Problems solved by technology

[0004] Many insecticides and acaricides have been developed for the control of various pests, and have been used alone or in combination with their agents in practice, but after repeated use, these agents have made some pests resistant to pesticides, and some are highly toxic. negative impact on the environment
However, it is very difficult to obtain an insecticidal and acaricidal combination that has no cross-resistance to existing insecticides and acaricides, has low toxicity, and has little negative impact on the environment.

Abstract

The pesticides which contains soluble powder of single-formamidine hydrochlorate belongs to the technic field of the composite pesticides, to resolve the drug resistance of the mite to the existing pesticides, the existing pesticides have a great poisonous character and have a side-effect to the environment. The pesticide which is made of abstracted single-formamidine hydrochlorate soluble powder compounded with pyrethroid species material, have a synergy effect and a stronger effect of destroying intectional worms.

Description

technical field [0001] The invention relates to a compound pesticide, more specifically, the invention relates to a compound pesticide containing monoformamidine hydrochloride soluble powder. Background technique [0002] N-(2,4-xylyl)-N'-methylformamidine hydrochloride, the Chinese name is monoformamidine hydrochloride, and the English name is Semiamitraz.chloride. It has been proved that monoformamidine hydrochloride can effectively It is an efficient and safe acaricide to effectively prevent and control mites, especially resistant mites, and can effectively prevent a variety of mites, such as cotton spider mite (Tetranychus urticae koch), orange rust mite (Aculops pelekassi), apple spider mite , Hawthorn Tetranychus and other mites. [0003] Pyrethroids are high-efficiency and broad-spectrum insecticides, which have strong contact stomach poisoning and anti-feeding effects, especially have high insecticidal activity against Lepidoptera pests, such as aphids, cotton bollw...
