Abstract

The invention belongs to the technical field of pesticide compounding, and concretely relates to a chlorfenapyr-containing missible oil and its application. The effective components of the chlorfenapyr-containing missible oil comprise chlorfenapyr and methidathion, wherein a weight ratio of methidathion to chlorfenapyr is 20:1-1:1. The chlorfenapyr-containing missible oil has a good prevention and control effect especially on tea lesser leafhopper under the synergistic effect of the above components.

Description

technical field [0001] The invention belongs to the technical field of compounding pesticides and insecticides, and specifically relates to an emulsifiable concentrate containing chlorfenapyr and its application. Background technique [0002] Methaphos [0003] One of the English names 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] chlorfenapyr [0008] The English name Chlorfenapyr is a new type of heterocy...
