Abstract/Contents:"Field research was conducted in 1984 to evaluate potential antagonistic effects from tank-mix or sequential applications of bentazon (0.8 kg/ha) and/or acifluorfen (0.4 kg/ha), 3 and 5 days following sethoxydim (0.3 kg/ha) compared to applications of sethoxydim (0. kg/ha) 3, 5, and 7 days following bentazon (0.8 kg/ha) and/or acifluorfen (0.4 kg/ha) for control of 8- to 12-cm barnyardgrass (Echinochloa crus-galli). Sethoxydim (0.2 kg/ha) at the recommended labeled rate was applied as a comparison. Sethoxydim applied alone did not result in adequate grass control (79%). When sethoxydim was applied 3 days following bentazon, grass control was greater than 90% which indicates that the increased rate of sethoxydim in the sequential treatment was enough to increase grass control and overcome any antagonism. When the sequential sethoxydim treatment was applied 5 or 7 days after acifluorfen and/or bentazon, grass control was not significantly increased over sethoxydim alone, indicating that antagonism occurred with a 5 or 7 day intervall in the sequential treatment. Bentazon or acifluorfen plus bentazon applied 3 or 5 days following sethoxydim resulted in greater than 90% grass control. These results indicate that antagonism between sethoxydim and bentazon or acifluorfen can be overcome, and that with sequential applications the best results are obtained if sethoxydim is applied first."
