What plants can be processed
This fungicide is intended for preventive treatment of trees and shrubs. However, the preparation of the plant does not cure. Therefore, if the fungus has already entered the leaves and fruits, it will be ineffective.
The tool helps well in the fight against scab and various types of spots on trees. And also apple and pear trees are sprayed with copper sulfate against coccomycosis, moniliosis and spotting. Garden roses and shrubs will be free of spots and powdery mildew.
Among berry crops, not all bushes can be treated with the product, but only currants and gooseberries.
Features of using the drug
For preventive purposes, vitriol must be used twice a year. Plants are processed as follows:
- Late autumn (late October or mid November).
- Early in spring (before bud swelling).
Autumn processing of horticultural crops is considered the most effective. The plant should be treated most carefully at the point of attachment of skeletal cells to the tree trunk.
It is undesirable to mix copper sulfate with other means.
The consumption of the drug is from 2 to 10 liters of the working solution. It is advisable to use it in the morning or late at night. To treat new wounds, increase the concentration to 3%.
Correct dilution of copper sulfate
The drug should be diluted in an enamel or glass container. It is better not to use iron because of the rapid interaction of vitriol with metal.
The finished solution cannot be stored. It should be used immediately after dilution. To help the crystals dissolve faster, it is recommended to use warm water. Dilute the required amount of the drug in it, then add water to obtain the required concentration of 1% or 3%.
Bring the solution to 10 l of water (100 g of vitriol at a concentration of 1%). Strain it through cheesecloth or bandage before starting work, otherwise the sprayer will clog.
Precautions
Copper sulfate does not pose a danger to human and animal health. But when working with it, you should remember about precautions and make sure that the drug does not get on the skin and eyes. To do this, put on a robe, gloves and glasses.
