Abstract
The application of glyphosate herbicide was chosen to control weeds because it had a broad spectrum.Rain is one factor that can reduce the effectiveness of glyphosate herbicides while the addition of surfac-tants in glyphosate herbicide applications can increase the effectiveness. The purpose of this researchwas to determine the effect of addition of surfactants and the time of rainfall after herbicide applicationand their interaction with the efficacy of glyphosate herbicide. This research used a split plot design with14 treatments and 5 replications tested on weeds (Paspalum conjugatum, Setaria plicata, Asystasiagangetica, Praxelis clematidea, Cyperus rotundus, and Cyperus kyllingia). The main plot is withoutsurfactant and surfactant addition of 0.1% and subplot is time of rainfall after application with the timeof rainfall is 0, 1, 2, 3, 4 hours, and no rainfall after application. The datas were analyzed of variance andfurther tested with the Least Significant Difference test (LSD) level of 5%. The results showed that theaddition of surfactant can increase the efficacy of glyphosate herbicide, and the rain fall time afterapplication can reduce the efficacy of glyphosate herbicide. The addition of surfactant to the applicationof glyphosate herbicides followed by the rain after application has higher efficacy compared to the herbi-cide application without surfactants.
