Ultra-low volume liquid containing novaluron and pyrethroid insecticides

Abstract

The invention relates to an ultra-low volume liquid containing novaluron and pyrethroid insecticides. The liquid is formed by compounding novaluron and an active ingredient II into an active ingredient, and the rest includes assistants and solvents which make up the weight percent to 100%; the active ingredient II is any one of cyfluthrin, fenvalerate, deltamethrin and ethofenprox. The ultra-low volume liquid disclosed by the invention has the advantages of convenience in processing, long duration, high work efficiency, low possibility of generating resistance to pesticides by a target, low environmental pollution, drug and water saving, and improvement on pesticide utilization rate; through ultra-low volume spraying, low volume spraying or ultra-low volume static spraying, various pests in rice, wheat, corn, vegetables, tobacco, tea trees, fruit trees and sugarcane can be prevented and treated.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to an ultra-low-capacity liquid formulation of fluorine-containing urea and pyrethroid pesticides. [0002] Background technique [0003] In recent years, pesticides have become a necessity in agricultural production and play an extremely important role in the defense of diseases and insect pests. With the continuous improvement of human living standards, food and environmental health issues are increasingly concerned by people. Therefore, all countries in the world The development of new pesticides and new dosage forms has been intensified. The ultra-low volume liquid is a new pesticide preparation with high efficiency, low toxicity and low residue. This dosage form can reduce the amount and frequency of use of pesticides and delay the emergence of insecticide resistance. , friendly to the environment, safe for non-targets such as humans and animals, can save water consumption for pestic...

AI Technical Summary

Problems solved by technology

[0016] Pyrethroid insecticides are a class of biomimetic insecticides successfully developed in the 1970s. Ester insecticides have developed resistance to most pests, and the control effect is not good

The control spectrum of fluorourea alone to control crop pests is narrow, and the quick effect is poor. If it is used alone for a long time, it is easy to produce resistance and reduce the control effect.

At the same time, if it is prepared into conventional dosage forms such as emulsifiable concentrates, wettable powders, and suspension concentrates, these conventional dosage forms can only be used for conventional spraying. If low-volume spraying is used, the droplets will be uneven, and the effect of regular spraying will not be achieved.

With the scale of crop planting, the use of the above-mentioned conventional agents for conventional spraying has low work efficiency, large dosage of agents, low control efficiency, and low utilization rate of agents
