Twenty-two kinds of herbicides in low and high （twice） dosage were selected to conduct quantitative spray treatment on stem and leaf of pot Durante repens cv., then the inhibition rate of D. repens cv. and the efficiency of controlling dodder were investigated 30 d later. The results showed that the inhibition rate of D. repens cv. was lower than 20% while the efficiency of controlling dodder was higher than 80% by using 30, 60 mg/L 6% tusite AS, 364 mg/L 41% glyphosate isopropyl amine AS and 28 mg/L 10% hispyribac-sodium SC, of which the efficiency was high and the phytotoxicity could be accepted; on the other hand, the inhibition rate of D. repens cv. was 20.37%-100% while the efficiency of controlling dodder was 80.36%-100% by using 56 mg/L 10% bispyri
