Flumioxazin for Weed Control in Texas Peanuts (Arachis hypogaea L.)¹

Authors: W. James Grichar , A. Edwin Colburn

Abstract

Field experiments were conducted in 1991 and 1993 to evaluate flumioxazin alone and in various herbicide programs for weed control in peanut. Flumioxazin alone provided inconsistent control of annual grasses, while the addition of pendimethalin or trifluralin improved control considerably. Pitted morningglory (Ipomoea lacunosa L.) and ivyleaf morningglory Ipomoea hederacea (L.) Jacq. control was > 75% when flumioxazin was used alone. Flumioxazin caused early season peanut stunting with some recovery within 4 to 6 wk. Postemergence applications of imazethapyr or lactofen increased peanut stunting.
