“爱苗”防治草莓白粉病的试验

Experiment on Controlling Strawberry Powdery Mildew Disease with Aimiao

[目的]为了筛选防治草莓白粉病的高效药剂,确定30%爱苗（15%苯醚甲环唑＋15%丙环唑）乳油的防效。[方法]通过田间对比试验,比较了30%爱苗乳油和20%福星（氟硅唑）乳油不同浓度、不同施药时间后的对草莓白粉病的防治效果。[结果]爱苗3 000倍于第3次施药后14 d对草莓白粉病的防效为95.95%,防效理想。爱苗5 000倍同样方法施用,第3次施药后14 d对白粉病的防效为85.87%。福星3 000倍液与爱苗3 000倍液的防效相当。[结论]爱苗1 500倍液试验对草莓生长安全有示范推广价值,建议使用剂量3 000-5 000倍液。

[Objective] The study aimed to screen the high - efficient pesticides to control strawberry powdery mildew and ascertain the control effect of 30% Aimiao emulsifiable solution （15% difenoconazole ＋ 15% propiconazole）. [Method] The comparison of control effects of 30% Aimiao emulsifiable solution and 20% Fuxing emulsifiable solution （flusilazole） with different concentrations and application time on strawberry powdery mildew were done in field comparison test. [Result] The control effect of Aimiao diluted 3 000 times on strawberry powdery mildew in 14 days after the third application was ideal, being 95,95%. The control effect of Aimiao diluted 5 000 times on strawberry powdery mildew in 14 days after the third application was 85.87%. The control effects of Fuxing diluted 3 000 times and Aimiao diluted 3 000 times was equivalent. [Conclusion] Experiment with Aimiao diluted 1500 times had demonstration and popularizing values to the growth safety of strawberry and the Aimiao dosage was suggested to be diluted 3 000- 5 000 times.
