50%嘧菌环胺WG防治樱桃番茄灰霉病田间药效试验

Field Efficacy Trials of 50%Cyprodinil WG Controlling Cherry Tomato Gray Mold

采用6种杀菌剂对保护地樱桃番茄灰霉病进行药剂筛选试验。结果表明：50%嘧菌环胺水分散粒剂1 000倍液防效最好,为79.13%-84.84%;40%施佳乐悬浮剂1 000倍液次之,为75.72%-81.81%;20%嘧霉胺可湿性粉剂400倍液第三位,为73.24%-80.80%;40%施佳乐悬浮剂和20%嘧霉胺可湿性粉剂无极显著差异,但与其它3种药剂相比有极显著差异,值得在生产上推广应用。

Using six fungicides on Botrytis cinerea of cherry tomato in protected field to do pharmaceutical screening assays.The results showed that 50%cyprodinil WG 1 000 times had the best effect,79.13%~84.84%,40% of the Scala SC 1 000 times were the second,75.72%~81.81%,20% pyrimethanil WP 400 times were third,73.24%~80.80%,40% of the scala SC and 20%WP Promise pyrimethanil are not of much difference.Therefore,in the early stages,with 50% cyprodinil WG 1 000 times,40% of Scala SC 1 000 times,20% pyrimethanil WP 400 times of spraying for 2 times,gray mildew can be avoided.
