| 摘 要： | 采用孢子萌发法测定了烯肟菌胺与丙森锌按照不同配比(质量比1∶1、1∶3、1∶5、1∶7及1∶9)复配对番茄早疫病菌的联合毒力,并验证了60%烯肟菌胺·丙森锌(质量比1∶9)水分散粒剂(WG)对番茄早疫病的的田间防治效果。结果表明:烯肟菌胺与丙森锌单剂对茄链格孢菌的EC50值分别为1.5140mg·L-1和11.9888mg·L~(-1),烯肟菌胺与丙森锌按1∶1、1∶3、1∶5、1∶7及1∶9混配时均表现出明显的增效效应。田间试验结果表明,在番茄早疫病发病初期间隔7d连续喷施2次60%烯肟菌胺·丙森锌WG对番茄早疫病具有较好防效,推荐剂量为480~960g·hm~(-2)。

| Abstract: | Synergic toxicity of mixture containing fenaminstrobin and propineb at different mass ratios（1∶1，1∶3，1∶5，1∶7，1∶9）on tomato early blight was tested by spore germination method，and field application effect of the mixed fenaminstrobin and propineb 60% WG（mass ratios 1∶9）on tomato early blight was also evaluated. The results showed that the EC50 of fenaminstrobin and propineb to Alternaria solani were 1.514 0 mg·L-1 and 11.988 8 mg·L-1，respectively. The 5 matching mass ratios（1∶1，1∶3，1∶5，1∶7，1∶9）all showed obvious synergistic effects. The results of field experiment indicated that tomato early blight could be controlled by the mixed fenaminstrobin and propineb 60% WG twice every other week during the initial stage of leaf spot occurance，and the recommended dosage was 480-960 g·hm-2. |
