| 摘 要： | 目的]水稻秆腐菌核病是苏打盐碱地水稻重要病害,为了筛选防治水稻秆腐菌核病有效杀菌剂对17种杀菌剂进行试验。方法]利用生长速率法,对供试药剂建立毒力回归线,进行EC值分析。计算病情指数和防效并进行差异显著性分析。结果]50%异菌脲WP、25%咪鲜胺(德国)EC和25%咪鲜胺EW防治效果明显,达到了80%以上;25%丙环唑EC达到70%。结论]防治苏打盐碱地水稻秆腐菌核病首选50%异菌脲WP、25%咪鲜胺(德国)EC和25%咪鲜胺EW,25%丙环唑EC可以作为备选药剂。

| Abstract: | Sclerotiniose blight of rice stem rot is an important plant disease in the sodium bicarbonate soil of the Songnen plain.Effective fungicides to the disease were screened in this study.Methods] Probit regression lines were established by using plate mycelium growth rate method,and EC values were analyzed.Then,disease indexes and control effects were calculated,and difference significances were analyzed by DPS software.Results] Control effects of iprodione,prochloraz(made in Germany) and prochloraz(made in China) exceeded 80%,and that of propiconazole was 70%.Conclusions] First,fungicide iprodione,prochloraz(made in Germany) and prochloraz(made in China) were used to control sclerotiniose blight of rice stem rot in the sodium bicarbonate soil.Then,fungicide propiconazole could be a candidate. |
