Effect of different insecticides and bio extracts was studied against maize stem borer Chilo partellus (Lepidoptera: Pyralidae). The experiment was conducted at the farm of Cereal Crop Research Institute (CCRI) Pirsabaq, Khyber Pakhtunkhwa, Pakistan during July to September, 2014. Four treatments Refree® @1kg/acre, Neem extract@ 5%, Lannate25SP® @ 350g/100L, garlic extract @ 10% along with control plot, replicated three times. It was concluded from the study that synthetic insecticides Refree® and Lannate® proved to be best and show higher biological efficiency (47.46) and (44.05) respectively as compared to bio extracts (neem, garlic). The neem extract gives better results than garlic extract@10% and control plot. Therefore Lannate® and Refree® are recommended for quick and best control of maize stem borer in maize crop.
