水稻病毒病田间小区药效试验一直是农药田间试验中最难有效完成的一类试验,该试验受传播介质、病毒、病毒病发生模型、抗病毒药剂效果等因素影响,田间药效试验重复性差和防治效果不理想。从供试水稻品种、试验地点、小区设置、清水对照处理和药效调查等方面对水稻病毒病田间试验方法进行探讨和总结,利于今后更好开展水稻病毒病田间药效试验。 The field efficacy test of rice virus disease has been one of the most difficult and effective tests in field trials of pesticides. The experiment is affected by factors such as the propagation medium, virus and virus disease model, antiviral effect and other factors. The repeatability of the field efficacy test is poor And the control effect is not ideal. The field trials of rice virus diseases were discussed and summarized from the aspects of test rice varieties, test sites, plot setting, clear water control treatment and efficacy investigation, which will benefit the field trials of rice virus disease in the future.
