Effect of several insecticide against oil palm pollinator’s weevil, Elaeidobius kamerunicus (coleoptera: curculionidae)
Study on the effect of pesticide application against Elaeidobius kamerunicus population was carried out in lab scale. The study was divided into two parts which are the direct effect against the weevil and indirect effect against the eggs. Cypermethrin showed the highest toxicity level compared to t...
