Abstract

The invention discloses a pesticide composition for rice seed treatment and application thereof. The pesticide composition for treating rice seeds includes active ingredients, the active ingredients include tebuconazole, thiram and cartap, wherein the mass ratio of the tebuconazole, thiram and cartap is 1 ~20:1~20:1~20. The invention also discloses the application of the pesticide composition in the prevention and treatment of rice bakanae disease or / and rice apical nematode disease. The pesticide composition of the invention can effectively control the resistance of Fusarium Fujikura to fungicides such as carbendazim and prochloraz, and at the same time reduce the risk of potential resistance of Fusarium Fujikura to tebuconazole and thiram respectively. The combination of tebuconazole, thiram and cartap has a remarkable effect on the control of rice bakanae disease and rice stem nematode disease.

Description

technical field [0001] The invention relates to the prevention and treatment of rice seed-transmitted diseases, in particular to a pesticide composition for treating rice seeds and its application. Background technique [0002] Rice bakanae disease, mainly caused by Fusarium fujikuroi (Gibberella fujikuroi), has occurred in almost every rice-growing area in the world since it was first reported in Japan in 1828. The disease not only causes a yield loss of up to 50%, but also poses food safety problems due to the production of fumonisins and other toxic metabolites by the pathogen. For a long time, the control of rice bakanae disease has mainly relied on chemical agents for seed treatment. At present, there are more than 140 kinds of preparations (including single agents and compound agents) registered for the control of rice bakanae disease in China, and about 85% of the preparations have prochloraz, carbendazim or fludioxonil as active ingredients, and most of the preparat...
