When it suffers from anthrax, it is mainly injured in the leaves. At the beginning of the disease, some irregular brown disease spots appear on its leaves, and then as time goes on, these leaves will slowly turn gray-white. And there are a lot of small black spots on the spot. It not only affects the growth of the plant, but also greatly affects its beauty.

The pattern of the disease is that the mycelium stays on the diseased leaves for the winter, and then when they wait until next spring, they continue to produce spores, followed by the transmission of wind and rain, causing the disease. The disease is usually more likely to occur in muggy weather and, in severe cases, can scorch or fall off all the leaves of the plant.
