    Peanut Control in Rotational Crops

    Authors: , ,


Volunteer peanut (Arachis hypogaea L.) can reduce the effectiveness of crop rotation as a component in a peanut disease management program. Experiments were conducted in three states to evaluate peanut control with glyphosate [N-(phosphonomethyl)glycine] or with herbicides commonly applied postemergence for broadleaf weed control in corn (Zea mays L.) and cotton (Gossypium hirsutum L.). Two sequential applications were needed for acceptable control with corn and cotton herbicides. Greater than 80% control of peanut was achieved with dicamba (3,6-dichloro-2-methoxybenzoic acid) applied early postemergence (EPOST) followed by dicamba or ametryn [N-ethyl-N'-(l-methylethyl)-6-(methylthio)-1,3,5-triazine-2,4-diamine] applied late postemergence (LPOST). MSMA (monosodium salt of methylarsonic acid) applied EPOST followed by oxyfluorfen [2-chloro-1-(3-ethoxy-4-nitrophenoxy)-4-(trifluoromethyl)benzene] + MSMA LPOST and fluometuron [N,N-dimethyl-N-3-trifluoromethyl) phenyl]urea] + MSMA applied EPOST followed by prometryn [N,N'-bis(1-methylethyl)-6-(methylthio)-1,3,5-triazine-2,4-diamine] + MSMA, cyanazine [2-[[4-chloro-6-(ethylamino)-1,3,5-triazin-2-yl]amino-2-methylpropanenitrile] + MSMA, lactofen {(±)-2-ethoxy-1-methyl-2-oxoethyl 5-[2-chloro-4-(trifluoromethyl)phenoxy]- 2-nitrobenzoate} + MSMA, or oxyfluorfen + MSMA LPOST controlled peanut at least 80%. Single applications of glyphosate at 0.84 to 1.12 kg ae/ha controlled peanut at least 80% and were at least as efficacious as the same total rate of glyphosate applied sequentially.
