In two pot experiments radioactive paraquat was applied to certain important veld grasses (Experiment I -Aristida junciformis, Themeda triandra, Elyonurus argenteus, Andropogon filifolius, Eragrostis curvula ; Experiment II -A. junciformis, E. argenteus) to determine the extent of translocation at a young stage of growth and with treatment at different times of the day. In the first experiment movement occurred in all grasses along the length of the treated leaf, while in E. curvula and A. filifolius the herbicide was translocated to other leaves also. The second experiment indicated the importance of application of paraquat at. 1700 hours for maximum translocation.
UITTREKSELMet twee potproewe is die omvang van translokasie van paraquat by verskeie belangrike grassoorte (Proef I -Aristida junciformis, Themeda triandra, Elyonurus argenteus, Andropogon filifolius, Eragrostis curvula ; Proef II -A. junciformis, E. argenteus) bepaal. Radioaktiewe paraquat is toegedien in 'n jong groeistadium en by verskillende tye gedurende die dag. In die eerste proef is beweging in die lengte van die behandelende blaar by al die grasse waargeneem. By E. curvula en A. filifolius het translokasie na ook ander blare plaasgevind. Die tweede proef het die belangrikheid getoon van toediening om 1700 uur maksimale translokasie.
