Relative efficacy of granule insecticides for the management of Chilo infuscatellus (Lepidoptera: Pyralidae) in Pakistan

The study was planned to find out the relative efficacy of granule insecticides against the sugarcane stem borer, Chilo infuscatellus Snellen. The experiment was laid out in a randomized complete block design and replicated thrice with a plot size of 5×10 m^2 with five treatments. Four insecticides viz., Furadan (2,2-dimethyl-2,3-dihydro-1-benzofuran-7-yl methylcarbamate), 3G Carbofuran @ 12 kg ha^-1, Padan (S -2-dimethylaminopropane- 1,3-diyl) 4G Cartap @ 10 kg ha^-1, Thimet (O,O diethyl S ethylthiomethyl phosphorodithioate) 5G Phorate @ 10 kg ha^-1 and Monomehypo (Dimethyl- hydro-2-(1,3 monosodium disolfonat thio prpopya l0 ammomonium) @ 8 kg ha^-1 were applied. Minimum infestation of sugar cane stem borer was observed after the treatments with Furadan (10.22%) followed by Thimet (11.35%), Padan (12.45%) and Monomehypo (13.84%) when compared with the control (26.13%). Findings of the present study could be helpful in the chemical based management of sugarcane stem borer using Furadan.
