Allelopathic Potential of Edible Gingers Against Weeds


Medicinal and Aromatic Plants Seminar (MAPS 2008)


21st October - 22nd October 2008

Place Held

The Legend Hotel, Kuala Lumpur


Current agricultural practices involved in weed management rely strongly on the use of synthetic herbicides. Therefore, an alternative approach such as the use of natural product-based weed management consists of having crops produce their own phytotoxins to prevent or suppress the growth of competing weeds should be taken into consideration. The study aims to assess allelopathic potential of four edible gingers on seed germination of invasive weeds. The gingers used were Etlingera coccinea (Blume) S. Saki & Nagam. (tuhau), Curcuma longa L. (turmeric), Lan guas galanga (L.) Stuntz (greater galanga) and Zingeber officinale Roscoe (ginger). Three invasive weeds included in the study were Imperata cylindrical, Paspalum conjugatum and Cyperus pilosus. Weed seed bioassay was performed using hexane and methanol extracts of the gingers. The future of weed management would probably be significantly influenced by natural products research. This study was an effort to harness the power of natural products for weed management.
