百草枯（420克/公顷）对7至25厘米高的稗草的控制率为48至74%，草甘膦（1120克/公顷）为83至87%，草铵膦（840克/公顷）为85至91%。在大多数情况下，稗草控制没有加强与添加残留除草剂嗪草酮加氯嘧磺隆，嗪草酮，或灭草喹。不超过13 cm高的稗草和幼苗约翰逊草无论除草剂处理均被控制至少90%。当根茎和幼苗约翰逊草存在时，草甘膦的控制率为96%，而百草枯为55%，草铵膦为86%。非选择性除草剂和残留除草剂的桶混剂一般能增强对全叶牵牛花和去核牵牛花、大麻田菁（15至30厘米）和多刺黄花菜（15至18厘米）的控制。在大多数情况下，大豆产量没有增加与添加残留除草剂。单独施用草铵膦后的产量比施用百草枯后的产量高25%，所有除草剂处理的产量比不施用非选择性除草剂时的产量至少高45%。
Barnyardgrass 7 to 25 cm tall was controlled 48 to 74% with paraquat (420 g/ha), 83 to 87% with glyphosate (1120 g/ha), and 85 to 91% with glufosinate (840 g/ha). In most cases barnyardgrass control was not enhanced with addition of residual herbicides metribuzin plus chlorimuron, metribuzin, or imazaquin. Barnyardgrass and seedling johnsongrass no more than 13 cm tall was controlled at least 90% regardless of herbicide treatment. When rhizome and seedling johnsongrass were present, control with glyphosate was 96% compared with 55% for paraquat and 86% with glufosinate. Tank-mixtures of non-selective and residual herbicides generally enhanced control of entireleaf and pitted morningglory, hemp sesbania (15 to 30 cm), and prickly sida (15 to 18 cm). Soybean yields in most cases were not increased with addition of residual herbicides. Yield following glufosinate applied alone was 25% higher than following paraquat, and for all herbicide treatments yields were at least 45% greater than when a non-selective herbicide was not applied.
