Abstract

Weed control is one of the important maintenance activities in plant cultivation to stabilize the quantity and quality of crop yields. Unfortunately, spraying synthetic herbicide is still the main choice to solve this risk. Improper use can increase environmental damage. Therefore, the development of bioproducts from plants by utilizing their toxic properties is considered to be able to act as an eco-friendly biocontrol. This study aims to determine the potential of Praxelis clematidea extract of different plant parts on the seed germination, seed mean germination time (MGT), and sprout morphology of Asystasia gangetica weed. The study was conducted by bioassay test using a completely randomized design (CRD) in germination room to explore the effect of Praxelis water extract from the aerial part (including stems; leaves; and flowers), non- aerial part (including basal stems and roots), and whole plant. Whole plant extract suppressed germination and MGT higher than extract derived from aerial and non-aerial parts. The result was also supported by results of color changes observation, which showed browning in the roots, cotyledons, and hypocotyls of Asystasia treated seedling. Thus, Praxelis extract using all parts of the plant is the optimal formula for bioherbicide against Asystasia, as weeds in Palm oil plantation.
