Abstract

Preemergence applications of DCPA (dimethyl 2,3,5,6-tetrachloroterephthalate) controlled germinating seedlings of largeseed dodder (Cuscuta indecora Choisy) in alfalfa, and the control continued throughout the season. Applications of DCPA were necessary prior to germination of dodder seed. Under California conditions, applications of DCPA made during early winter (December) provided early season control but not satisfactory control throughout the season as was accomplished with the March treatments. Autoradiographic studies showed only limited movement of tracer in alfalfa plants.
