Weeds in oil palm plantations include any plant or vegetation that in any way interferes with the production of palms, resulting in a reduction in yield or quality. Alocasia sp. (wild yam) is a common weed at oil palm plantation in Borneo, Malaysia. This study was conducted to evaluate commercial herbicides’ effectiveness (amine, ally, glyphosate, and paraquat) against Alocasia sarawakensis , Alocasia robusta , and A. macrorrhizos . Cocktail herbicide showed faster wilting, scorching and rotten and least/late regeneration within 30 days of monitoring. Combination of two chemicals reacted better and potentially long-lasting, and further observation can provide info on the difference between (systemic+contact), (contact+contact) and (systemic+systemic). Cost-effectiveness analysis showed herbicides cocktails Treatment 9 (amine + ally + surfactant), Treatment 11 (amine + paraquat + surfactant), and Treatment 12 (ally + paraquat + surfactant) were the most cost-effective (±RM0.58 cent/16 L) to control Alocasia sp. This study’s finding would give an alternative solution for oil palm plantation to control weed, especially Alocasia sp.
