Abstract

Pitted morningglory and entireleaf morningglory treated with 14C-imazaquin translocated 14C to areas above and below the treated leaf. Pitted morningglory absorbed and translocated more 14C from 14C-imazaquin than entireleaf morningglory. Translocation of 14C from root-supplied 14C-imazaquin was similar in both species 1 d after treatment, with 14C moving rapidly to the shoots. Entireleaf morningglory metabolized slightly more imazaquin than pitted morningglory in treated leaves. Greater tolerance of entireleaf morningglory than pitted morningglory to postemergence applications of imazaquin is attributed to reduced absorption and translocation and increased metabolism of the herbicide in the entireleaf morningglory.
