Fungal diseases pose a danger to fruit trees, grapes and potatoes. Contact preparations help contain the spread of the fungus. One of them is Kuproxat, which contains copper compounds. After treatment, plants are protected from the penetration of fungal spores.
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
The main advantages of the drug Kuproxat:
- high quality of active ingredient;
- protects against dangerous diseases affecting garden crops;
- forms reliable protection resistant to adverse weather conditions;
- does not cause addiction in pathogenic microorganisms;
- compatible with other drugs.
Flaws
Before using the fungicide Kuproxat, take into account its disadvantages:
- compliance with safety regulations is required;
- restrictions on use depending on the stage of vegetation;
- has only a preventive effect.
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.
Apple tree
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.
Grape
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.
Potato
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.
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.
