In studying the absorption, distribution, and metabolism of dalapon (2,2-dichloropropionic acid) in relation to phytotoxicity, a number of simplified techniques were developed, and other established procedures were usefully modified. The techniques of autoradiography, extraction and fractionation, counting, and paper partition cochromatography were effectively combined, thus permitting qualitative and quantitative determination of distribution patterns and, to some extent, of the metabolic fate of translocated herbicides. Although this report is concerned specifically with dalapon, the approach employed with that compound should be applicable, with minor changes, to the study of others.
Physiological findings resulting from application of these techniques will be published separately.
