A Carrier for Some Water-Soluble Herbicides
Published online by Cambridge University Press: 12 June 2017
Abstract
A mixture of dimethyl sulfoxide (DMSO), glycerol, phytobland oil, and water (50:25:15:10, v/v) proved to be outstandingly effective as a carrier for water-soluble formulations of 4-amino-3,5,6-trichloropicolinic acid (picloram), (2,4,5-trichlorophenoxy)acetic acid (2,4,5-T), and mixtures thereof. The carrier was selected after numerous experiments in which these and other adjuvants, used individually, gave at least some degree of herbicidal enhancement on velvet mesquite seedlings [Prosopis juliflora var. velutina (Woot.) Sarg.]. Maximum synergism between the carrier complex and herbicide occurred with the triethylamine salt of 2,4,5-T; relatively little influence on the butoxyethanol ester was observed. Picloram and 3,6-dichloro-o-anisic acid (dicamba) were intermediate in activity between the two phenoxy formulations.
