1、 Cause

If the environment or method given during maintenance is improper, it is easy to cause pests, which will not only reduce the ornamental value, but also cause the death of the whole plant. Therefore, once found, measures should be taken to prevent and control. Of course, the measures taken or the drugs sprayed by different pests are different

2、 Solution

1. During the growth of beetles, it is most likely to cause beetles. It mainly erodes the main root and stem of the plant, resulting in incomplete plant growth. During treatment, Omethoate solution can be sprayed, and then the surface soil can be loosened to allow the solution to penetrate as soon as possible. Once touched, pests will die

2. Starscream: Starscream mainly endangers the leaves of the plant, which will cause the leaves to turn yellow or even fall. Remove the leaves of pests when they are found. If the affected area is large, spray dimethoate emulsion to eliminate it

3. Aphids: aphids do great harm to them, mainly on the back of the leaves, which will absorb the juice of the leaves, and finally lead to the death of the plant. When it is found, use anti aphid to control it in time, which can effectively kill pests
