Abstract

Herbicidal injury caused by 6-(trisubstituted phenyl)-4-amino-2-pyridinecarboxylates in wheat and barley is reduced with the use of AD67 (MON 4660), benoxacor, 2-CBSU, daimuron, dichlormid, dicyclonon (BAS 145 138H), fenchlorazole-ethyl, fenclorim, fluxofenim, furilazole (MON 13900), glyphosate, isoxadifen-ethyl, mefenpyr-diethyl, naphthalic anhydride, oxabetrinil and mixtures thereof.
