摘要： Although faba-bean ( Vicia faba L.) is not a major crop in China, many farmers like to cultivate faba-bean in autumn as a fresh food or animal feed for next spring. However, no herbicides are available to control weeds in the faba-bean fields. Although prosulfocarb is a candidate herbicide, some farmers have reported that prosulfocarb can often cause harm to faba-bean. Our laboratory experiment results revealed that Tongcanxian No. 6, a faba-bean cultivar with large seeds, showed the lowest level of growth inhibition and Qidou No. 2, a faba-bean cultivar with small seeds, showed the highest level of growth inhibition when treated with 3960 and 7920 g ai ha(-1) prosulfocarb. The growth inhibition rate of faba-bean was 0% when 3960 and 7920 g ai ha(-1) prosulfocarb was sprayed within 6 d after sowing, indicating that prosulfocarb treatment should be applied as soon as possible after sowing. When the temperature exceeded 20 degrees C and soil moisture content exceeded 20%, it might have aggravated the phytotoxicity of 'Tongcanxian No. 6' and 'Qidou No. 2' caused by prosulfocarb. Two round of field experiments showed visually that the control effect of 3960 g ai ha(-1) prosulfocarb on the total weeds exceeded 90% and safe to faba-bean at the same time. This study indicated that prosulfocarb can be safely used in faba-bean fields by improving agronomic methods, which can also provide a reference for weed management in faba-bean fields worldwide.
