Prevention method for flea beetles of pakchoi

Abstract

The invention discloses a prevention method for flea beetles of pakchoi. The prevention method includes setting up support frames, strapping encircling nets, applying pesticide to soil and seeding. The support frames are set up around vegetable beds, the encircling nets are put on the support frames and are buried and pressed in the soil, and a closed ring is formed in the field. The net barrier can effectively prevent the flea beetles from harming the pakchoi within the net barrier. The systemic-action-free pesticide is applied to the vegetable beds within the net barrier, so that flea beetle larvae and eggs in the soil within the net barrier can be killed. The prevention method is used for preventing and controlling the flea beetles, both internal and external factors are considered, both production and income are increased, and the prevention method is safe and environment friendly, simple and convenient to operate and easy to popularize.

Description

technical field [0001] The invention relates to the technical field of pakchoi plant protection, in particular to a method for preventing pakchoi flea beetle. Background technique [0002] Phyllotreta Vittata (Fabricius) belongs to the order Coleoptera, Chrysophyllidae, Leapaceae, and the genus Phyllotreta Vittata. It mainly harms cruciferous vegetables, especially Chinese cabbage, Chinese cabbage, mustard greens, and radishes. [0003] Chinese cabbage (Brassica rapa L. Chinensis Group.) is also known as green vegetables and rapeseed. Brassica genus Brassica, which has rich nutrition and high food value, is one of the important vegetable foods in people's daily life. [0004] Flea flea beetle is a major pest in the growth process of cabbage. Its harm is characterized by gnawing a large number of tiny holes on the leaves of cabbage, which not only hinders the growth of cabbage, reduces the yield of cabbage, but also affects the sales of cabbage. Relatively, the commerci...

Problems solved by technology

[0005] One of the important differences between pak choy and other vegetables is that the growth period is short, especially for pak choy in summer, it only takes more than 20 days from planting to harvesting. If the control of flea beetle is not effective, it will cause serious losses.

If pesticides are used for control, the short application interval will cause a large amount of pesticides to remain in the vegetables, causing major hidden dangers to human health.

Although the agricultural control of flea beetle has also been reported, most of them have not been popularized due to poor results.
