Embodiment 1

[0048] The present invention contains the emulsifiable concentrate preparation of the high-efficiency insecticide of fenitrothion, pyridaben and methoprene, and the specific composition is as follows (1000g per part):

[0049] Fenitrothion: 10 parts; Pyridaben 20 parts; Methoprene: 20 parts;

[0050] The specific production steps of the emulsifiable concentrate preparation are first adding the active ingredients fenitrothion, pyridaben, and methoprene into the solvent according to the conventional procedures in this field and completely dissolving them, 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

[0052] The present invention contains the suspending agent of fenitrothion, pyridaben and the high-efficiency insecticide of methoprene, and concrete composition is as follows (every part 1000g):

[0053] Fenitrothion: 50 parts; Pyridaben: 40 parts; Methoprene: 60 parts;

[0054] 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 fenitrothion, pyridaben and methoprene, 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

[0056] The present invention contains the water dispersible granule of fenitrothion, pyridaben and the efficient insecticide of methoprene, and concrete composition is as follows (every part 1000g):

Abstract

The invention relates to an efficient pesticide composition for killing agricultural pests. The pesticide composition comprises the following components in parts by weight: 10-50 parts of fenitrothion, 20-40 parts of pyridaben and 20-60 parts of hydroprene. The pesticide composition disclosed by the invention has the advantages that the pesticide composition has an obvious synergistic effect, and is capable of reducing dosages of active ingredients, lowering usage cost, delaying disease resistance of pests and effectively reducing environmental pollution and pesticide residue; the pesticide composition has an obvious killing effect on such pests as pink rice borer, striped rice borer, tryporyza incertulas, rice planthopper, rice leafhopper, aphid, red spiders, cotton bollworm, soybean pod borer and tea geometrid; meanwhile, the pesticide composition can lower damage to environment.

Description

technical field [0001] The invention relates to the field of insecticides used for the control of agricultural pests, in particular to a high-efficiency insecticide containing fenitrothion, pyridaben and methoprene. Background technique [0002] The residues of pesticides in agricultural products and the toxicity to animals have always been a hot spot of concern. [0003] Fenitrothion: [0004] Chinese aliases: Fenotsong, Sumisong, Nuobi Sumisong [0005] English name: fenitrothion [0006] English aliases: O, O-dimethyl O-4-nitro-m-tolyl phosphorothioate; O, O-dimethyl O-(3-methyl-4-nitrophenyl) phosphorothioate; [0007] Chemical name: O, O dimethyl-0-(3-methyl-4-nitrophenyl) phosphorothioate [0008] CAS number: 122-14-5 [0009] Molecular formula: C9H12NO5PS [0010] Molecular weight: 277.234 [0011] Structural formula: [0012] [0013] Fenitrothion is stable to light, and it is easy to decompose and fail when exposed to high temperature. It is hydrolyzed in...
