Summer diamondback moth, cabbage caterpillar, Spodoptera litura, etc., often occur in vegetables, can be used to prevent and control the following technical measures.

I. Insect net isolation technology: Insect net isolation can effectively control the pests of Plutella xylostella, Spodoptera litura, Pieris rapae, aphids and other insect pests, with or without pesticides, is an effective pollution-free vegetable production technology. The 22-mesh silver-gray insect-proof nets should be used for isolation and cultivation in the production. The application techniques are as follows: 1. Soil drying before covering the net can kill part of the underground pests; 2. When the nets are covered, the perimeter of the insect-proof nets should be tightly compacted. To prevent pests from sneaking into spawning. 3. Treat the soil with muscat before sowing or transplanting to kill the pests and eggs that remain in the soil. 4. During the isolation of insect nets, try to minimize the number of nets to avoid adult insects from flying in, and pay attention to the timely removal of production. The egg blocks on the mesh yarn; 5. In sunny hot weather, it is easy to cause high temperature in the shed, and the cooling measures such as shading and irrigation should be adopted.

Second, sex pheromones, swatches, insect traps kill: can effectively control the development of pests, reduce the number of pests, reduce the number of field chemicals control.

Third, the chemical control: the prevention and treatment must pay attention to safe medication, do not use banned pesticides, to use biological pesticides and high efficiency and low toxicity and low residual pesticides, and strictly enforce the safety interval. With 10% imidacloprid wettable powder 10-20 grams or 5% imidacloprid cream 20-40 ml plus 800 times the new high-fat membrane control aphids. 10% chlorfenapyr EC plus a new high-fat membrane 800 times control of diamondback moth, cabbage moth.

Fungi, a large class of chlorophyll - free, can not carry out photosynthesis, heterotrophic lower class of plants. These include bacteria, slime molds and fungi. Their common characteristics are: the plant body has no differentiation of roots, stems and leaves, does not contain chlorophyll and other photosynthetic pigments (except a few photosynthetic bacteria), can not carry out photosynthesis, saprophytic life or parasitic life, that is, heterotrophic life. Most of the reproductive organs are single-cell structures, and the zygotes do not develop into embryos.
