Abstract

Tolerances of soybean and rotational crops wheat and corn to chlorimuron (0.02 to 0.14 kg ai ha–1), clomazone (0.56 to 3.36 kg ha–1), imazaquin (0.07 to 0.42 kg ha–1) and imazethapyr (0.05 to 0.31 kg ha–1) were evaluated in field studies. No visible soybean injury was observed. No reduction in soybean population, height, or yield occurred from the use of these herbicides, in 1986 or 1987. Differences in wheat yields among treatments were not significant in 1987 or 1988. Corn population, number of ears, ear weight, or yield were not different.
