Uptake, Translocation, and Degradation of Diphenamid in Plants

  • S. W. Bingham (a1) and Richard Shaver (a1)


The rate of uptake and translocation of N,N-dimethyl-2,2-diphenylacetamide (diphenamid-14C) varied among different species. Apoplastic translocation of diphenamid occurred rapidly in tomato (Lycopersicon esculentum Mill.) seedlings, intermediate in bermudagrass (Cynodon dactylon L. ‘328’) and slowly in winged euonymus [Euonymus alatus (Thunb.) Seib. ‘compacta’]. Diphenamid-14C was dealkylated to give N-methyl-2,2-diphenylacetamide (MDA) in both winged euonymus and tomato plants. After 8 days, approximately 60% of the benzene-extractable labeled compounds from both plants was MDA and 39% was diphenamid. However, less of the radioactive material in winged euonymus was extracted.
