Embodiment 1

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

[0050] Bifenthrin: 10 parts; Hydrazone: 20 parts; Bifenthrin: 20 parts;

[0051] The specific production steps of the emulsifiable concentrate preparation are first adding the active ingredients bifenthrin, hydrazone and bifenthrin 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 The transparent oily liquid can be filled into an 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 bifenthrin, hydrazone and bifenthrin, and the specific composition is as follows (every part of 1000g):

[0054] Bifenthrin: 50 parts; Hydrazone: 40 parts; Bifenthrin: 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 the active ingredients bifenthrin, hydrazone and bifenthrin, 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

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

[0058] Bifenthrin: 35 parts; Hydrazone: 30 parts; Flufenthrin: 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 bifenthrin, hydrazone, bifenthrin, dispersant, wetting agent, The disintegrating agent and the filler are mixed evenly, pulverized with an ultra-fine jet mill, kneaded, and then added to a fluidized bed granulation dryer for granulation, drying, sieving, and after sampling analysis, the composition of the present invention can be made water dispersible granules.

Abstract

The invention relates to an efficient pesticide composition for killing of agricultural pests, and the efficient pesticide composition comprises the following components by weight: 10-50 parts of bifenthrin; 20-40 parts of hydramethylnon; and 20-60 parts of flumethrin. The efficient pesticide composition has the advantages that: the efficient pesticide composition has obvious synergistic effect, can reduce the dosage of effective components, reduces the use cost, delays the development of pest drug resistance, effectively reduces the environmental pollution and pesticide residues, has obvious killing effects on tetranychus telarius linne, corn earworm, peach fruit borer, oriental fruit moth, tetranychus viennensis, panonychus citri mcg, erthesina fullo thunberg, halyomorpha halys, brevicoryne brassicae, cabbage caterpillar, plutella xylostella, tetranychus cinnabarinus, caloptilia theivora and other more than 20 insect pests, trialeurodes vaporariorum, tea geometrid, euproctis pseudoconspersa and other insect pests, and at the same time, can reduce the damage to the environment.
