclusively for preventive purposes.

Manufacturers and storage conditions

The production of the drug is carried out by 2 large companies - Vassma and Nupharm, both organizations have already been tested and do not cause any complaints from gardeners. The fungicide is produced in small bags and flasks of small volume, for treating small areas, or in plastic canisters of 10, 25 and 50 liters in the form of a concentrated (34.5%) aqueous emulsion of blue color, thick consistency.

The product (in its original packaging) should be stored in a dark place, away from children and pets, at a temperature of 0 to +25 degrees, away from food and medicine. The date of manufacture is on the labels or on the canister; the maximum shelf life is 2 years. Do not leave the drug for a long time in a room where the temperature drops below -1 degree; the main substance quickly loses its properties in such conditions.

Mechanism of action

Cuproxat destroys spores by direct contact. The active components of the drug penetrate and accumulate inside fungal cells. Copper microparticles, interacting with the enzymes of harmful organisms, reduce their tone and block respiratory function. This effect leads to a gradual but fairly rapid destruction of fungi. Kuproxat prevents the resumption of the pathogen, but it is better to carry out treatments annually.

Active substance, release form, container

The Austrian manufacturer Nufarm took a responsible approach to creating a fungicide. Kuproxat is defined as highly effective, since by all indicators the drug really provides powerful protection to crops in the early stages of the disease or before the first signs appear.

The action of the substance is aimed at suppressing pathogenic microorganisms and spores. High efficiency is achieved thanks to the composition of Kuproxat - copper sulfate.

The release form of the fungicide is a suspension, but of increased concentration. Therefore, before starting use, it will be necessary to dilute it in the required dose.

Kuproxat acts quickly and is a systemic drug. At the same time, the fungicide is contact and fast-acting.

After applying the working mixture, Kuproxat turns into an invisible film, which serves as a protective barrier against fungal infections and viruses. If the pathogen was on the plant before spraying, then the film becomes a blocker of the spread and respiration of pathogens.

The packaging of the drug can be either 50 ml or 250 ml. Also for large areas, containers of 10 and 25 liters are offered.

Instructions for use

There is no single recipe for a solution that is suitable for all crops; a separate mixture of different concentrations is prepared for each plant. To work with the drug, you should prepare a fine sprayer, since targeted (spot) spraying is not recommended. Wash all containers used thoroughly. How to properly prepare the working solution:

• shake the container with Kuproxat;
• measure the recommended amount of fungicide;
• Fill half the volume of the sprayer with slightly warm water;
• add the drug, close the sprayer opening, shake the mixture for 30 seconds;
• add water to the required amount.

The solution can be prepared in any convenient container, for example, in a bucket, then carefully pour into a sprayer. Use only plastic, enamel or glass containers; in extreme cases, you can use stainless metal containers. Basic information about the correct use of Kuproxat, as well as recipes for mixtures, are listed in the table.

Gardeners have long adopted the low-toxic fungicide Brunka. It is used to process grapes, fruit trees and…

In addition to protecting plants from fungal diseases, the product is used as foliar feeding. The main substance of Cuproxate, copper, is one of the most important microelements necessary for proper nutrition of plants. If there is a lack of copper, the transition to the reproductive phase is disrupted; proper use of the drug helps to increase productivity.

How to prepare a working mixture

For potatoes and tomatoes, take 40-50 ml of concentrated solution per 5 liters of water, and for apple trees - up to 80 ml. It is enough to measure the substance in a glass and add it to a sprinkler tank half filled with water. After this, the drug is carefully mixed and the tank is topped up to the final mark. The fungicide container is thoroughly washed with water and disposed of. After using equipment in the fields, the tank must be rinsed. Used water should not be poured onto the ground or other food crops.

Precautions and toxicity

Cuproxate is classified as hazard class 3 (toxicity) for animals, humans and bees. If there is an apiary located near the treated area, you can open the boxes and release the insects a day after spraying. The drug is dangerous for fish and other aquatic organisms; Kuproxat is prohibited from being used in the sanitary zone around fishery complexes and other bodies of water (no closer than 2 km from the shores).

Be careful not to get the product on your skin or eyes, be sure to protect your respiratory system, and do not smoke or eat while working. In case of contact of the product with skin, immediately wash the contaminated area with plenty of running water and soap. If symptoms of poisoning appear (nausea, darkening of the eyes, loss of strength, difficulty breathing), you should immediately drink 500 ml of water and 3 tablets of activated carbon, and then consult a doctor. Any work with Kuproxat is carried out in goggles, rubber gloves, a respirator, protective clothing and a hat. After completing all procedures, the clothes are washed.

The drug is not phytotoxic, but only if you use it strictly according to the instructions. Be sure to study the characteristics of apple varieties; some varieties have increased sensitivity to copper (Golden Delicious, Golden Spur, King David, Idared, Corey, Jonared, Mekintosh, etc.). After spraying, a kind of “network” may appear on the leaves and fruits, which will lead to the formation of rust, cracking and shedding of apples.

The drug Kuproxat is not an expensive product; it is time-tested and is preferred not only by owners of summer cottages or small vegetable gardens, but also by large industrial agricultural firms. Using the product strictly according to the instructions, you will receive a bountiful harvest of healthy, environmentally friendly vegetables, berries and fruits, without harming the environment and your health.

Features of the fungicide

Kuproxat is a contact fungicide with protective properties. The active ingredient is tribasic copper sulfate. Its content in the preparation is 345 g/l. The main analogue of the fungicide is Bordeaux mixture.

A solution of copper sulfate forms a protective film on the surface of plants. As a result, an obstacle is created for the germination of fungal spores.

The active ingredient of the fungicide Kuproxat blocks the respiratory function of microorganisms. Copper sulfate accumulates in fungal cells and completely destroys them. Therefore, the drug Kuproxat is effective as a prophylactic agent before the onset of infection.

The drug is used to protect against fungal diseases of various crops: fruit trees, vegetables, grapes. If dosages are observed, copper sulfate is not phytotoxic to plants.

Kuproxat is effective at temperatures from 0 to +35 °C. The protective effect lasts for 7-10 days.

Among all drugs containing copper, Kuproxat is considered the standard. The fungicide is effective even in rainy weather. The protective film is not washed off after exposure to moisture.

The manufacturer of Kuproxat is the Austrian company Nupharm. The fungicide has the form of a liquid suspension and is supplied in plastic containers with a capacity of 50 ml to 25 liters.

Advantages and disadvantages

Like any other fungicide, Kuproksat has its advantages and disadvantages.

Advantages and disadvantages

Provides complete protection against infection within 2 weeks from the date of first treatment. Non-toxic in small doses for plants, people and animals. It quickly settles on plants and is not washed off. Valid at any temperature and humidity.

The need to constantly update the protective layer of the drug. If the application technology is not followed, it can become dangerous for the ecosystem. Cannot be used immediately before harvest. Overdose can cause serious poisoning and death.

Application procedure

Fungicide Kuproxat is used to prepare a working solution. Its concentration depends on the type of crop being treated. The solution requires enamel, glass or plastic containers.

First, a measured amount of the drug Kuproxat is dissolved in a small volume of water. Gradually add the remaining water to the solution.

The solution is used within 24 hours after preparation. Plants are treated by spraying on the leaf. This requires a spray bottle with a fine mist.

With high humidity, the apple tree may suffer from scab. This is a fungal disease that affects young shoots, leaves and ovaries. Swamp-colored spots appear on them, which gradually darken and lead to the formation of cracks.

To protect apple trees from scab, prepare a solution based on the fungicide Kuproxat. According to the instructions for use, to treat 1 hundred square meters of plantings, 50 ml of suspension is required, which is mixed with 10 liters of water.

Spraying is carried out during the growing season of the apple tree, but no more than 3 times during the season. The first treatment with the fungicide Kuproxat is performed when the buds open. 3 weeks before harvesting apples, all treatments are stopped.

There are varieties of apple trees that are sensitive to copper-based fungicides. After their processing during the flowering period, a so-called “net” is formed on the leaves and fruits.

Stone fruits

Peach, apricot and other stone fruits are susceptible to the diseases moniliosis, leaf curl, and clusterosporiasis. Diseases spread quickly and lead to crop loss.

Preventive treatments for stone fruit crops begin in the spring when the buds open. During the season, it is allowed to perform 4 sprayings with a solution of the drug Kuproxat. Wait between procedures for 7 to 10 days. The last spraying is carried out 25 days before harvesting.

To 10 liters of water, according to the instructions for use, add 45 ml of suspension to the fungicide Kuproxat. The resulting solution is enough to treat 1 hectare of orchard.

Mildew is a dangerous disease of grapes. The disease is fungal in nature and is diagnosed by the presence of a white coating on the shoots and leaves. As a result, grape leaves die, the plant’s immunity decreases and its yield drops.

Preventive treatments help avoid the development of the disease. During the growing season, plantings are sprayed with a solution of the drug Kuproxat. According to the instructions for use, 6 ml of concentrate is required for 1 liter of water. The prepared solution is consumed per 10 sq. m of vineyard.

In the second half of summer, signs of late blight may appear on potatoes. The causative agent of the disease is a fungus that attacks potato shoots and tubers. Late blight is determined by the presence of brown spots covered with a grayish coating. The affected parts of the bush die off, and in advanced cases the plantings die.

Another dangerous potato disease is Alternaria blight, which looks like dry gray-brown spots. The defeat spreads to the leaves, which turn yellow and die, and gradually spreads to the tubers.

Protective measures are carried out after planting potatoes. During the season, you can treat the plantings with Kuproxat three times, but not more than once every 10 days.

The spray solution is prepared according to the instructions for use of the drug Kuproxat. For 10 water, 50 ml of suspension is required. The prepared solution is enough to treat 1 hundred square meters of plantings.

Reviews from gardeners

Larisa, 35 years old, Saratov Kuproksat is an excellent product that helped protect roses from black spot. As soon as I noticed that the leaves were starting to turn yellow and fall off, I started preparing the solution. The drug contains an adhesive and stays on the leaves for a long time. The decorative properties of the bush suffer from this, but the roses develop beautifully throughout the season. Valery, 48 years old, Pyatigorsk I have been growing grapes for more than 10 years. I have known the drug Kuproxat for quite a long time. Its main advantage is a good antibacterial effect. The product acts against harmful fungus. However, after spraying, only those shoots on which there is a solution remain protected. Elizaveta, 27 years old, Chelyabinsk I use the fungicide Kuproksat instead of Bordeaux mixture. The product protects the apple tree from the spread of scab. Last year the disease destroyed most of the crop. I use the drug at the beginning of the growing season, when the trees are just waking up after winter. A very effective remedy, this year there were no diseases and we managed to harvest a good harvest of apples in the garden.

Precautionary measures

The fungicide Kuproksat is assigned hazard class 3 to humans and bees. If there is an apiary nearby, then bees are allowed to be released 12-24 hours after spraying the plantings.

The active ingredient of the fungicide Kuproxat poses a danger to fish and other aquatic organisms. Treatment is carried out away from reservoirs, rivers and other similar objects.

To spray plants, choose the morning or evening time, when there is no direct sunlight, rain or strong wind.

It is important to avoid contact of the solution with the skin and mucous membranes. If the substance gets into exposed areas, rinse them with frequent water.

In case of poisoning with the drug Kuproksat, the victim is given 2 glasses of clean water and 3 tablets of sorbent (activated carbon) to drink. Be sure to seek medical help.

Fungicide Kuproxat is stored in a dry place at temperatures above 0 °C. The product is kept away from children, animals, food and medicines.
