  • The effect of soil factors on glyphosate availability in soil

    Creator:
    Kawate, Michael Ken
    Abstract:
    Glyphosate (N-(phosphonomethyl)glycine) is an effective foliar-applied herbicide with broad-spectrum activity. Greenhouse and laboratory experiments were conducted to determine the importance of soil moisture, autoclaved soil, soil type, sphagnum peat, soil pH, added phosphorus, and plant residues on crop establishment and growth when glyphosate was applied before emergence of the crop....

    Tanphiphat, Karin
    Abstract:
    Field studies were started at Hyslop Farm, Corvallis, Oregon in 1984 to determine the soil persistence of the herbicide clopyralid (3,6-dichloropicolinic acid) under cropping situations. The herbicide was sprayed on bare soil at the proposed use rate of 0.14 kg/ha in the spring and on the same plots at a...
