通过4%嘧肽霉素AS单独使用、与杀虫剂混用等处理,探讨对南方水稻黑条矮缩病的有效防治方法。试验结果表明,4%嘧肽霉素AS对南方水稻黑条矮缩病有一定的控制作用,可以通过化学调控措施降低感病植株体内的病毒浓度、减轻症状表现,增强健株的抗病能力,进而减轻病害所造成的损失,以病毒抑制剂+杀虫剂处理效果最为显著。
Through 4% pyrimidinomycin AS alone, mixed with insecticides and other treatments, to explore the southern rice black-streaked dwarf disease effective prevention and treatment methods. The results showed that 4% pyrimidinomycin AS had a certain control effect on rice black-streaked dwarf disease in southern China, and could reduce the virus concentration in susceptible plants through chemical control measures, alleviate the symptoms and enhance the resistance of healthy plants , And then reduce the damage caused by the disease, the most effective treatment with a virus inhibitor + insecticide.
