稗草和牵牛花对照POST，草铵膦840 g a.i./当春耕与除草剂施用间隔不超过35 d时，处理后28 d的ha分别为79 - 85%和83 - 90%。在相同剂量下，草铵膦对黄花稔和大麻田菁的防效分别为68%和92%。用560和840 g/ha的草铵膦获得可比的稗草控制，其大于420 g/ha。大麻田菁控制是相似的所有率草铵膦。相比之下，百草枯1，050克活性成分/ HA防治稗草40 - 65%、牵牛花44 - 75%、黄花稔41%和田菁92%。840 g a.i./公顷草甘膦和SC-0224、稗草、牵牛花、黄花稔和田菁的防效分别为55 - 89%、55 - 81%、45 - 61%和56 - 68%。1050克/公顷百草枯和840克/公顷草铵膦、草甘膦和SC-0224处理的大豆产量分别是未处理对照的5.8、7.6、6.0和5.9倍。
Barnyardgrass and morningglory control POST with glufosinate at 840 g a.i./ha 28 d after treatment was 79 to 85% and 83 to 90%, respectively, when no more than 35 d elapsed between initial spring soil tillage and herbicide application. For the same rate of glufosinate, prickly sida and hemp sesbania were controlled 68 and 92%, respectively. Comparable barnyardgrass control was obtained with glufosinate at 560 and 840 g/ha, which was greater than at 420 g/ha. Hemp sesbania control was similar for all rates of glufosinate. In comparison, paraquat at 1050 g a.i./ha controlled 40 to 65% barnyardgrass, 44 to 75% morningglory, 41% prickly sida, and 92% hemp sesbania. With 840 g a.i./ha glyphosate and SC-0224, barnyardgrass, morningglory, prickly sida, and hemp sesbania were controlled 55 to 89%, 55 to 81%, 45 to 61%, and 56 to 68%, respectively. Soybean yield was 5.8, 7.6, 6.0, and 5.9 times greater than the nontreated check for 1050 g/ha paraquat and 840 g/ha glufosinate, glyphosate, and SC-0224, respectively.
