| 摘 要： | 通过室内孢子萌发试验和盆栽试验测定了苦皮藤杀菌剂对黄瓜霜霉病菌的活性。结果表明,4%苦皮藤可湿性粉剂和4%苦皮藤乳油对黄瓜霜霉病菌的孢子囊萌发均有强烈的抑制作用,在40mg/L时,抑制率均达100%;盆栽试验结果表明,无论在子叶期还是真叶期,4%苦皮藤可湿性粉剂对黄瓜霜霉病都有良好的保护作用和显著的治疗作用,其防效均优于甲霜灵。

| Abstract: | The result of the bioassay against Pseudoperonospora cubensis showed that 4% celangilin wettable powder and 4% celangilin emusifiable concentrates would have strong effect on inhibiting the germination of the sporangium.At 40 mg/L concentration,their inhibiting rates can both reach 100%.The pot experiment showed that whether in host's cotyledon or euphylla period,4% celangilin wettable powder has good protective efficacy and remarkable therapeutic efficacy,and it's control efficacies are better than metalaxyl during the two host's growing periods. |
