Abstract

Activity and effectiveness of insecticide mixtures (thiodicarb and triflumuron)  against physics caterpillar pests  Metisa plana  on oil palm plantation.  The objectives of this study were to evaluate the joint action of thiodicarb and triflumuron insecticides  in the laboratory,  and to determine their effectiveness  in supressing population of  M. plana  in the field.  The mortality bioassays were conducted by a spraying method. The results showed that the inseticide mixtures between thiodicarb and triflumuron  possessed a sinergistict activity against  M. plana  larvae with insecticide combination index of 0.49%. Iinsecticide mixtures  at a range dose of  250 - 1250 ml/ha  spraying on oil palm planst effectively suppressed population of  M. plana  larvae.
