Problems solved by technology

Although chemical control has the characteristics of easy operation and remarkable control effect, it also causes great harm while killing pests. First, the increased resistance of pests makes control increasingly difficult; Toxicity and biomagnification, chemical poisons are enriched in the human body through the food chain, causing harm to humans

Abstract

The invention provides an interference repellent for leguminivora glycinivorella, and also discloses a preparation method for the interference repellent. The interference repellent is prepared from leaf alcohol, cis-3-hexenyl acetate, cis-3-hexenyl ester n-valerate, (E)-butyric acid-3-hexenyl ester, ocimenum, (Z)-propionic acid-3-hexenyl ester, alpha-farnesene, methyl jasmonate, n-hexane or dimethylbenzene and the like. The interference repellent has reasonable components, is an environment-friendly biological interference repellent, has a simple preparation method and a good prevention and control effect, is safe for crops and natural enemies, cannot make insects generate resistance, is environment-friendly and convenient to apply and popularize, and has a wide market prospect and obvious economic, ecological and social benefits.

Description

technical field [0001] The invention provides a soybean borer interference repellant and discloses a preparation method thereof, belonging to the technical field of pesticide production. Background technique [0002] Soybean borers occur all the year round in my country's Huanghuai summer soybean region and Northeast soybean producing areas, causing serious damage. In normal years, the insect-eating rate is 15-30%, and the yield is reduced by 5-10%. In severe years, the insect-eating rate can reach 50-70%, and the yield is reduced by 20%. -40%, its harm is one of the main reasons for the reduction of soybean quality and production. Therefore, the prevention and control of soybean borer has also become one of the important links in soybean production. [0003] At present, the control of soybean borer is still dominated by chemical control, that is, the leaves and pods are sprayed with pyrethroids such as lyfelin and quick-killing thalin before the adult stage and the larval h...
