Abstract

GAF 141 [(2-chloroethyl)phosphonic acid plus N-methylpyrrolidone] increased basipetal translocation of glyphosate [N-(phosphonomethyl)glycine], dicamba (3,6-dichloro-o-anisic acid), and acifluorfen {5-[2-chloro-4-(trifluoromethyl)phenoxyl]-2-nitrobenzoic acid} in bean seedlings (Phaseolus vulgaris L. 'Stringless Greenpod′). The GAF 141 was applied as a foliar treatment before or at the same time as herbicide injection into the cotyledonary node. GAF 141 applied 24 h prior to glyphosate, dicamba, or acifluorfen injection enhanced basipetal translocation to the roots and inhibited acropetal translocation to the young shoots. GAF 141 applied simultaneously with the herbicide injection did not have substantial effects on translocation. Greater basipetal translocation of acifluorfen occurred at high (75 ± 5%) than at low relative humidity (35 ± 5%).
