Abstract

The invention discloses an anti-mite composition containing pyriminostrobin. The anti-mite composition containing pyriminostrobin comprises active ingredients A and B, wherein the active ingredient A is pyriminostrobin, the active ingredient B is any one compound of bifenazate, hexythiazox, spirodiclofen, fenpyroximate and bromopropylate, and weight ratio of the active ingredient A to the active ingredient B is (1 to 80) - (60 to 1). The anti-mite composition containing pyriminostrobin has synergistic effect on multiple pest mites damaging agricultural production, usage amount of pesticide is reduced, residual quantity of the pesticide on crops is reduced, environmental pollution is reduced, the anti-mite composition is safe to people and livestock, environmental compatibility is good, and the pest mites hardly produce insecticide resistance.

Description

[0001] This application is a divisional application. The original application was submitted by Shaanxi Thompson Biotechnology Co., Ltd. for a patent titled: "An Acaricidal Composition Containing Pyrimimethan". The application number is: 201210591603.4, and the application date is: 2012.12.29 technical field [0002] The invention belongs to the technical field of pesticides, and relates to the application of an acaricidal composition containing pyrimidazan on crop pest mites. Background technique [0003] Pyriminostrobin chemical name: 2-tert-butyl-5-(4-tert-butylbenzylthio)-4-chloropyridazin-3(2H)-one, molecular formula: C 23 h 18 C l2 f 3 N 3 o 4 . The agent has a good control effect on Panonychus, spider mites, adults, nymphs, and larvae, and exhibits excellent ovicidal activity. [0004] Molecular formula of Bifenazate: C 17 h 20 N 2 o 3 . It is a novel selective foliar spray acaricide effective against all life stages of mites. It has ovicidal activity and r...
