2 POST broadleaf Bentazon + acifluorfen (1994 NR & WR, 1995 NR, 1996 NR); fomesafen (1994 NR & WR, 1995 NR & WR); 2,4-DB + linuron (1996 NR & WR).
About three weeks later after the cover crops were established and able to be competitive with dryland soybean, acifluorfen {5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoic acid} plus 2,4-DB [4-(2,4-dichlorophenoxy)butanoic acid] was applied post-directed between soybean rows to suppress cover crop and any escaped weed growth.
In 1991 about two weeks after application of acifluorfen plus 2,4-DB, cover crop plants were counted in three random quadrats each 0.
Acifluorfen plus 2,4-DB plus X-77 surfactant caused 86% injury to black medic when applied in SP main plots vs 55% injury in V1 main plots.
Application of acifluorfen plus 2,4-DB plus surfactant through center-row drop nozzles likely suppressed legume cover crop competition with soybean, but this was not a treatment variable.
