Weeds in soybean fields is gradually formed the community main with Sonchus brachyotus D C .,Com‐melina communis L .and Cephalanoplos segetum .For more efficient controlling weeds ,some common herbi‐cides were tested .The results showed that 90% acetochlor effective ingredient dosages 1 782 g?hm‐2 + 25% fo‐mesafen effective ingredient dosages 375 g?hm‐2 sprayed before germination was the best ;postemergence with 12%clethodim effective ingredient dosages 252 g?hm‐2 + 48% bentazone effective ingredient dosages 1 080 g?hm‐2 was the best .If the “Three weeds” were more ,it could use 12% the clethodim effective ingredient dosages 252 g?hm‐2 or 10 .8% haloxyfop‐R‐methyl effective ingredient dosages 98 g?hm‐2 with 25% fomesafen effective ingredient dosages 375 g?hm‐2 spraying to achieve better control effect .
