摘　　要：丙酯草醚、烯草酮等与其他除草剂复配后对油菜田禾本科杂草具有很好的防除效果,其对野燕麦的防效为96.2%~97.8%,显著高于单剂83%左右的防效;对看麦娘和早熟禾,使用复配剂和单剂均有很好的防除效果,防效分别约为97%和94%。对阔叶类杂草繁缕和婆婆纳,复配剂和单剂都有良好的防除效果,防效为89.7%~93.1%;对猪殃殃和通泉草防除效果一般,防效为70%左右。The combination of pyribambenz-propyl and the others such as clethodim have an ex- cellent control effect on gramineous weeds in rapeseed field. The control effect of the combination on wild Arena fatua L. is between 96. 2%-97. 8%, while that of the single agent is about 83%, which shows that there is a good synergism of clethodim on controlling Arena fatua L. The difference between the control effect of the compound and that of the single agent on Alopecurus aequalis Sobol. and Poa annua L. is not significant, accordingly being around 97% and 94%. For broad leaf weed, the control effects of propyl ether, isopropyl ether and their combination on Stellaria media （L.） Cyr. and Veronica didyma Tenore are both good, accordingly being around 89.7% and 93.1%. The combination has only a general control effect on Galiurn aparine L. vat. tenerum Gren. et （Godr.） and Mazus japonicas （Thunb.）, which are both about 70%.
