Grape blight is one of the most important diseases of vineyards and vineyards. Grape blight is a fungal disease caused by a fungal attack and can be very damaging if left unchecked. The grape tree that is infected with this disease produces weak and dull grapes and low quality grapes that will not have a good market for sale. Signs of contamination of vineyards and orchards include white dust on the leaves and seeds of grapes and grapes, as well as gray spots on the stems and branches. This disease weakens and withers the grape tree and reduces its yield. Sefidak attacks different parts of the grape. It leaves gray spots on grape stems and clusters, as well as grayish white pollen on the leaves. This fungal disease, as mentioned, causes a lot of damage to the vine.
Because grapefruit is a fungal disease, it is more common in environments with low light and high humidity. Atmospheric agents such as wind or even animals and humans gradually transfer the fungal white granules to other hair trees and contaminate them. Various fungicides can be used to treat gray hair, but the easiest way is to use sulfur. The method of using sulfur is that after germination and the emergence of several leaves on the branches, about 100 grams of micronized powdered sulfur is used per 100 square meters of vineyard surface.
Sulfur spraying can be done manually or using a sprayer. The second stage of sulfur spraying on the surface of hair gardens is after flowering, in this stage 250 grams of micronized sulfur is used. Two weeks after the second stage, the third stage of sulfur spraying is done. Finally, when the best seeds grow, the last stage of sulfur spraying is done. At this stage, about 400 grams of micronized powdered sulfur per 100 square meters of vineyard is used.
