对8种杂草进行了田间试验，以确定氯嘧磺隆、氟磺胺草醚、咪唑乙烟酸或甲磺草胺在两种剂量下（标记剂量和标记剂量的一半）是否与草甘膦在210和420 g ai ha−1下的互补罐混剂。使用放射性标记的草甘膦、氯嘧磺隆和咪草烟对稗草、牵牛花、Palmer阿马兰斯和绒叶进行了实验室实验，以确定这些除草剂单独和组合应用的吸收和转运模式。在田间，草甘膦和氯嘧磺隆的罐混物通常是添加剂。添加氯嘧磺隆并没有减少稗草，去核牵牛花，或天鹅绒叶吸收或转运的14 C-草甘膦。添加草甘膦增加了苋菜和绒叶苋对14 C-氯嘧磺隆的吸收。所有四个氟磺胺草醚加草甘膦率组合是拮抗的牛鞭草，镰状，Palmer阿马兰斯，和天鹅绒，和四个拮抗稗草和全叶牵牛花。氟磺胺草醚降低了稗草、牵牛花和绒叶草对14 C-草甘膦的吸收和转运。90%的草甘膦加咪唑乙烟酸组合是加和或协同的，所有比率组合对去核牵牛花都是协同的。在咪草烟中添加草甘膦可增加Palmer阿马兰斯和绒叶对14 C-咪草烟的吸收。草甘膦加甲磺草胺罐混合物是拮抗在所有速率组合稗草和帕尔默阿马兰斯并在三个四个组合的鹅耳草和全叶牵牛花，表明这些除草剂是不互补的罐混合物。
Field experiments were conducted on eight weed species to determine if chlorimuron, fomesafen, imazethapyr, or sulfentrazone at two rates (labeled and one-half the labeled rate) were complementary tank mixtures with glyphosate at 210 and 420 g ai ha−1. Laboratory experiments were conducted on barnyardgrass, pitted morningglory, Palmer amaranth, and velvetleaf using radiolabeled glyphosate, chlorimuron, and imazethapyr to determine the absorption and translocation pattern of these herbicides applied alone and in combination. In the field, glyphosate plus chlorimuron tank mixtures were generally additive. Adding chlorimuron did not decrease absorption or translocation of 14C-glyphosate by barnyardgrass, pitted morningglory, or velvetleaf. Adding glyphosate increased absorption of 14C-chlorimuron by Palmer amaranth and velvetleaf. All four fomesafen plus glyphosate rate combinations were antagonistic to goosegrass, sicklepod, Palmer amaranth, and velvetleaf, and three of the four were antagonistic to barnyardgrass and entireleaf morningglory. Fomesafen decreased absorption and translocation of 14C-glyphosate in barnyardgrass, pitted morningglory, and velvetleaf. Ninety percent of glyphosate plus imazethapyr combinations were additive or synergistic, with all rate combinations synergistic for pitted morningglory. Adding glyphosate to imazethapyr increased absorption of 14C-imazethapyr by Palmer amaranth and velvetleaf. Glyphosate plus sulfentrazone tank mixtures were antagonistic at all rate combinations for barnyardgrass and Palmer amaranth and at three of the four combinations for goosegrass and entireleaf morningglory, indicating that these herbicides are not complementary in tank mixtures.
