60%烯肟菌胺?丙森锌水分散粒剂对番茄早疫病的田间药效试验

Field Control Efficacy of 60% Enoximide?Propionzin WG on Tomato Early Blight

摘要: 为了明确60%烯肟菌胺•丙森锌水分散粒剂对番茄早疫病的防治效果，本研究使用8~48 g/15 L剂量的60%烯肟菌胺•丙森锌水分散粒剂进行田间药效试验。试验结果表明：施药后7天，60%烯肟菌胺•丙森锌水分散粒剂8~48 g/15 L对番茄早疫病的防治效果为18.78%~20.85%；施药后14天，防治效果为56.05%~66.03%。由此可见，60%烯肟菌胺•丙森锌水分散粒剂对番茄早疫病有较好的防治效果，且在试验剂量范围对番茄生长安全。

Abstract: Early blight of tomato is one of the major diseases threatening tomato production. In order to determine the control effect of 60% endoxime•propionzin WG on tomato early blight, the field efficacy of 60% endoxime•propionzin WG at the dosage of 8~48 g/15 L was carried out on tomato. The results showed that 7 days after application, the control effect of 60% endoxime•propionzin WG with dosage of 8~48 g/15 L was 18.78%~20.85%. And 14 days after application, the control effect was 56.05%~66.03%. Thus it can be seen, 60% endoxime•propionzin WG had a preferable control effect on tomato early blight, and was safe for tomato growth in the experimental dose range.
