What's going on with the grape leaves turning red
Grape leaves turn red mostly due to infection with cercospora leaf spot disease, which is relatively common and often occurs between July and September when the temperature is high and humidity is high, making it easy for pathogens to thrive. The disease mainly affects the leaves. Once detected, remove the diseased leaves promptly and burn them thoroughly to prevent infection of healthy branches and leaves. During management, ensure timely drainage, pruning, and good ventilation and lighting, as well as appropriately reducing humidity, which can reduce the incidence of the disease.
