A kind of auxiliary agent and its application in the preparation of thrips control medicament

Abstract

An auxiliary agent for improving the control effect of thrips is composed of glucose, sucrose and fructose. The additive has a broad-spectrum attracting effect on different thrips, and the attracting rate reaches more than 99%. It can be used to lure thrips alone and then kill them, or it can be directly killed together with insecticides. Affected, it has excellent stability, and the mixed use with emaminil benzoate reduces the frequency of use of chemical agents, and has excellent and stable control effect.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to an adjuvant and its application in preventing and treating thrips. Background technique [0002] Thrips is a general term for Thysanoptera insects. There are about 6,000 known species in the world, and 600 species in China. They are harmful to various plants such as melons and fruits, vegetables, rice, cotton, mangoes, and strawberries. Thrips feed on adults and nymphs. Suck the juice of young plant tissues (twigs, leaves, flowers, fruits, etc.), the damaged young leaves and shoots become hard, curl and wither, fall off, and the plant grows slowly; flower organs drop early, and young fruits (such as eggplant, cowpea, etc.) After being killed, it will harden and shrink, and in severe cases, it will cause fruit drop, which will seriously affect the yield and quality. [0003] At present, there have been many studies on thrips control at home and abroad, and the control metho...

Problems solved by technology

However, thrips has the characteristics of fast reproduction, many algebras, and good flying and jumping properties. At the same time, its harmful parts are hidden, mainly hiding in flowers, and cannot be directly contacted by spraying drugs, which increases the difficulty of control. Difficult-to-control pests of pepper, cowpea, etc.

In order to effectively control the harm of thrips, chemical pesticides are often used frequently, resulting in excessive pesticide residues and seriously affecting the quality of vegetables

In actual production, farmers use 0.3% brown sugar combined with insecticides to improve the killing effect of thrips, but the effect is extremely unstable. The specific performance is that sugar has a large difference in the attracting effect of different types of thrips, which is not ideal. The attracting effect is inhibited after mixing, resulting in the loss of the auxiliary effect
