Abstract

The invention belongs to the technical field of compounding pesticides, and specifically relates to water dispersible granules containing tebufenpyrad and an application of the water dispersible granules. The weight ratio of tebufenozide to tebufenpyrad is 15:1-1:15. Compared with a pesticide with a single component, the water dispersible granules have the advantages that the pest resistance to insecticide is delayed, the effective active control spectrum is expanded, and the effect is remarkably improved, so that the use level of the pesticides is reduced, the influence on the environment is reduced and the pesticide residue is reduced while the pesticide cost of farmers is lowered.

Description

technical field [0001] The invention belongs to the technical field of compounding pesticides and insecticides, and specifically relates to a water-dispersible granule containing tebufenpyrad and its application. Background technique [0002] Tebufenpyr [0003] English name: Tebufenpyrad [0004] Molecular formula: C18H24CLN3O [0005] CA registration number: 119168-77-3 [0006] Chemical name: N-(4-tert-butylbenzyl)-4-chloro-3-ethyl-1-methylpyrazol-5-ylcarboxamide [0007] Melting point (°C): 61~62 [0008] Vapor pressure: 0.010787mPa (40°C) [0009] use: [0010] This product is an amide acaricide. It has excellent effects on various mites and pests of Hemiptera and Homoptera, and Dan has quick-acting and high-efficiency effects on all growth stages of mites, and has a long-lasting effect. [0011] However, its effect is also very single, and the risk of resistance after large-scale application is also very high. [0012] tebufenozide [0013] English common nam...
