Soil pollution

Symptoms of Sooty Disease

Sooty mold disease mainly attacks leaves. In the early stage of the disease, it is distributed like soot spots, and later it will gradually cover the entire leaf, causing the leaf to crack and peel off. Sooty mold fungi mainly parasitize on the excrement and secretions of aphids, scale insects, etc., and are prone to disease under conditions of high temperature, high humidity and poor ventilation.

Coal pollution prevention and control

Aphids and scale insects should be killed promptly; plants should be pruned to allow ventilation and light; carbendazim, methyl thiophanate and other drugs can be sprayed to prevent and control sooty mold disease.
