Abstract
Abstract Field experiments compared single and sequential applications of lactofen {+-2-ethoxy-1-methyl-2-oxoethyl 5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoate} to the standard herbicide programs of alachlor [2-chloro-N-2,6-diethylphenyl)-N-(methoxymethyl)-acetamide] + paraquat (1,11-dimethyl-4,41-bipyridinium ion) and acifluorfen {5-[2-chloro-4-(trifluromethyl)phenoxy]-2-nitrobenzoic acid} + bentazon {3-(1-methyl-ethyl)-1H-2,1,3-benzothiadiazon-4(3H) 2,2-dioxide} for broadleaf weed control. A single late postemergence (LPOST) application of lactofen controlled morningglory species (Ipomoea spp.) and prickly sida (Sida spinosa L.) as well as lactofen applied early POST (EPOST) and LPOST. Lactofen applied sequentially at groundcracking (GC) and EPOST provided greater and/or more consistent control of common lambsquarters (Chenopodium album L.) and prickly sida than alachlor+paraquat applied GC or acifluorfen+bentazon applied LPOST. Ipomoea spp. control was less with a single LPOST application of lactofen than with acifluorfen+bentazon applied LPOST in 1988. Eclipta (Eclipta prostrata L.) was controlled with single or sequential lactofen applications and with acifluorfen+bentazon applied LPOST. Peanut yield was greater when lactofen was applied at GC followed by an EPOST application compared with a single application of lactofen applied LPOST, acifluorfen+ bentazon applied LPOST, or alachlor+paraquat applied GC.
