AI Technical Summary

Problems solved by technology

As a result, nematodes' resistance to thiazophosphine increased rapidly, and the control effect was greatly reduced
In order to effectively control nematodes, it is necessary to double the dosage of thiazophosphine, which will bring about three problems: first, the resistance of pests will become stronger; second, increase the agricultural input of farmers; third, Aggravate environmental pollution and damage to non-target organisms; if no effective solution is found, thiazophosphine will soon be eliminated due to resistance problems
At present, there is no relevant report about the compounding of thiazophosphine and the compound of formula 1

Abstract

The invention relates to a nematicidal composition containing fosthiazate and a compound shown in the formula 1. The active ingredients of the nematicidal composition comprise fosthiazate and the compound shown in the formula 1 according to a weight ratio of 1:20 to 20: 1, wherein preferably, the weight ratio is 1: 10 to 10: 1. The two active ingredients of the composition can produce synergisticeffects so that the prevention and control effect is improved, the used amount of pesticide is reduced, the growth of crops is promoted and the nematicidal composition is worthy of promotion and application.

Description

technical field [0001] The invention belongs to the technical field of pesticide nematodes, and in particular relates to a nematicidal composition containing thiazole phosphine and styryl-containing 1,3,4-oxadiazole sulfide compounds as active ingredients, which is used for preventing and controlling nematodes . Background technique [0002] Nematodes are a common agricultural disease with a wide range of hosts, including hundreds of crops such as melons, solanaceous fruits, beans, radishes, and cabbage. The global annual loss caused by nematodes to agriculture is about 100 billion yuan. With the development of my country's agricultural production and rural economy, the multiple cropping index caused by the excessive pursuit of high-value economic crops continues to increase, and the limited cultivated land area makes it difficult to rotate crops and stubble, resulting in more serious nematode damage. [0003] Thiazophosphine is an organophosphorus nematicide, the main mod...
