Abstract

The invention discloses a compound medicament for rice seed soaking, which can effectively prevent and cure the nematode nematode and simultaneously treat bakanae disease. Its main components are thiazophos and metconazole, and the weight ratio of thiazophos and metconazole is 120:1-1:500. The invention can effectively overcome the shortcomings of narrow dosage form and easy degradation and instability of the traditional traditional control nematode cartap, and can effectively prevent and control rice bakanae disease resistant to carbendazim and prochloraz. Seed treatment agents for the control of rice seed-borne diseases can be developed into high-efficiency and environmentally friendly formulations such as emulsifiable concentrates, water-emulsions, and suspension concentrates. Moreover, the precise application of pesticides can be achieved by treating the seeds by soaking the seeds, which can significantly reduce the dosage of thiazophosphine per mu.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a rice seed soaking agent containing thiazophos and metconazole and an application thereof. Background technique [0002] Rice bakanae disease and dry sharp nematode are two common bell-borne diseases of rice in my country. Among them, rice bakanae disease is soaked with prochloraz all the year round, which leads to the obvious resistance of the pathogenic bacteria to prochloraz and the control effect decreases. Rice apical nematode disease occurs in all countries in the world. Although the leaf symptoms of the disease are mild, the number of grains per panicle decreases and the thousand-grain weight decreases due to the pricking and sucking damage to the ear primordium by the apical nematode during rice spikelet differentiation. Often cause serious damage to rice production. [0003] Cartap has been used for more than 30 years as a medicament for the control of ...
