Abstract
Herbicides remain the major strategy for weed control in oil palm plantations although some biological mechanical and cultural methods are being practiced though limited. However heavy reliance upon herbicide as primary method of weed control has resulted in evolution of herbicide-resistant weeds. Currently a total of 10 weed biotypes have developed cross or multiple herbicide resistance in oil palm plantation or nurseries. Most of these weed biotypes are resistant to glyphosate paraquat and ALS inhibitor. Four weed species namely Eleusine indica Clidemia hirta Hedyotis verticilata and Chromolaena odorata are resistant to these herbicides in several states of Malaysia including Terengganu Kelantan Pahang Kedah Selangor Pulau Pinang Perak Johor and Sarawak. Herbicide mixture has been recommended to delay the evolution of herbicide resistance. Criteria for effective mixtures for resistance management in oil palm plantations are discussed.
