2010—2011年进行30%氟菌唑可湿性粉剂防治梨黑星病和苹果白粉病田间药效试验。结果表明,30%氟菌唑可湿性粉剂3 000~5 000倍液对梨黑星病叶片的防效为81.44%~95.61%,对果实的防效为83.32%~96.11%;对苹果白粉病的防效为71.24%~85.13%。30%氟菌唑可湿性粉剂3 000~4 000倍液对梨黑星病的防效分别与生产上常用有效药剂400 g/L氟硅唑乳油8 000倍液、430g/L戊唑醇悬浮剂3 000倍液相当,无显著差异;30%氟菌唑可湿性粉剂3 000~4 000倍液对苹果白粉病的防效与生产上常用有效药剂50%硫磺悬浮剂300倍液相当,无显著差异。因此,在梨黑星病和苹果白粉病发病初期推荐使用30%氟菌唑可湿性粉剂3 000~4 000倍液喷雾,可控制病害流行。
2010-2011 Field efficacy test of 30% trifluconazole WP against pear scab and apple powdery mildew. The results showed that the control effect of 30% triflumizole WP 3 000 ~ 5 000 times against pear scab was 81.44% ~ 95.61% and the control effect was 83.32% ~ 96.11% The control effect was 71.24% ~ 85.13%. Control effect of 30% triflumizole WP 3 000 ~ 4 000 times on pears scab was respectively compatible with the effective dosages of 400 g / L fenfluosamon EC 8 000 times and 430 g / l tebuconazole Agent 3000 times, no significant difference; 30% of the flumeconazole wettable powder 3 000 ~ 4 000 times the control of apple powdery mildew and the production of commonly used effective agent 50% sulfur suspension 300 times equivalent, no Significant differences. Therefore, in the early onset of pear scab and apple powdery mildew, it is recommended to use 30% flumeconazole wettable powder 3 000 ~ 4 000 times the spray, can control the epidemic.
