Comparative studies of herbicides and herbicide mixtures were conducted at Tifton, Georgia, in 1959 and 1960. Certain mixtures, which contained sodium 2,4–dichlorophenoxyethyl sulfate (sesone), tris(2,4–dichlorophenoxyethyl) phosphite (2,4–DEP), or the triethylamine salt of 3–amino–2,5–dichlorobenzoic acid (amiben) mixed with the alkanolamine salt of 4,6–dinitro–o–sec-butylphenol (DNBP), gave seasonal weed control on band-treated peanuts. Compared to herbicides applied singly, mixtures not only increased the spectrum of weeds controlled but also permitted the use of the lowest rate of each component on the weeds for which it was most effective.
