Ultralow-volume liquid containing novaluron and carbamate insecticides

Abstract

The invention discloses an ultralow-volume liquid containing novaluron and carbamate insecticides. The ultralow-volume liquid comprises chemical components formed by compounding novaluron and an active component II, as well as the balance being a surfactant and a solvent, wherein the active component II is any one of carbosulfan, fenobucarb, isoprocarb, triazamate, meta-tolyl-N-meth ylcarbamate, methomyl and thiodicarb. According to the formula, the ultralow-volume liquid comprises the following components in percentage by weight: 0.1-20 percent of novaluron, 0.1-30 percent of the active component II, 1-10 percent of an additive, and the balance being the solvent. The ultralow-volume liquid disclosed by the invention is convenient to process, long in lasting period and high in work efficiency; a target is unlikely to generate resistance to insecticide; environmental pollution is low; the insecticide and water are saved; the utilization rate of the insecticide is increased; by adopting ultralow-volume spraying, low-volume spraying or ultralow-volume electrostatic spraying, various insects of rice, wheat, corn, vegetables, tobaccos, tea trees, fruit trees and sugarcane are prevented and treated.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to an ultra-low-capacity liquid formulation of fluorine-containing urea and carbamate 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 f...

AI Technical Summary

Problems solved by technology

[0015] At present, due to the long-term frequent single use of carbamate insecticides to control rice planthoppers and other pests, serious resistance problems have been caused. The amount per mu is large, and the control effect is low, which has a great impact on the environment.

The single use of fluorourea to control crop pests has a narrow control spectrum and poor quick effect. 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
