Balcony container vegetables will also have bugs, if insects are found, it is necessary to distinguish whether it is water, light, temperature and other environmental conditions or matrix fertility problems. After excluding these factors, it is determined whether it is a disease or an insect pest. The following editor will teach you how to diagnose vegetable pests.

The diagnosis method of vegetable diseases and pests can be identified by the morphological characteristics of pests in different periods, or by the residue of insect pests. The residues of pests such as eggshell, pupa shell, peeling, residual hair and dead bodies, as well as feces, honeydew, silk mesh, foam and so on.

If it is found that there are fresh pest feces on or around the vegetable plant and fresh insect mouth on the vegetable plant, it can be judged that the pest is harmed far away in the vegetable. Sometimes, although there are feces and insect population, but the feces and insect population have dried up, indicating that the pest has moved to other places. Most of these pests are moth pests and larvae.

Such as potatoes, onions, garlic and other underground roots in the growth and storage rot or be eaten, such as nose worms, root mites and so on.
