International Classification:

A01N 2532

US Classification:

504110

Abstract:

A composition containing an effective amount of a herbicide and an aqueous ammoniacal ionic solution of metal alkanoates is disclosed. Alkanoates having from 2 to 6 carbon atoms are preferred, with acetates most preferred. Metals selected from the group consisting of boron, calcium, copper, iron, magnesium, manganese, molybdenum, potassium, sodium and zinc are preferred, with zinc particularly preferred. Both broadleaf and grass herbicides are preferred, with herbicides having an active ingredient selected from the group consisting of quizalofop, sodium salt of bentazon, sodium salt of acifluorfen, chlorimuron ethyl, lactofen, fluazifop-p-butyl, fenoxaprop-ethyl, methyl 3-[[[[4-methoxy-6-methyl-1,3,5-triazin-2-yl]amino]carbonyl]amino]sulfonyl] 2-thiophenecarboxylate, 2-[1-ethoxyimon]butyl]-5-[2-[ethylthio]propyl]-3-hydroxy-2-cyclohexene-1-o ne, and ammonium salt of imazethapyre.
