水稻病毒病田间小区药效试验方法的探讨

The Discussion of Method about the Field Efficacy of Rice Virus Disease

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 trials of rice virus disease has been the most difficult to conduct in all kinds of field trials about pesticides because of it involving with many factors contained with plant hoppers,rice virus,rice variety,model about viral disease,the effect of anti-viral agent. So this field efficacy trial appears to be poor test repeatability and control effect also is not satisfactory. In the paper,the field test methods contained the tested rice varieties; the experiment site,the field plot,water control treatment and efficacy investigation are discussed and summarized in order to carry out the field of efficacy rice virus diseases in the future.
