【摘要】 为探明醚菌酯、啶酰菌胺可湿性粉剂以及苯醚甲环唑水分散粒剂对胡麻白粉病的防治效果以及对胡麻的安全性,进行了田间防效试验。结果表明,50%啶酰菌胺可湿性粉剂对胡麻白粉病防效最好。在胡麻白粉病始发前或始发初期,用50%啶酰菌胺可湿性粉剂540 g/hm~2,兑水675 kg,第一次用药后,根据病情发展,一周后再喷第二次药剂,两地三年防效在26.16%～74.79%,种子产量比对照增加5.93%～26.78%。经农产品检验检测中心对50%啶酰菌胺可湿性粉剂处理的种子进行农药残留检测,未检测出啶酰菌胺残留,因此该药剂可大面积推广使用。更多还原

【Abstract】 In order to investigate the control effect of kresoxim-methyl, boscalid wettable powder and difenoconazole water dispersible granule on linseed powdery mildew and its safety, field control effect tests were carried out. The results showed that 50% boscalid wettable powder had the best control effect on linseed powdery mildew. Before or at the beginning of the outbreak of linseed powdery mildew, 50% boscalid wettable powder was used to prepare 540 g/hm~2 and 675 kg of water. After the first dose, spray the second dose one week after the disease progresses. The three-year control effect at two locations is 26.16%-74.79%, and the yield is increased by 5.93%-26.78% compared with the control. The fungicide residue of seeds treated with 50% boscalid wettable powder was detected by the agricultural product inspection and testing center, and no bosclid residue was found in the seeds, so the pesticide can be widely used.更多还原
