Abstract

Experiments were conducted to monitor the dissipation of imazaquin and imazethapyr applied to the soil surface under conventional and no-tillage conditions. Imazaquin or imazethapyr dissipation rate was similar in no-tillage in 1985 and 1986. Dissipation of the herbicides under conventional tillage conditions varied. Imazaquin dissipation occurred 2.4 times faster in 1986 than in 1985. Imazethapyr dissipation was 3.5 times faster in 1986 than in 1985. Corn planted without tillage (no-till) was injured in 1986 where 210 or 280 g ha-1 of imazaquin or 105 g ha-1 of imazethapyr had been applied the previous year to conventionally tilled soybeans, but injury was not evident where these herbicides had been applied to no-tillage soybeans. Corn injury was evident 2 wk after planting in 1987 but yields were not reduced.
