ABSTRACT
Mucuna bracteata and Cymbopogon citratus are fast-growing plants, easy to find and contain various secondary metabolites. Therefore, these two types of plants can be used as an alternative bioherbicide for weed control. This study aims to determine the effect of aqueous extracts from fresh leaves of C. citratus, M. bracteata and a mixture of both on the germination and growth of Paspalum conjugatum and Borreria alata weeds.Treatments consisted of extracts of M. bracteata, C. citratus and a mixture of both extracts at various concentrations (0% or control, 20% and 60%). Spraying of the extracts started at the time of seed planting, then spraying was done every 3 days for 30 days. All aqueous extract treatments showed toxicity effects on weeds as indicated by the inhibition of germination and growth of P. conjugatum weed and B. alata weed. Mucuna bracteata extract was more effective than C. citratus extract. The mixed extract (C. citratus + M. bracteata) was more effective than the single extract. The highest percentage of germination and growth inhibition was found in the single extract of M. bracteata and mixed extract (M. bracteata + C. citratus) with concentrations of 40% and 60%. Based on the results of this study, 40% fresh extract of M. bracteata or 40% mixed extract of C. citratus + M. bracteata can be applied by spraying directly to the field to inhibit weed emergence and weed growth in agricultural land as an alternative weed control.
