Common diseases and pests of Chinese evergreen and their control methods

Diseases of Proteaceae

There are fewer diseases of evergreen, the main ones are ring spot disease, stem rot disease, etc.

When evergreen is infected with ring spot disease, ring-shaped necrotic spots will appear on the leaves, causing the leaves to twist, the plant to grow slowly or rot and not grow, and it will not bloom. Bordeaux liquid can be sprayed regularly for prevention and control.

When Chinese evergreen is infected with rhizome rot, black spots will not appear on the rhizome and it will gradually rot. In addition, the symptoms of scab infection on evergreen are basically the same as those on rot. Spray with 1000 times diluted 50% carbendazim wettable powder.

Peacock Green Pests

Common pests include scale insects and slugs.

Let me first talk about slugs, which look like snails without shells. This disease rarely occurs in home breeding. Once it appears, it will drill into the leaves of the plants, causing the plants to wither. There are rumors that sprinkling salt on them can kill them, so you can give it a try.

Scale insects are common pests in home-grown Chinese evergreens and are more likely to occur in hot and humid environments. When the disease occurs, the insects will attach to the leaves, suck the sap, and cause the plant to wilt. When the disease occurs, you can spray omethoate solution, or you can spray disinfectant in advance to prevent the disease from happening.
