Abstract
In an effort to confirm the results of a study in 1971 to determine the length of time required for parathion to degrade to 'zero' levels, parathion was applied twice at a rate of .375 lb/acre to field tobacco in South Carolina. After each application, parathion degraded to 'zero' levels in 5 days. These results tended to confirm the findings of the original study in which the maximum time required for parathion to degrade to zero levels was estimated to be 7 days and the minimum time 2 days. Weather was characterized by scanty rainfall and temperatures averaging 76 degrees F. During the original study rainfall was heavy and daily temperatures averaged 80.9 degrees F.
