新杀菌剂烯肟菌酯对马铃薯晚疫病的防治效果

Control Efficacy of Enestroburin against Potato Late Blight

室内及田间试验结果表明,烯肟菌酯对马铃薯晚疫病具有较优异的防治效果。室内盆栽活性EC90值为34.01mg/L,田间使用剂量在50～200ga.i./hm2范围内对马铃薯晚疫病的防效为80%～90%。25%烯肟菌酯EC用于防治马铃薯晚疫病的有效剂量为100～200ga.i./hm2,一般施药2～3次,间隔7～8d。

Greenhouse tests and field trials were conducted to evaluate the control efficacy of enestroburin against potato late blight. The EC90 was 34.01 mg/L. It gets 80-90% control activity against potato late blight in field at the rate of 50-200 g a.i./ha. Enestroburin 25% EC showed good control efficacy when applied 2 to 3 times with 8 days interval at rate 100-200 g a.i./ha.
