1、 Rotavirus

Ring rot is one of the common diseases of Camellia. It mainly endangers the leaves of plants, with purplish red spots, and will expand slowly. When it infects the leaf veins, the disease will accelerate and deteriorate, leading to leaf wilting. It is usually caused by bacteria. Carbendazim solution can be sprayed for control before the high incidence period of the disease. In the early stage of the disease, the diseased leaves need to be cut off and sprayed

2、 Anthrax

Anthrax is harmful to many plants, including camellia. The disease mostly occurs from June to July. After the disease, brown spots will appear on the leaf tip or edge, and then spread to the whole leaf, or cause it to fall off. If you want treatment, you need to spray zineb solution at the early stage of the disease. At ordinary times, phosphorus, potassium or organic fertilizer should be applied to improve the disease resistance of plants

3、 Starscream

Red spider is one of the common pests. It is distributed in many places in China. It usually hatches in March and does serious harm in April. This pest sucks the juice of its camellia and causes it to grow poorly. In winter, we should do a good job in prevention and eliminate overwintering insect eggs. When the pest is serious, you can spray dicofol and other drugs to eliminate the pest

4、 Leaf curling moth

Leaf curling moth is also a common pest endangering camellia. It often occurs in spring and summer. Larvae will gnaw on new buds and other parts, resulting in leaf curling. Because adults like sugar and vinegar very much, they can be lured and killed. In addition, larvae can be eliminated by spraying Phoxim and other drugs, or by spraying trichlorfon solution
