对21 2%草除灵·喹禾灵·胺苯磺隆WP防除油菜田杂草的药效进行了研究。结果表明,21 2%草除灵·喹禾灵·胺苯磺隆WP对油菜田主要杂草防效优良,对油菜安全。每公顷用该产品190 8g(ai),药后30d、药后60d对油菜田主要杂草的株防效均在90%以上,且药后60d的鲜重防效也在90%以上。
The efficacy of 21 2% sedazolone and quizalofop-p-ethyl-tribenuron-methyl WP in controlling weeds in rapeseed field was studied. The results showed that 21 2% of the herbaceous quizalofop-tribendronate trimethoprim WP had good control effect on the main weeds in the rape fields and was safe to rapeseed. The control efficacy of 190 8g (ai), 30 days after treatment and 60 days after treatment on the major weeds in rapeseed field was over 90% per hectare, and the fresh weight control effect was over 90% after 60 days.
