Field studies were conducted in 1994 and 1995 to evaluate the effect of imazethapyr on peanut growth and yield under weed-free conditions as influenced by timing of application. Imazethapyr applied preemergence (PRE) and 7, 21, 35, 49, and 63 d after planting (DAP) had no effect on peanut pod weight. In 1 of 2 yr, imazethapyr applied PRE, 21 DAP, or 35 DAP increased yield over the untreated check. In 1 of 2 yr, peanut grade was reduced with imazethapyr applied 49 DAP.
