Embodiment 1

[0049] The present invention contains the emulsifiable concentrate preparation of the high-efficiency insecticide of azadirachtin, cyphenthrin and perfenthrin, and concrete composition is as follows (every part 1000g):

[0050] Azadirachtin: 10 parts; phenthrin: 20 parts; perbromethrin: 20 parts;

[0051] The specific production steps of the emulsifiable concentrate preparation are first adding the active ingredients azadirachtin, cyphenthrin, and perfenthrin into the solvent according to the conventional procedures in the field to completely dissolve, then adding emulsifiers and synergists and stirring evenly to form a uniform and transparent The oily liquid can be filled into the emulsifiable concentrate preparation of the composition of the present invention.

Embodiment 2

[0053] The present invention contains the suspending agent of the high-efficiency insecticide of azadirachtin, cyphenthrin and perfenthrin, and the specific composition is as follows (every part of 1000g):

[0054] Azadirachtin: 50 parts; phenthrin: 40 parts; perbromethrin: 60 parts;

[0055] The specific production steps of this suspending agent are the conventional suspending agent preparation method in the art, first other auxiliary agents (dispersant, antifreeze agent, thickener, defoamer, penetration enhancer and pH value regulator) are mixed, Shear and mix evenly, add active ingredients azadirachtin, cyphenthrin and perbromethrin, and grind the balls in a ball mill for 2 to 4 hours, so that the particle diameters are all below 5mm, and the composition of the present invention can be prepared suspension formulations.

Embodiment 3

[0057] The present invention contains the water-dispersible granule of the high-efficiency insecticide of azadirachtin, cyphenthrin and perfenthrin, and the specific composition is as follows (every part of 1000g):

[0058] Azadirachtin: 35 parts; cyphenthrin: 30 parts; perbromethrin: 40 parts.

[0059] The specific production steps of the water-dispersible granules are the conventional preparation methods of water-dispersible granules in the art: according to the above formula, the active ingredients azadirachtin, cyphenthrin, perfenthrin, dispersant, wetting agent, disintegrant The solution and the filler are mixed evenly, pulverized with an ultra-fine jet mill, kneaded, then added to a fluidized bed granulation dryer for granulation, drying, and sieving. After sampling and analysis, the composition of the present invention can be prepared. Water dispersible granules.

Abstract

The invention relates to a high-efficient pesticide composition which is composed of following components, by weight, 10-50 parts of azadirachtin, 20-40 parts of cyphenothrin and 20-60 parts of tralomethrin. The pesticide composition has a significant synergistic effect, can reduce a use amount of effective components and a use cost, can delay generation of the resistance in the pests, can effectively reduce environmental pollution and pesticide residue, and has significant killing effects on almost all plant pests, indoor pests, fleas, flies, mosquitoes and the like. Meanwhile, the pesticide composition is reduced in damage on environment.
