1990
Raksha, M.W.
The efficacy of five systemic insecticides, namely, diazinon, dicrotophos, dimethoate, phosphamidon and oxydemeton-methyl each at 0.1% a.i., was studied against the top shoot borer Ommatolapus haemorrhoidalis (Wiedemann) (Corculionidae: Coleoptera) of cane (Calamus tenuis Roxb.). The insecticides were applied as foliar spray on 3-years old cane plantation at the Cane Arboretum of Bangladesh Forest Research Institute, Chittagong. Each insecticide reduced pest population significantly against the unsprayed control. Phosphamidon and oxydemeton-methyl worked better in reducing the pest attack followed by diazinon, dicrotophos and dimethoate. No visible phytotoxicity was recorded for any insecticide tested.
