Black Master's Pest Control

Main disease: Leaf spot

This disease mainly harms the leaves, and it spreads very quickly, through air currents, rain and other means. It can also overwinter on the surface of the soil and revive the following year to harm succulents. This disease may occur throughout the year, but the most serious period is from August to September, when the temperature is higher. If the air in the breeding environment is not flowing and it is relatively humid on rainy days, this problem is very likely to occur.

Prevention and treatment methods

Improve the environment, strengthen the flow of gas, avoid water accumulation when supplying water, and do not allow the soil to be in an over-wet state for a long time. When the disease occurs, you can spray it with medicine and isolate it from other plants. Before winter, the diseased parts should be removed, the fallen leaves should be cleaned up, and the soil can be turned over appropriately. Reduce the chance of diseases overwintering on the soil surface.

Main pests: Black weevil

When this pest occurs, it will seriously affect the ornamental value of the plants. They eat the leaves of the plants to survive. In severe cases, it may cause other problems.

Prevention and treatment methods

When there are small quantities, they can be captured manually or killed by spraying with drugs. In severe cases, the entire plant must be destroyed.
