Abstract

Foliar applications of 2-chloroethylphosphonic acid (CEPA) 7 days prior to spot applications of 14C-labelled 3,6-dichloro-o-anisic acid (dicamba) to leaves of wild garlic (Allium vineale L.) increased basipetal translocation of the dicamba as measured 7 days after dicamba treatment. High concentrations of CEPA were inhibitory. The ethylene released from CEPA degradation may have altered the metabolic “sink-source” relationships within the wild garlic plants allowing increased basipetal translocation of subsequent applications of dicamba when low concentrations of CEPA were applied.
