摘　　要：利用0.75、1.50、2.25 kg/hm2三种浓度的44%谷友(单嘧·扑灭)WP对高粱田杂草的防除效果及高粱生长发育的影响进行了田间药效试验。结果表明,喷施浓度为2.25 kg/hm2时防除杂草效果最好,药后30 d对阔叶杂草的鲜重防效和株防效分别为96.09%和63.18%;对阔叶杂草防效明显优于禾本科杂草,对杂草鲜重防效明显优于株防效;44%谷友(单嘧.扑灭)WP对高粱全生育期生长无明显影响,各农艺性状和产量性状与对照差异不显著。The control and its effects on sorghum efficacy growth 2. 25 kg/hm^2. The results showed of 44% monosulfuron plus propazine were studied at the concentrations that the weed control effect was WP on the weeds in sorghum fields of 0. 75 kg/hm^2, 1.50 kg/hm：, the best at the concentration of 2. 25 kg/hm2, and the fresh - weight and stem control efficacy on broadleaf weeds were 96. 09% and 63.18% respectively after 30 days. The control efficacy on broadleaf weeds was obviously better than that on gramine- ous weeds, and the control efficacy for fresh weight was significantly better than that for plants. 44% monosul- furon plus propazine WP had no obvious injury to sorghum in the whole growth periods, and the agronomic traits and yield components of sorghum didn＇ t change significantly compared to those of the check.
