| Abstract/Contents: | "The effect of two glyphosate formulations (R and RII) applied alone or in combination with organosilicone surfactants was studied on three grass species in the glasshouse. Without surfactants, the efficacy of glyphosate-R on perennial ryegrass (Lolium perenne) and prairie grass (Bromus willdenowii) was significantly higher than glyphosate-RII. Addition of organosilicone surfactants decreased in herbicidal effect of glyphosate in most cases. Retention of glyphosate on foliage varied with grass species and formulation. Experiments conducted with 14C-glyphosate investigated the effect of formulation and organosilicone surfactants on uptake and translocation in perennial ryegrass and prairie grass over a 72-h time- course. 14C-glyphosate concentrations in young plant tissues and roots were also measured. There were no significant differences between the two formulations in uptake and translocation. Adding organosilicone sufactants antagonized uptake and translocation, decreasing the concentration of 14C-glyphosate in young plant tissues." |
