REDUCED RATES OF POSTEMERGENCE HERBICIDES IN CONVENTIONAL SOYBEANS (GLYCINE-MAX)

The efficacy of reduced rates of fomesafen, bentazon plus acifluorfen, and chlorimuron, in combination with sethoxydim was investigated in New Jersey from 1989 to 1991. Herbicides applied at sequential 0.25x rates controlled common lambsquarters, common ragweed, and stinkgrass. Chlorimuron plus sethoxydim did not control common lambsquarters at any rate. Generally, herbicides applied at 0.5x rates were not as effective as the full or sequential 0.25x rates. Yields of plots treated with reduced rates were equal to or greater than those treated with full rates.
