摘要
本试验以马铃薯黑胫病常用防治药剂2%春雷霉素可湿性粉剂为对照,研究了6%春雷霉素可湿性粉剂对马铃薯的田间防病效果。结果表明,6%春雷霉素可湿性粉剂有效成分用量1.2-1.5g/100kg种薯的防效(70.36%、74.49%)显著地高于对照药剂2%春雷霉素可湿性粉剂(65.85%)。表明6%春雷霉素可湿性粉剂对马铃薯黑胫病具有较好的防治效果,对作物安全,可在生产中推广使用。
In this study,compared with 2%Kasugamycin WP,6%Kasugamycin WP is used to controll potato blackleg to research Field efficacy on it.The results showed that the control effects of 6%Kasugamycin WP with doses of 1.2 g/100 kg and 1.5 g/100 kg is better than it of 2%Kasugamycin WP.It showed that 6%Kasugamycin WP had good control effects on potato blackleg,it is safe for crops and could be popularized and used in potato production.
