  • Interaction of ethofumesate with dry soil

    Creator:
    McAuliffe, David
    Abstract:
    Previous studies have shown loss of ethofumesate activity when the herbicide was applied to dry soil (2% w/w moisture content) in both field and greenhouse studies, even when rainfall or irrigation was received within a few days. Laboratory studies were conducted to determine the mechanism for this activity loss. Dry...

  • Effect of a pre-irrigation period on the activity of ethofumesate applied to dry soil

    Creator:
    McAuliffe, David
    Abstract:
    Applications of ethofumesate in Oregon have been observed from previous research and from commercial use to be less effective when applied to dry soils, even if subsequent precipitation occurred within a few days. Two field studies were established in the summer of 1979 using sweet corn (Zea mays L. 'Jubilee')...
