Chemical prevention and control method for rape flea beetles

Abstract

The present invention discloses a chemical prevention and control method for rape flea beetles. The method comprises: 1, preparing pesticide, 2, carrying out a coating seed dressing treatment on seeds, 3, selecting a test field and sowing the coating seeds, and 4, carrying out investigation and mathematical statistics on the prevention and control effect. According to the present invention, the field test method is adopted to screen the chemical agent for effectively preventing and controlling rape flea beetles, test results show that prevention and control effects of the fipronil.imidacloprid auxiliary agent B on flea beetles in different regions are significantly higher than prevention and control effects of other agents, significant increase effects can be provided for insect disinfestation activity of pesticides with the auxiliary agent B, and the fipronil.imidacloprid has significant production application values under the effect of the auxiliary agent B. In addition, the operations are simple, and problems of drug resistance, farmland ecology environment reduction and damage, human and animal poisoning and other secondary poison of flea beetles can be solved.

Description

technical field [0001] The invention belongs to the technical field of prevention and control of agricultural diseases and insect pests, and in particular relates to a chemical control method of rape flea beetle. Background technique [0002] In recent years, the planting area of ​​spring rape in Qinghai Province has gradually increased. As of 2010, the planting area reached about 3 million mu. Now it has become one of the main economic crops in Qinghai Province. Under the influence of various factors such as environment and man-made, the old pests in spring rapeseed fields have become more harmful, such as flea beetle, stalk weevil, rhododendron beetle and diamondback moth. Among them, the rape seedling pests, flea beetle directly affect the emergence of rapeseed and the yield of rapeseed. Flea beetles belong to the order Coleoptera and Chrysophyllidae. Phyllotreta striolata (Fabricius) and yellow broad flea beetle (Phyllotreta hμmilis Weise) are more numerous. Adults dama...
