Abstract:	The effect of 50% quinclorac WP on controlling high leaf-age barnyard grass in rice seedling was eminent,the cure rate was high and it was safe for rice growth.By spraying stems and leaves with 0.75 kg/hm2 50% quinclorac WP in seedling stage,the controlling rate against 3~5 high leaf-age barnyard grass was up to 98%,and the rice seeding wasn′t hurt.

Keywords:	50% quinclorac WP rice seedling high leaf-age barnyard grass control effect safety
