Action and Fate of 2,4-D and Dicamba in Trumpetcreeper
Published online by Cambridge University Press: 12 June 2017
Abstract
Trumpetcreeper [Campsis radicans (L.) Seem.] grown from 10-cm root sections was more susceptible to foliar applications of 2,4-D [(2,4-dichlorophenoxy)acetic acid] and dicamba (3,6-dichloro-o-anisic acid) than trumpetcreeper grown from 45-cm root sections. Dicamba controlled trumpetcreeper better than did 2,4-D, particularly trumpetcreeper grown from 45-cm root sections. More 14C-dicamba than 14C-2,4-D was absorbed through the foliage and translocated to the roots of trumpetcreeper grown from 10-cm roots. No 14C-2,4-D was detected in the 45-cm roots; however, 14C-dicamba was recovered from both the upper and the lower sections of the 45-cm roots.
