Abstract

Soil samples were taken from 32 commercial cotton fields of the mid-south which had been treated with one or more practical applications of 3-(3,4-dichlorophenyl)-1,1-dimethylurea (diuron)2 every year for the past 4 to 8 years. These samples showed no phytotoxic residues in laboratory and greenhouse studies conducted approximately one year after the last application. Cotton seed samples from eight of these fields were analyzed, and none contained a detectable residue of diuron or any of its breakdown products. Diuron degradation in soil under field conditions was demonstrated by isolation and identification of the intermediate breakdown products: 3-(3,4-dichlorophenyl)-1-methylurea, 1-(3,4-dichlorophenyl)urea, and 3,4-dichloroaniline.
