Fungal diseases pose a threat to fruit trees, grapes and potatoes. Contact preparations help to contain the spread of the fungus. One of them is Cuproxat, which contains copper compounds. After treatment, the plants are protected from the penetration of fungal spores.
Features of the fungicide
Cuproxat 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 liquid.
Copper sulfate solution forms a protective film on the plant surface. As a result, an obstacle is created for the germination of fungal spores.
The active ingredient of the fungicide Kuproksat blocks the respiratory function of microorganisms. Copper sulfate accumulates in fungal cells and completely destroys them. Therefore, the drug Cuproxat is effective as a prophylactic agent before infection.
The drug is used to protect against fungal diseases of various crops: fruit trees, vegetables, grapes. If the dosages are observed, copper sulfate is not phytotoxic to plants.
Cuproxat acts at temperatures from 0 to +35 ° C. The protective effect lasts for 7-10 days.
Among all preparations containing copper, Cuproxat 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 Cuproxat is the Austrian company Nufarm. The fungicide is in the form of a liquid suspension and is supplied in a plastic container with a capacity of 50 ml to 25 liters.
Benefits
The main advantages of the drug Cuproxat:
- high quality of the active substance;
- protects against dangerous diseases affecting horticultural crops;
- forms reliable protection resistant to adverse weather conditions;
- does not cause addiction in pathogenic microorganisms;
- compatible with other drugs.
disadvantages
Before using the fungicide Cuproxat, take into account its disadvantages:
- compliance with safety rules is required;
- limitation in use depending on the stage of vegetation;
- has only a preventive effect.
Application procedure
Fungicide Kuproksat is used to prepare a working solution. Its concentration depends on the type of cultivated crop. The solution requires enamel, glass or plastic dishes.
First, a measured amount of the drug Cuproxat 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 fine atomizer spray.
Apple tree
With high humidity, the apple tree can suffer from scab. This is a fungal disease that affects young shoots, leaves and ovaries. Swamp spots appear on them, which gradually darken and lead to the formation of cracks.
To protect the apple tree from scab, a solution is prepared based on the fungicide Cuproxat. According to the instructions for use, for the treatment of 1 hundredth 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 Cuproxat is performed when the buds open. 3 weeks before harvesting apples, all treatments are stopped.
There are apple varieties that are sensitive to copper-based fungicides. After their processing during the flowering period, a so-called "grid" is formed on the leaves and fruits.
Stone fruit crops
Peach, apricot and other stone fruit crops are susceptible to diseases such as moniliosis, leaf curl, and clusterosporiosis. Diseases spread quickly and result in 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 sprays with the Kuproksat solution. Between procedures, they are kept from 7 to 10 days. The last spraying is carried out 25 days before harvest.
For 10 liters of water, according to the instructions for use, 45 ml of suspension is added to the fungicide Cuproxat. The resulting solution is sufficient to process 1 weave of an orchard.
Grapes
A dangerous disease of grapes is mildew. The disease is fungal in nature and is diagnosed by the presence of white bloom on the shoots and leaves. As a result, grape leaves die off, plant immunity decreases and its yield decreases.
Preventive treatments help to avoid the development of the disease. During the growing season, plantings are sprayed with a solution of the drug Kuproksat. According to the instructions for use, 6 ml of concentrate is required for 1 liter of water. The prepared solution is consumed for 10 sq. m vineyard.
Potatoes
In the second half of summer, signs of late blight may appear on potatoes. The causative agent of the disease is a fungus that infects the shoots and tubers of potatoes. Late blight is determined by the presence of brown spots covered with a grayish bloom. The affected parts of the bush die off, in advanced cases, plantings die.
Another dangerous disease of potatoes is Alternaria, which looks like dry gray-brown spots. The defeat spreads to the leaves, which turn yellow and die off, gradually passes to the tubers.
Protective measures are carried out after planting potatoes. During the season, plantings can be treated with Cuproxat three times, but not more often than once every 10 days.
The solution for spraying is prepared according to the instructions for use of the drug Cuproxat. 10 water requires 50 ml of suspension. The prepared solution is enough to process 1 hundred square meters of plantings.
Precautions
Fungicide Kuproksat has been assigned a hazard class 3 for humans and bees. If there is an apiary nearby, then it is allowed to release bees 12-24 hours after spraying the plantings.
The active ingredient of the fungicide Kuproksat is dangerous for fish and other aquatic organisms. Processing is carried out at a distance from water bodies, rivers and other similar objects.
For spraying plants, choose the morning or evening time, when there is no direct sunlight, rain and strong wind.
It is important to avoid contact of the solution with the skin and mucous membranes. In case of contact with open areas, rinse them with frequent water.
In case of poisoning with Kuproksat, the victim is given 2 glasses of clean water and 3 sorbent tablets (activated carbon) to drink. Be sure to seek medical help.
Fungicide Cuproxat is stored in a dry place at temperatures above 0 ° C. The product is kept away from children, animals, food and medicines.
