Evaluation of Preemergence and Postemergence Herbicides for Sweet Corn Weed Control

Abstract

Callisto at 0.24 lb AI/A applied PREE gave a similar level of control of prostrate pigweed as did Dual Magnum, Outlook, and Prowl. POST applications of Callisto at 0.188 lb AI/A were equivalent to the higher rate of 0.24 lb AI/A. Callisto, Distinct, and Clarity provided excellent POST control of pigweed. Callisto applied POST was the same as PREE followed by POST sequentially. Aim provided marginally acceptable control of pigweed.
