Problems solved by technology

[0004] However, if a single dose of thiazophosphine is used on a large scale for a long time, it will easily lead to the emergence of pest resistance, and farmers will often increase the dosage during use, which will increase the burden on the environment and cause a vicious circle, which is not conducive to sustainable development. develop

Abstract

The invention discloses a nematicidal composition containing fosthiazate. The composition comprises an effective component A, namely, fosthiazate, and an effective component B, wherein the effective component B is one selected from amino-oligosaccharin, azadirachtin and ivermectin; the weight ratio of the effective component A to the effective component B is (1: 10)-(50: 1); the optimal weight ratio of the effective component A to the effective component B is (1: 5)-(10: 1); the effective components take up 0.2%-40% of the total weight of the composition. According to the invention, the composition can be prepared into various dosage forms applicable to agricultural production, such as a suspending agent, a water emulsion, granules, water dispersible granules and wettable powder, particularly slow-release granules; the nematicidal composition is mainly used for preventing and treating the root knot nematode diseases of vegetable crops, food crops, lawn grass, fruit trees, and the like.

Description

technical field [0001] The invention belongs to the field of agricultural fungicides, in particular to a nematicide composition containing thiazophosphine and its application. Background technique [0002] Thiazophosphine is an organophosphorus nematicide with contact and systemic effects. The main mode of action is to inhibit the synthesis of acetylcholinesterase in root-knot nematodes. It can be used to control various types of root-knot nematodes. Thiazophosphine has the advantages of fast insecticidal speed, long-lasting effect, low toxicity, and less residue, and is widely used in agricultural production. [0003] Amino oligosaccharin (oligochitosaccharide) is a low-toxic fungicide obtained by degrading chitin first to chitosan and then degrading it, or extracting it by microbial fermentation. The compound not only has a strong control and eradication effect on fungi, bacteria and viruses, but also has the effects of nutrition, regulation, detoxification and antibacter...
