应用甲磺隆与阔叶净2种除草剂按不同比例混配,以2,4-D丁酯和清水分别为对照,进行2年防除草地狼毒Stellera chamaejasme的试验研究,结果表明,甲磺隆:阔叶净=1:1(用药量0.159 6 g/m2)防除草地狼毒效果最好,防效达97.5%,但对禾本科和阔叶草的影响较大;甲磺隆:阔叶净=2:1(用药量0.05985 g/m2)对禾本科和阔叶草的影响最小,没有负作用,同时它对狼毒的防除效果也比较好,防效可达90%,能有效抑制草地狼毒群落,在生产防治上应选用甲磺隆:阔叶净=2:1(用药量0.059 85 g/m2)进行推广防除草地狼毒.
Effect of mixed herbicide on controlling Stellera chamaejasme
Methsulfuron-methyl and tribenuron-methyl were mixed in different proportion to control Stellera chamaejasme with 2,4-D and clean water as control group. The results from two year's experiment showed that the ratio of 1 : 1 of methsulfuron-methyl and tribenuron-methyl (0.159 6 g/m2) controlled 97. 5% chamaejasme which was the best effect but the effect on grass and broad-leaf grass was more significant. While the ratio of 2 : 1 (0. 059 85 g/m2) controlled 90% chamaejasme and had no negative effect on grass and broad-leaf grass. By the experiment, the ratio of 2 : 1 of methsulfuron-methyl and tribenuron-methyl is recommended to be used in production.
