Timely elimination of shell insects, aphids and other pests can reduce the occurrence of soot disease. Grey spot disease, soot disease and root rot of camellia are more common.

Camellia disease control methods, when the quantity is small, the mildew layer can be gently scrubbed with clean water; when the quantity is large, 50% carbendazim 500-800 times solution can be sprayed to control. Timely elimination of shell insects, aphids and other pests can reduce the occurrence of soot disease.

The occurrence of camellia gray spot, soot and root rot is more common.

1. Camellia gray leaf spot: this disease mainly harms leaves and tender shoots. After the injury of the leaves, irregular dark brown disease spots appeared, and then large gray-white disease spots were formed. In the later stage of the disease, some disease spots ruptured from the leaf surface to shedding to form perforation. New shoots often fall off from the base after being damaged, so florists call it "disjoint disease".

2. Soot disease: also known as coal fouling disease, black mildew. At the initial stage of the disease, black mildew spots appeared on the leaves and branches, and then gradually expanded and spread the whole leaves or branches, making the leaves form a closely covered soot layer, hindering photosynthesis, weakening the growth potential and affecting the ornamental. Soot disease is easy to occur in the environment of high temperature, high humidity and poor ventilation. The disease is often accompanied by plants damaged by shell insects, aphids and so on.

3. Root rot: Camellia root rot is caused by soil fungi, cinnamon. Torture plants stop growing. The leaves of the plant turn yellow, then turn grayish green, wither and fall off. The roots of plants vary from healthy white to reddish brown or dark brown. The rotting root is unable to pick up water, and the factory eventually dies of dehydration. The fungus inflates the soil with poor drainage and lack of funds.

Prevention and control methods of camellia diseases:

① put the flowerpot in a ventilated and transparent place to avoid damp and stuffy environment.

② can reduce the occurrence of soot disease by eliminating shell insects, aphids and other pests in time.

When the amount of ③ is small, the mildew layer can be gently scrubbed with clean water; when the quantity is large, 50% carbendazim 500,800 times solution can be sprayed to prevent and cure.
