Summary:[ Objective] The paper was compare the control effects of different doses of MCPA-Na on weeds in foxtail millet field. [ Method ] Different doses of MC- PA-Na were sprayed on foxtail millet field, while artificial weeding and spraying water was designed as control. The strain control effect and fresh weight control effect were calculated. [Result]The strain control effect and fresh weight control effect of 2 250 g/hm^2 MCPA-Na at 25 and 40 d post spraying were the best, and the fresh weight control effects reached 84.19% and 87.23%, respectively. Compared to CK, the yield increase effect of 1 500 g/hm^2 was the best, and the yield increase rate was 54.31% ; followed by 1 125 g/hm^2. Generally, 1 500 g/hm^2 was the best dosage of MCPA-Na in foxtail millet production. [ Conclusion]The paper provided a theoretical basis for screening the best dose of herbicide in foxtail millet production.
