Abstract

Addition of ammonium nitrate greatly increased the absorption of solutions of the isooctyl ester of (2,4,5-trichlorophenoxy)acetic acid (2,4,5-T) by sweetgum (Liquidambar styraciflua L.), post oak (Quercus stellata Wangenh.), red maple (Acer rubrum L.), and loblolly pine (Pinus taeda L.) leaves. Phosphoric acid alone and mixed with ammonium nitrate caused less increase. Ammonium nitrate speeded translocation of the herbicide in post oak but not in the other species.
