Abstract

Absorption and translocation of 14C following 14C-fluazifop {(±)-2-[4-[[5-(trifluoromethyl)-2-pyridinyl] oxy] phenoxy] propanoic acid} butyl ester and 14C-sethoxydim {2-[1-(ethoxyimino)butyl]-5-[2-(ethylthio)propyl]-3-hydroxy-2-cyclohexen-1-one} application to oats (Avena sativa L. ‘Lyon’) was greater when the herbicides were applied with oleic acid, linoleic acid, or fatty acid methyl esters compared to various triglycerides. The methyl esters of stearic, oleic, linoleic, and linolenic acids enhanced 14C absorption and translocation when applied with 14C-fluazifop and 14C-sethoxydim, except that the methyl ester of stearic acid did not enhance 14C absorption and translocation when applied with 14C-sethoxydim. The absorption and translocation of 14C following the application of 14C-CGA-82725 {(±)-2-[4-(3,5-dichloro-2-pyridyloxy)phenoxy] propanoic acid)-2-propynylester}, 14C-diclofop {(±)-2-[4-(2,4-dichlorophenoxy)phenoxy] propanoic acid}, 14C-fluazifop, and 14C-sethoxydim were generally enhanced equally or greater by the methyl ester of sunflower (Helianthus annum L.) oil than by petroleum oil additive or once refined sunflower oil. Methylated sunflower oil was equally or more effective as an additive than petroleum oil in enhancing grass control with fluazifop and sethoxydim in a field experiment.
