To explore the effect of herbicide prevention,the effect of 96%(S)-Metolachlor EC on the weed control in potato field and its effect on the growth safety and yield of potato were studied.The results showed that45 days after the applying pesticid,96%(S)-Metolachlor EC had better control effect by(S)-Metolachlor dosage of 750,975 and 1 200 mL·hm-2,and the average fresh weight control effect of Echinochloa crusgalli,Setaira viridis,Commelina communis and Abutilon theophrasti was 76.06%,83.13% and 85.28%.Potato yield increased significantly in three concentrations of 96%(S)-Metolachlor EC,the yield increasing rate was 2.80%,4.50%,7.10%.It was safety and no phytotoxicity for potato by 96%(S)-Metolachlor EC was used before emergence after seeding.96%(S)-Metolachlor EC was no adverse effects on potato growth,had better weed control effect,played a certain role in the promotion of the potato yield increase,in terms of economic efficiency and safety which can be used as the main herbicide potato field.
