Fungicide 'Kuproksat': description, instructions for use

Fungicides are chemicals used to combat fungal plant diseases. In addition, they are used to pickle the seeds before planting, destroying the spores of parasites on their surface. These are excellent helpers for the gardener, although their concentrates are toxic to humans and animals. Fungicides are widely marketed, as are common pesticides. Let's consider the instructions for use of the drug "Kuproksat" - a common fungicide.

Active ingredient, release form, container

"Kuproksat" - inorganic substance. It is commonly referred to as contact fungicides that contain copper. Its active ingredient is copper (II) sulfate, pentahydrate, which is the main component. It is an anhydrous white crystalline medium. The form of the drug - 34.5% suspension concentrate. The fungicide is produced in a factory plastic canister with a volume of 10 or 25 liters, sometimes it is possible to find smaller packaging.

Cultivated crops

The main cultures on which it is recommended to apply Kuproksat are:

different types of apple trees;
different types of pear trees;
cucumbers;
tomatoes;
zucchini;
vine;
potato;
hop;
sugar beet.

Spectrum of action

The fungicide protects plants from many fungi, such as scab apples, mildew grapes, brown spotting, angular spotting, late blight of potatoes and tomatoes, peronosporaz cucumbers, powdery mildew, macrosporosis, rhizoctoniosis, sugar beet gestos and other diseases that prevent the growth of crops.

Did you know? The fungus is not always bad, sometimes it benefits. For example, entomopathogenic fungi have earned a good reputation of biopesticides for the destruction of plant pests. They are able to infect and kill many insects. Unfortunately, there is a reverse side of the coin. In the VIII-XIX centuries, the fungus "got" to the silkworm and destroyed the European sericulture, which at that time brought Europe an excellent income.

Drug benefits

Due to the active substance and the principle of operation, the drug has many advantages:

Broad spectrum of action.
Resistant to rain.
The market leader in fungicides due to its effectiveness.
Does not allow the resumption of pathogenic fungus.
It is well compatible with other pesticides in tank mixes.
Reliable protection due to the formation of a dense film on the leaves.
Lack of resistance of the active substance.
Instant effect.
Environmentally friendly use.
Convenient to use, does not precipitate, does not clog the sprayer.
Fungicide "Kuproksat" is able to operate under any technical conditions, even at temperatures ranging from 0 ° C to 35 ° C.
Prolonged protective action.
Complete lack of phytotoxicity with proper use.

Operating principle

Fungicide kills the parasite by direct contact. The excellent effect of using Kuproksat results from the penetration of the active agent into the cells of fungal parasites, which provoke a slowdown in the development of the plant.

This is due to the fact that copper ions enter into action with enzymes of pathogenic fungi and reduce their activity, impair respiratory functions. As a result, non-specific protein denaturation occurs,and this process is incompatible with the growth of the organism. Copper sulphate continues to accumulate in spores and cells until they are completely destroyed.

In the event that diseases have already developed, the effectiveness of the drug "Kuproksat" will fall several times. This is due to the fact that it is not intended for the treatment of fungi, but for the prevention, eradication and prevention of their appearance.

Common fungicides are Abiga-Pik, Alirin B, Albit, Gamair, Gliocladin, Quadris, bluestone, Ordan, Oxyh, Scor, Strobe, Thanos, Topaz, Trichodermin, Fundazol, Fitolavin, Fitosporin-M, Horus, Hom, Ridomil holol, Gomal, Ridomil holol, Fitolorin, Fitosporin-M, Horus, Hom, Ridomil holol, Hom, Ridomil holol.

Application regulations

Before applying Kuproksat, it is necessary to prepare a working solution. The instruction is:

Shake the container well and open it.
Measure the amount of fungicide needed for a particular culture.
Fill the sprayer with water, filling approximately half of the tank.
Pour the pesticide into the tank of the culture apparatus.
Add the rest of the water to the spray tank.

Important! Before using the sprayer to treat the crop, be sure to rinse it well with clean water so that there are no residues of previous pesticides.

It is necessary to spray cultures with a fungicide on a clear day.Pesticide use is not recommended for 2-3 hours before rain or during rain. Plants it is important to evenly cover the working solution with a special apparatus. Do not allow abundant point application of the solution to certain parts of the culture.

The consumption rates of the Kuproksat preparation are as follows: apples, tomatoes and cucumbers - 50 ml / hundred, grapes - 50-60 ml / hundred, sugar beets - 70 ml / hundred, hops - 30-50 ml / hundred. The amount of working fluid consumption for efficient and safe spraying of crops is as follows: apples - 10 l / sot, cucumbers - 8-10 l / sot, tomatoes - 4-10 l / sot, grapes - 10 l / sot, sugar beet - 4-6 l / sot.

All plants must be processed during the growing season. The rate of spraying is as follows: apples, sugar beets and tomatoes - 3, cucumbers - 2, grape vine - 4 times.

Instructions for use "Kuproksat" on grapes is somewhat different from the regulations for the treatment of other crops. This applies to the first spraying of the plant, which is best done when the vine has grown to 20-30 centimeters, and the size of the leaves is up to 3 centimeters in diameter.

The following treatment with a fungicide plays a reserve role and is performed as a disease prevention during the flowering period of the crop.It must necessarily be made at the stage of loosening the inflorescences and strings of buds. It usually falls on a period of 7-12 days immediately before the start of flowering. With proper use, Kuproksat begins to act immediately after application.

The manufacturer warns that in order to be safe, it is necessary to use at least a respirator when working with a pesticide, because through the respiratory tract there is an instant absorption of toxins into the blood, bypassing the hepatic barrier. Clothing of a person who is engaged in processing culture should protect his body as much as possible. This also applies to headgear. Otherwise, the body may be poisoned with toxic chemicals.

The last processing of crops is necessary to produce no later than 3-4 weeks before harvest. Otherwise, toxic substances may remain in the plant organisms that will get "on the table" to a person.

Important! It is recommended to spray the drug "Kuproksat" at wind speeds up to 4-6 m / s. Avoid contact of the fungicide with neighboring sensitive cultures, as they can be destroyed.

This drug works well in compatibility with a wide range of insecticides and other fungicides, which are used in the same period.Although the manufacturer warns that before preparing the tank mix, to make sure that you do not harm the culture, it is necessary to make a test for physical and chemical compatibility, stability, and the absence of a toxic reaction of the ingredients.

Do not store ready tank mixtures for a long time, they should be used immediately after the cooking process.

Period of protective action

For the Kuproksat fungicide, the standard period of protective action at normal temperature (0-35 ° C) is 7 to 10 days. In some cases, it can last up to three weeks. Much depends on the type of fungus and the culture itself.

Toxicity

The drug is not phytotoxic if it is used strictly according to the instructions. It is worth paying special attention to the processing of varieties of apple trees that are sensitive to copper: in the period after flowering as a result of spraying, a so-called “grid” may appear on their leaves and fruits.

"Kuproksat" refers to the third class of toxicity. This means that, subject to the use of the regulations, it does not cause irreparable harm to humans and other mammals, birds, useful fauna and flora.It is not recommended to use pesticide near the water bodies inhabited by fish. This may adversely affect them.

Before spraying, particular attention should be paid to finding a number of bees. "Kuproksat" refers to the fourth class of toxicity for them. Nevertheless, it is recommended that insects be at a distance of at least 3-4 kilometers from the framed culture during the day. This restriction will save bees from death.

Did you know? In 1885, the world's first fungicide was invented. Its author was the French scientist Alexander Milard. The drug was a Bordeaux liquid to protect the vine from mildew.

Storage conditions

Fungicide "Kuproksat", according to the instructions, must be stored in a dark, cool, out of reach of children at a temperature of from 0 ° C to 25 ° C. The shelf life of the drug is indicated on the original packaging. It is 2 years from the date of its manufacture, subject to proper storage.
