Abstract
Absorption and translocation of 14 C-fluroxypyr were determined for leafy spurge at various growth stages, under differing relative humidity and temperature conditions, and when applied with picloram or 2,4-D. Absorption of 14 C-fluroxypyr was greater in vegetative plants (39%) than in flowering or postflowering plants (25%), while total translocated to roots averaged 2% of applied herbicide regardless of growth stage. Greater 14 C-fluroxypyr absorption and translocation occurred in plants exposed to high relative humidity (>90%) compared to low humidity (<30%) for 6 h or longer following treatment. Absorption and translocation to roots was independent of temperature (18 or 24 C). Absorption and translocation declined by 50% when applied with picloram or 2,4-D. However, absorption and translocation of 14 C-picloram or 14 C-2,4-D were not affected by fluroxypyr. Fluroxypyr would likely be used in a leafy spurge control program only during environmental conditions adverse to control with picloram such as unseasonably warm or cold temperatures or in areas with a high water table.
