Abstract
Studies were conducted under greenhouse and field conditions to determine phytotoxic interactions on soybean, Glycine max (L.) Merr. genotypes differing in their sensitivity to metribuzin when metribuzin was applied sequentially with phorate. Consistent phytotoxic interactions between metribuzin and the soybean cultivars occurred during the study, with relatively greater phytotoxicity occurring when Woodworth-Rps1b, a line sensitive to metribuzin, was used. Also, consistent phytotoxic interactions occurred when the two pesticides were applied sequentially. Relatively more phytotoxicity occurred with higher rates of each (metribuzin: 0.56 kg [AI]/ha and phorate; 1.6 kg [AI]/ha). In addition, a three-way interaction among phorate, metribuzin, and soybean genotype occurred throughout the study. The synergistic interaction between phorate and metribuzin caused more severe phytotoxicity on the moderately metribuzin-sensitive line, ‘Woodworth’, and the greatest phytotoxicity on the highly sensitive line, Woodworth-Rps1b. The least phorate/metribuzin phytotoxic interaction was on ‘Union’, which is metribuzin tolerant.
