How to use it correctly
Black spot of roses and grapes
The disease is quite serious, so you should start treating crops immediately. You will need to prepare a spraying composition.

You will need to spray the crops with the following composition: mix a spoonful of liquid soap, any vegetable oil and soda in four liters of water. The product acts quickly and effectively.
