Field experiments of nicosulfuron·atrazine 80% WG were carried out for control of weeds in spring maize field at the 2~5 leaf stage of maize.The results showed that it had a good control effect of gramineous weeds and broadleaf weeds. The control effects of gramineous weeds and broadleaf weeds plant number were 70.63% ~92.13% after treated for 20 days;the control effect for weed fresh weight were 71.55%~94.67% on the 40th day,the maize yield increased by 13.04%~16.74%. No negative effects on mazie growth were found.
