Embodiment 1

[0051] The present invention contains the emulsifiable concentrate preparation of the high-efficiency insecticide of fenvalerate, fipronil and chlorpyramid, and concrete composition is as follows (every part 1000g):

[0052] Fenvalerate: 10 parts; Fipronil: 20 parts; Toxochlor: 20 parts;

[0053] The specific production steps of the emulsifiable concentrate preparation are first adding the active ingredients fenvalerate, fipronil, and chlorpyridone into the solvent according to the conventional procedures in the field to completely dissolve them, then adding emulsifiers and synergists and stirring evenly to form a uniform transparent oil The liquid can be filled into an emulsifiable concentrate preparation of the composition of the present invention.

Embodiment 2

[0055] The present invention contains the suspending agent of the high-efficiency insecticide of fenvalerate, fipronil and chlorpyramid, and concrete composition is as follows (every part of 1000g):

[0056] Fenvalerate: 50 parts; Fipronil: 40 parts; Toxochlor: 60 parts;

[0057] 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 fenvalerate, fipronil and chlorpyrid, 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 of the composition of the present invention can be made. formulations.

Embodiment 3

[0059] The present invention contains the water dispersible granule of the high-efficiency insecticide of fenvalerate, fipronil and chlorpyramid, and concrete composition is as follows (every part 1000g):

[0060] Fenvalerate: 35 parts; Fipronil: 30 parts; Toxochlor: 40 parts.

[0061] 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 fenvalerate, fipronil, chlorpyramid, dispersant, wetting agent, disintegrant And the filler is mixed uniformly, pulverized with an ultrafine jet mill, kneaded, and then added to a fluidized bed granulation dryer for granulation, drying, and sieving. After sampling and analysis, the water dispersion of the composition of the present invention can be made. granules.

Abstract

The invention relates to an efficient insecticide composition for killing agricultural pests. The efficient insecticide composition comprises the following components in parts by weight: 10-50 parts of fenvalerate, 20-40 parts of fipronil and 20-60 parts of chlorfenvinphos. The efficient insecticide composition disclosed by the invention has a remarkable synergetic effect, is capable of reducing the consumption of active ingredients, lowering the use cost, delaying the generation of pest resistance to insecticides, and effectively reducing the environment pollution and pesticide residue, and has a remarkable effect of killing pests such as cotton bollworm, cabbage caterpillars, oriental tobacco budworm, tea hair-4 bean-pod borer, noctuid moths, budworm, leaf miner, pyralid moths, caterpillars, slug caterpillar moths, inchworm, cotton geometrid, phytophthira, leafhoppers, plant hoppers, stinkbug, locusts and leaf-eating coleopteran; meanwhile, the damage to the environment can be reduced.
