Embodiment 1

[0061] The present invention contains the emulsifiable concentrate preparation of the efficient insecticide of cypermethrin, thiamethoxam and bifenthrin, and concrete composition is as follows (every part 1000g):

[0062] Cypermethrin: 10 parts; Thiamethoxam: 20 parts; Bifenthrin: 20 parts;

[0063] The specific production steps of the emulsifiable concentrate preparation are first adding the active ingredients cypermethrin, thiamethoxam, 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 transparent oily liquid , filling, the emulsifiable concentrate preparation of the composition of the present invention can be made.

Embodiment 2

[0065] The present invention contains the suspending agent of the efficient insecticide of cypermethrin, thiamethoxam and bifenthrin, and concrete composition is as follows (every part 1000g):

[0066] Cypermethrin: 50 parts; Thiamethoxam: 40 parts; Bifenthrin: 60 parts;

[0067] 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, thiamethoxam 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 then the suspension agent of the composition of the present invention can be made preparation.

Embodiment 3

[0069] The present invention contains the water-dispersible granule of the high-efficiency insecticide of cypermethrin, thiamethoxam and bifenthrin, and the specific composition is as follows (every part of 1000g):

[0070] Cypermethrin: 35 parts; Thiamethoxam: 30 parts; Bifenthrin: 40 parts.

[0071] The specific production steps of this water-dispersible granule are the conventional preparation methods of water-dispersible granules in the art: according to the above formula, the active ingredients cypermethrin, thiamethoxam, bifenthrin, dispersant, wetting agent, disintegrating agent and The filler is mixed evenly, pulverized with an ultra-fine jet mill, kneaded, and then added to a fluidized bed granulation dryer for granulation, drying, and sieving. After sampling and analysis, the water-dispersible granules of the composition of the present invention can be prepared. agent.

Abstract

The invention relates to a high efficiency pesticides composition used for killing agricultural insects, which comprises the following components by weight: 10-50 parts of cypermethrin, 20-40 parts of thiamethoxam and 20-60 parts of bifenthrin. The insecticidal composition has obvious synergy effect, and is capable of reducing amount of active components, reducing usage cost, delaying the generation of insect resistance, and effectively reducing environment pollution and pesticide residues, and has obvious effect for killing insects such as oriental tobacco budworm, cotton bollworm, diamondback moth, beet armyworm, prodenia litura, tea geometrid, pink bollworm, aphid, Liriomyza sativae Blanchard, beetle, stinkbug, phylloxera, thrips, Leguminivora glycinivorella, Homona magnanima, caterpillar, slug moth, Phyllocnistis citrella Stainton and Ceroplastes rubens Maskell; and thereby the environment destroy can be reduced.
