摘　　要：[目的]就目前市面现有的种衣悬浮剂对红麻发芽率的影响及苗期立枯病的防控效果进行评价。[方法]通过室内和田间2种方法进行评价。[结果]29%噻虫·咯·霜灵FS 1.16 mg/kg处理的种子发芽势最高,提高出苗率方面表现最好;12%甲·嘧·甲霜灵FS 1.32 mg/kg的对红麻立枯病菌的防控效果最好,防效达94.29%,其次为25%咯菌腈FS 0.15 mg/kg,防效达93.46%。[结论]上述3种悬浮种衣剂值得在生产上推广应用。[Aims] This study aims to evaluate the effect of the flowable concentrate for seed coatingon kenaf germination rate and the prevention and control effect against seedling blight disease. [Methods] The green house test and field trials were used to evaluate kenaf germination rate and prevention and control effect on kenaf seedling blight.[Results] The results showed that the seed germination potential was the highest treated with of thiazolam 29% FS at1.16 mg/kg, which was the best performance in the improvement of seedling rate. The thiophanate-methyl ·azoxystrobin·metalaxyl 12% FS at 1.32 mg/kg has the best inhibitory effect on R. solani of kenaf and the control effect amount to 94.29%, also the fludioxonil 25% FS at 0.15 mg/kg comes to second with 93.46% control effect.[Conclusions] The above three kinds of flowable concentrate for seed coating are worthy to be popularized and applied in production.
