Abstract

The invention discloses a paddy rice seed soaking compound agent which can effectively prevent aphelenchoides besseyi and also can treat bakanae disease. Main ingredients of the paddy rice seed soaking agent are fosthiazate and metconazole, and the weight ratio of fosthiazate and metconazole is (120 to 1) to (1 to 500). The paddy rice seed soaking agent can effectively overcome the weaknesses that the traditional agent for preventing the aphelenchoides besseyi is limited in form, easy to degrade and unstable and can effectively prevent the paddy rice bakanae disease having fastness to carbendazim and prochloraz. The paddy rice diseased seed processing agent can be developed into high-efficiency environment-friendly forms such as missible oil, emulsion in water, suspension and the like. Seeds are processed in a soaking manner, so that precision in agent application can be realized, and the dosage of the fosthiazate per Mu can be obviously reduced.

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 ...
