Field plot experiments were conducted to evaluate the efficacy and selectivity of acetochlor , oxyfluorfen , and pendimethalin in sweet potato ,.All treatments were selective to sweet potato .Acetochlor 50%EC (4 500 mL/hm2 ) bet-ter controlled Gramineae weeds 30 d and 45 d after spraying whereas oxyfluorfen 24%EC (1 500 mL/hm2 ) was more ef-fective on broadleaf weeds .Acetochlor 50%EC ( 4 500 mL/hm2 ) and oxyfluorfen 24%EC at 750 mL/hm2 and 1 500 mL/hm2 at 30 days after application provided 73%,66%,and 84% weed control,which increased to 87%,84%,and 89% at 45 days,respectively.Based on fresh weight the respective control levels were 93%,97%,and 98%.Both herbi-cides effectively controlled weeds in sweet potato fields .
