摘要
在温室条件下研究了磺草酮的除草活性及安全性,磺草酮茎叶处理对多数玉米品种的选择性指数大于4,说明其对玉米的安全性比较好。高剂量下处理,对玉米的药害症状表现为叶片局部白化现象,不同类型玉米的敏感程度基本相同。沈单16和新铁单10号比较敏感。
Sulcotrione activity and safety has been studied in Greenhouse. The selectivity exponent of sulcotrione was more than four. It means that sulcotrione was safety to corn. Under sulcotrione high rate, some maize species showed a little injure symptom. The symptom was that corn leaf was partly bleached. The sensitivity of most corns are similar. In all the experiment corn species Shendan16 and Xintiedan10 showed more sensitive to sulcorrione.
