Abstract

The loss of metribuzin and ethyl-metribuzin from soil and glass surfaces was studied to determine if volatilization and/or photodegradation could explain inconsistent weed control with these herbicides. In growth chamber experiments, phytotoxicity of ethyl-metribuzin decreased as the time between surface application and initial watering increased. Approximately 50% of the applied metribuzin and ethyl-metribuzin volatilized from soil within 24 h, with an additional 15 to 20% lost during the next 11 days, except about 5% additional ethyl-metribuzin was lost from Chehalis sandy loam. Both herbicides volatilized more rapidly from glass than from soil, with 75 to 90% of the loss occurring within 24 h and as great as 99% loss after 12 days. Loss by photodecomposition from soil or glass surfaces was minimal.
