Soil. Metabolites tentatively identified in soil were 5-bromo-3-(3-hydroxy-l-metliyl-propyl)-6-methyluracil, 5-bromo-3-sec-butyl-6-hydroxymethyluracil, 5-bromo-3-(2-hydroxy-l-methylpropyl)-6-methyluracil and carbon dioxide. The presence of uracil products suggests that bromacil was degraded via hydroxylation of the side chain alkyl groups. In the laboratory, 25.3% of C-bromacil degraded in soil to carbon dioxide after 9 weeks but mineralization in the field was not observed. The half-life of bromacil in a silt loam was 5-6 months (Gardiner et al., 1969).
