Improving the efficacy of clethodim herbicide against annual ryegrass

To investigate the factors influencing (i.e. ryegrass size) performance of ‘dim’ herbicides Select (a.i. clethodim) & Factor (a.i. butroxydim) on Group A resistant ryegrass in canola.本研究旨在探究影响‘dim’类除草剂（商品名Select，有效成分（active ingredient，简称a.i.）为烯草酮（clethodim）；商品名Factor，有效成分（a.i.）为丁环草酮（butroxydim））在双低油菜田中对A组抗性黑麦草（Group A resistant ryegrass）防效的因素，具体为黑麦草的个体大小。
