Abstract
The experiment for controlling weed with 52% WP of nicosulfuron and atrazine was conducted in summer maize field in 2009.The results showed that the optimum dosage of 52% WP of nicosulfuron and atrazine was 75~100 g per 666.7m2;the control effect for weed plant number was 89.3%～95.2% after treated for 20 days;the control effect for weed fresh weight was 90.6%～96.3% on the 40th day;the maize yield increased by 9.43%~16.23%,so it was safe to summer maize.
