Abstract

A safened herbicidal composition for use in corn (maize) including a herbicidally effective amount of (a) a compound of formula (I):

or an agriculturally acceptable salt or ester thereof and (b) a safener or a compatible herbicide capable of safening such as AD67, benzenesulfonamide, benoxacor, N-(aminocarbonyl)-2-chlorobenzenesulfonamide (2-CBSU), daimuron, dichlormid, dichloroacetamide, dicyclonon, fenchlorazole-ethyl, fenclorim, fluxofenim, furilazole, isoxadifen-ethyl, mefenpyr-diethyl, naphthopyranone, naphthalic anhydride (NA), oxabetrinil, oxime, phenylpyrimidine, phenylurea, a chemical from the quinolinyloxyacetate family of chemicals, or agriculturally acceptable salts, esters, or mixtures thereof. Methods for using the safened herbicidal composition for controlling undesirable vegetation in corn (maize) also are described.
