Problems solved by technology

[0011] Fenoxycarb is a non-terpene carbamate compound, which has stomach toxicity and contact action, and has the effect of insect growth regulator, and has a broad spectrum of insecticide; but its insecticidal effect is non-neurotic, which is manifested as A variety of insects have strong juvenile hormone activity, which can kill eggs, inhibit the metamorphosis of adults and molting of larvae, and cause the death of larvae after pupa or pupal stage. It has a long lasting effect and is harmless to beneficial organisms.
[0012] However, the abuse has made the pests generally develop strong resistance to this kind of pesticides, and the control effect is not as good as before.

Abstract

The invention belongs to the technical field of pesticide compounding and particularly relates to fenoxycarb-containing missible oil and application. The fenoxycarb-containing missible oil consists of fenoxycarb and methidathion as effective constituents, wherein the weight ratio of methidathion to fenoxycarb is 20:1 to 1:1; and the fenoxycarb-containing missible oil is particularly good for controlling gelechiid moths, which mainly results from a synergistic interaction effect of various constituents.

Description

technical field [0001] The invention belongs to the technical field of compounding pesticides and insecticides, and specifically relates to an emulsifiable concentrate containing fenoxycarb 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] Fenoxycarb [0008] 【Chemical name】[2-(4-phenoxyphenoxy)ethyl] ethyl carbamate....
