Abstract

Fourteen field experiments were conducted from 1988 to 1991 in Oklahoma to evaluate herbicides for red horned poppy control in winter wheat. Chlorsulfuron applied alone PRE at 9 to 26 g ai ha-1 or with metsulfuron controlled red horned poppy 90 to 100% in four of five locations. MCPA at 420 g ae ha-1 and MCPA + bromoxynil at 140 + 140 g ae ha-1 applied POST in mid November controlled red horned poppy 100%. All herbicides applied POST in mid March failed to control the weed consistently.
