Main area of oil palm plantation is located in the Southern part of Thailand which has high amount of rainfall. Weed infestation is severe especially during young stage of oil palm. Main weed species in oil palm plantation are: Imperata cylindrica (L.) P. Beauv. Pennisetum setosum (Swartz.) L.C. Rich, Pennisetum pedicellatum Trin., Pennisetum polystachyon (L.) Schult., Paspalum conjugatum Berg., Rhynchelytrum repens (Willd.) C.E. Hubb., Eleusine indica (L.) Gaertn., Digitaria adscendens (H.B.K.) Henr., Brachiaria mutica (Forsk.) Stapf., Axonopus compressus (Sw.) Beauv., Dactyloctenium aegyptium (L.) P. Beauv., Echinochloa colona (L.) Link, Brachiaria distachya (L.) Stapf., Chloris barbata (L.) Sw., Paspalum scrobiculatum L., Ottochloa nodosa (Kunth) Dandy, Chromolaena odorata Linn., Melastoma malabathricum Linn., Lantana camara Linn., Borreia Laevis (Lam.) Griseb, Crassocephalum crepidioides (Benth.) S.Moore, Ageratum conyzoides Linn., Euphorbia heterophylla Linn., Tridax procumbens Linn., Boerhavia eracta Linn., Amaranthus viridis Linn., Euphorbia hirta Linn., Scoparia dulcis Linn., Physalis minima Linn., Hedyotis corymbosa (L.) Lamk., Phyllanthus amarus Schum and Thonn., Mikania cordata (Burm.f.) B.L. Robinson, Passiflora foetida Linn., Commelina benghalensis Linn., Merremia tridentata (L.) Hall, Nephrolepis biserrata (Sw.) Schott., Stenochlaena palustris (Burm.) Und. Bedd., Dicranopteris linearis (Burm.f.) and Lygodium flexuosum (L.) Sw. Weed management is very important to increase growth and yield of oil palm. It can be done in many ways: mechanical method, using cover crops, inter cropping and herbicide applications. The herbicide application shows higher growth rate of the plant, however, intergrated ways of doing resulted in increasing crop yield and lower the expenses.
