Early prevention and control of leaf mold in autumn tomatoes gives good results
Early blight: after the disease develops, concentric ring-patterned lesions appear on the leaf surface, dark brown and water-soaked. Before and after the disease appears, spray with a 500-fold dilution of 70% mancozeb wettable powder, or a 400-fold dilution of 75% chlorothalonil wettable powder, once every 7 days, for 3~4 consecutive sprays.
