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

Shahbaz Ahmad

Abstract


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 m2 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.
