Abstract

The invention relates to application of a sterilization compound containing 2-amino-5-mercapto-1,3,4-thiadiazole zinc and thiodiazole copper in reduction or prevention of rice infection by toxins formed by xanthomonas oryzae pathovar oryzicola. The sterilization compound containing the 2-amino-5-mercapto-1,3,4-thiadiazole zinc and the thiodiazole copper is applied according to a ratio with which acombination has a synergistic effect on reduction or prevention of rice infection by the toxins formed by xanthomonas oryzae pathovar oryzicola. Rice seeds and seedlings, rice plants, rice leaf sheaths and soil where rice is about to be planted are treated by the sterilization compound containing the 2-amino-5-mercapto-1,3,4-thiadiazole zinc and the thiodiazole copper by means of seed treatment,foliar application, stem application, thorough soaking, dripping, pouring, spraying, atomizing, dusting, spreading, fuming or the like.

Description

Technical field [0001] The present invention relates to the use of a bactericidal composition containing zinc thiazole and copper thiazolin to reduce or prevent rice from being infected by Xanthomonas oryzae pathovar oryzicola. Background technique [0002] Rice bacterial streak is one of the main diseases that harms rice, and its pathogenic bacteria is Xanthomonas oryzae pathovar oryzicola. Xanthomonas oryzae is a variant of Xanthomonas oryzae. Research on the pathogenic mechanism of rice bacterial leaf spot at home and abroad is still in its infancy. In order to reduce or prevent rice from being infected by B. oryzae, the currently used measures are mainly: [0003] (I) Strengthen seed quarantine work and prevent long-distance spread of pathogenic seeds during production and transportation; [0004] (II) If conditions permit, crop rotation between flood and drought can be carried out in three years; [0005] (III) Select disease-resistant varieties; [0006] (IV) Pest...
