sufficient and uniform across all studies. The findings for 2,4-D (Enlist One) showed that adding an oil-based herbicide may increase waterhemp and giant ragweed control. However, there is an increased crop injury risk when adding both an oil-based herbicide and an oil-based adjuvant together in a tank mix. For Lactofen (Cobra), Cobra applied alone provided similar waterhemp control to those that included an oil-based adjuvant while also providing less injury. The findings for Glufosinate (Liberty ULTRA) in both waterhemp and giant ragweed control were very similar. Adding an oil-based herbicide, with or without a secondary oil-based adjuvant, appeared to improve Liberty ULTRA control for both waterhemp and giant ragweed. More research is to be conducted during the 2026 growing season.
