Abstract

The invention relates to an application of a zinc thiazole and kasugamycin composition in disinfection of potato seeds, and a method thereof, and the zinc thiazole and kasugamycin composition is used for treating the potato seeds so as to prevent and treat potato diseases caused by phytopathogen fungi or bacteria. According to the method, zinc thiazole and kasugamycin composition is used for treating potato seeds, preventing and treating potato diseases caused by phytopathogen fungi or bacteria, promoting growth of potatoes in the seedling stage and improving the yield and quality of potatoes, wherein the weight ratio of zinc thiazole to kasugamycin in the composition is 10: 1-5: 1. The zinc thiazole and kasugamycin composition in a specific proportion range is adopted to treat the potato seeds, seedling growth of potatoes can be effectively promoted on the premise of effectively preventing and treating potato diseases, the quality and yield of potatoes are improved, the potato seeds are treated differently in different potato sowing periods, different planting habits of vast potato planting areas can be met, and large-area application and popularization value is achieved.

Description

technical field [0001] The invention relates to the use and method of disinfecting seed potatoes with the composition containing thiazole zinc and kasugamycin. Background technique [0002] Potato is the "fourth largest food crop" in the world. The potato planting area in my country accounts for 20%-25% of the total potato area in the world. The hazards of soil-borne diseases are difficult to control once they occur. Potato blackleg is currently one of the major diseases affecting potato growing areas. [0003] Potato black shank is a bacterial disease caused by Erwinia carotovora subsp. atroseptica, which can be transmitted through bacteria-carrying rainwater, insects, irrigation water, steam mist, machinery, weeds and soil. The pathogen Erwinia carotovora subsp.atroseptica causing potato black shank is different from the pathogen Erwinia carotovora subsp.carotovora causing Chinese cabbage soft rot. The former mainly hosts potatoes, while the latter has a wide range of hos...
