Abstract

The invention belongs to the technical field of pesticide compounding, and particularly relates to theta-cypermethrin and methidathion containing suspoemulsion and an application thereof. The effective components of the suspoemulsion are theta-cypermethrin and methidathion, wherein the weight ratio of the methidathion to the theta-cypermethrin is 1:1-20:1. The theta-cypermethrin and methidathion containing suspoemulsion can be used for relieving the present pest resistance to insecticide to the greatest degree, thus the dosage of pesticide is reduced, and the influence on environments is also mitigated. The theta-cypermethrin and methidathion containing suspoemulsion is in line with the green and environmental protection trend of future society and has the optimal crop protection effect.

Description

technical field [0001] The invention belongs to the technical field of compounding pesticides and insecticides, and specifically relates to a suspoemulsion of high-efficiency trans-cypermethrin and methapon and its application. Background technique [0002] Methaphos [0003] One of the English names of methidathion is Methidathion, CAS number 950-37-8, molecular formula C 6 h 11 N 2 o 4 P.S. 3 , molecular weight 302.3313. [0004] The pure product is colorless crystal. The relative density is 1.495 (20°C), and the solubility at 20°C is: cyclohexanone 850g / kg, acetone 690g / kg, xylene 600g / kg, ethanol 260g / kg, water 250mg / kg. [0005] It has contact and stomach poisoning effects; it has osmotic effect but no systemic effect; it is a broad-spectrum, highly toxic insecticide and acaricide. [0006] However, its effect is also very single, and the risk of resistance after large-scale application is also very high. [0007] Beta-cypermethrin [0008] English name: theta...
