Abstract

Cyperus rotundus L.was a destructive weed in sugarcane field and caused serious damage to sugarcane production.Field plot experiment of four herbicides against Cyperus rotundus L.in sugarcane field was conducted.The result showed that XIANGSHAYIJIAN 56 %WP at the doses of 840 to 1680 a.i.g/hm2 had relatively good control effect on the 4-6 leaves of Cyperus rotundus L.and other broadleaves.After 45 days of application,its control efficiency against Cyperus rotundus L.was above 92.0 %,and it was safe to the sugarcane at the recommended rate of application.
