Abstract

The present invention relates to the compounding method of pesticide, and is especially the compounding of pesticide with nimbin and some miticide as main material. In the mixed pesticide, the synergistic effect of nimbin and miticide replenish each other to overcome the resistance of mite, raise the application effect of the pesticide and prolong its acting period.

Description

technical field [0001] The invention belongs to the compounding of pesticides and a preparation method thereof, in particular to the compounding of azadirachtin and acaricides. Background technique [0002] At present, chemical acaricides are mostly used in the prevention and control of agricultural pest mites, which can easily cause pest mites to develop drug resistance, kill a large number of beneficial natural enemies, lead to rampant damage of pest mites, pollute the environment, and easily cause human and animal poisoning. Therefore, the development of environmentally friendly acaricides is an urgent need for agricultural production. [0003] Azadirachtin is a compound derived from the plant Neem, which has excellent acaricidal activity, degrades quickly in the environment, and does not harm natural enemies and other non-target organisms. The disadvantage is that it is unstable and has fewer processed dosage forms. [0004] The purpose of the ...
