为了探索南方水稻黑条矮缩病的防治方案,采用30%毒氟磷可湿性粉剂等6种药剂进行了田间药效试验,并结合播前拌种及稻飞虱防治等措施摸索了一套针对南方水稻黑条矮缩病的防控技术体系。结果表明:播种前用“优拌”拌种(5 mL/kg),移栽前10天用25%吡蚜酮可湿性粉剂1 800倍液喷施一次,在3叶一心及田间出现感病植株时用30%毒氟磷可湿性粉剂1000倍液或3%超敏蛋白微粒剂1000倍液分别防治,能有效控制该病的危害,保证水稻高产稳产,可在江华县水稻生产中推广使用。
In order to explore the prevention and treatment plan of rice black-streaked dwarf disease in southern China, the field efficacy test was carried out with six kinds of agents, such as 30% toxic fluorine phosphorus wettable powder, and combined with measures such as seed dressing before sowing and planthopper control Aiming at the prevention and control system of rice black-streaked dwarf disease in southern China. The results showed that seed dressing (5 mL / kg) was used before sowing and sprayed with 1 800 times of 25% pymetrozine wettable powder 10 days before transplanting, When the infected plants are treated with 1000 times of 30% toxic fluticasone WP or 1000 times of 3% hypersensitive protein microgranules, respectively, they can effectively control the harm of the disease and ensure the high and stable yield of rice. In the rice production of Jianghua County Promote use.
