Abstract

C14-ring-labeled 2-chloro-4-diethylamino-6-isopropylamino-s-triazine (ipazine) was soil-applied to young cotton plants or placed in solution cultures. C14-labeled constituents accumulated in the lysigenous glands of roots, stems, and leaves. Retranslocation of C14-labeled components into new growth after removal of C14-ipazine from solution cultures did not occur. No evolution of of C14O2 by C14-ipazine-treated plants was detected, but evolution of C14O2 occurred from C14-ipazine-treated soil. Some unaltered C14-ipazine was present in leaves and stems sampled 3 months after treatment. No C14-ipazine could be detected in seed formed on treated plants. Free hydroxyipazine did not constitute a major degradation product. However, hydroxyipazine and other basic substances appeared to be released upon hydrolysis of a chloroform-soluble, non-distillable component that accumulated in roots and leaves. An ethanol-insoluble, non-dialyzable component also accumulated in leaves and roots.
