Dinotefuran and copper calcium sulphate suspension emulsion and application thereof

Abstract

The invention provides a dinotefuran and copper calcium sulphate suspension emulsion and application thereof, relating to a suspension emulsion containing active ingredients including dinotefuran and copper calcium sulphate, wherein the weight ratio of dinotefuran to copper calcium sulphate ranges from 1:50 to 50:1. The invention also relates to application of combination of dinotefuran and copper calcium sulphate to prevention or control of citrus canker, bacterial blight of rice and bacterial soft rot of vegetables. Dinotefuran and copper calcium sulphate are compounded to achieve synergism, the fungicidal effect of the composition is remarkably improved compared with that of a single dosage agent, the suspension emulsion is safe to human and livestock, the probability of drug resistance of pests is low, the dosage and the cost of the pesticide are reduced and the environment damage is alleviated.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a suspoemulsion of dinotefuran and copper calcium sulfate and its application. Background technique [0002] Dinotefuran is a neonicotinoid insecticide developed by Mitsui Corporation of Japan. Its chemical structure is very different from that of the existing neonicotinoid insecticides. Its tetrahydrofuryl group replaces the previous chloropyridyl and chlorothiazolyl groups, and does not contain halogen elements. The base is different, so people call it "furan nicotine" at present. The agent has a wide insecticidal spectrum, has a systemic osmotic effect, and exhibits high insecticidal activity at a very low dose. The agent is very safe to mammals, birds and scholarly organisms, and has no harm to crops, and can be used for rice, fruit trees, vegetables and many other crops. [0003] Copper calcium sulfate (copper calcium sulphate) is a broad-spectrum protective fungicide with a neu...

AI Technical Summary

Problems solved by technology

[0004] Due to the long-term use of the above two agents alone, it is easy to lead to the generation of drug resistance of bacteria, resulting in a significant decline in drug efficacy, resulting in a large increase in dosage, shortened spraying cycle, and poor use effect, which increases costs. The use of a large number of pesticides makes the bacteria The resistance is more serious, and it also has a certain impact on the environment. The drug residues in agricultural products also increase, which affects the health and normal survival of humans and animals. The compound use of dinotefuran and copper calcium sulfate is used to prevent and control crop diseases. Domestic Not yet reported
