Abstract: In order to explore the chemical weeding methods in millet fields and promote cost saving and income increase,the screening test of closed herbicides before seedling was carried out with Nenxuan 15 as test materials to investigate the control effects of different herbicides on narrow leaf weeds and their safety to crops.The results showed that each 100kg seeds was coated with 600mL EPEC seed coating agent,and closed weeding was carried out with 150mL·（666.7m~2）^-1 of dimethylpentalin+150mL·（666.7m~2）^-1 of atrazine.It had good control effect and economic benefits,and can be initially used for weed control under large-scale planting of millet.
