敌力脱(丙环唑)和井冈霉素两种药剂采用生长速率法 ,室内毒力测定对小麦纹枯病菌的EC50 分别为0.33mg/L和0.27mg/L ;EC99 为30.07mg/L和640.82mg/L;田间施药10d防效分别为86.72%和76.58 % ,且在95 %水平上差异性显著。表明25%敌力脱乳油防治小麦纹枯病优于井冈毒素
The growth rate method was used for the determination of virucide (propiconazole) and validamycin (EC50), and the EC50 was 0.33 mg / L and 0.27 mg / L respectively for indoor toxicity test of R. solani. EC99 was 30.07 mg / L And 640.82mg / L, respectively. The control effects of field application for 10 days were 86.72% and 76.58%, respectively, and the difference was significant at 95% level. This indicates that 25% of the enemy’s de-emulsifying oil is superior to Jinggang’s toxins in controlling wheat sheath blight
