but no DCBP, were detected in cottonseed (EI Zorgani, 1975) and in extracts
of cotton leaves that presumably included surface residues and tissue metabolites
(Nash et al., 1977). Kelthane was metabolized to at least three unknown polar
products in a microsomal preparation from suspended parsley cells (Sandermann
et al., 1977).
