Embodiment 1

[0042] The present invention contains the emulsifiable concentrate preparation of the high-efficiency insecticide of cypermethrin, phoxim, cyromazine and thiofluoroxime, and the specific composition is as follows (1000g per part):

[0043] Cypermethrin: 20 parts; Phoxim: 30 parts; Cyromazine: 10 parts; Thiofluoroxime: 20 parts;

[0044] The specific production steps of the emulsifiable concentrate preparation are first adding the active ingredients cypermethrin, phoxim, cyromazine and thiofluoroxime ether into the solvent according to the conventional procedures in this field to completely dissolve, then adding emulsifiers and synergists and stirring evenly to form a uniform The transparent oily liquid can be filled into an emulsifiable concentrate preparation of the composition of the present invention.

Embodiment 2

[0046] The present invention contains the suspending agent of cypermethrin, phoxim, cyromazine and the high-efficiency insecticide of thiofluoroxime ether, and concrete composition is as follows (every part 1000g):

[0047] Cypermethrin: 50 parts; Phoxim: 60 parts; Cyromazine: 40 parts; Thiofluoroxime ether: 40 parts;

[0048] 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 effective ingredients cypermethrin, phoxim, cyromazine, and thiofluoroxime ether, and grind the balls in a ball mill for 2 to 4 hours, so that the particle diameters are all below 5mm, and the combination of the present invention can be made suspension formulations.

Embodiment 3

[0050] The present invention contains the water-dispersible granule of the high-efficiency insecticide of cypermethrin, phoxim, cyromazine and thiofluoroxime, and the specific composition is as follows (1000g per part):

[0051] Cypermethrin: 35 parts; phoxim: 45 parts; cyromazine: 25 parts; thiofluoroxime ether: 30 parts.

[0052] 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 cypermethrin, phoxim, cyromazine, thiofluoroxime ether 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 an efficient insecticide composition used for killing agricultural insects. The efficient insecticide composition is composed of the following components in parts by weight: 20-50 parts of cypermethrin, 30-60 parts of phoxim, 10-40 parts of cyromazine, and 20-40 parts of sulfur-fluorine oxime ether. The efficient insecticide composition has the advantages of wide insecticidal spectrum, strong killing force and no systemic action; the efficient insecticide composition is decomposed rapidly since the efficient insecticide composition is unsteady under lights in a field, so that the residual period is short, and the residual risk is low; the efficient insecticide composition has outstanding killing effects on plutella xylostellas, asparagus caterpillars, cotton bollworms, striped rice borers, mealybugs and flies which mainly include liriomyza sativae, liriomyza huidobrensis, melanagromyza sojae, liriomyza chinensis and liriomyza trifolii.
