New environmentally safe insecticides with novel modes of action were evaluated for the management of Chilo partellus (Swinhoe) on maize during kharif 2013 and 2014. Neem 1% (Neem ban) @ 500 mL ha−1, flubendiamide 480 SC (Fame), novaluron 10 EC (Rimon) and fipronil 5 SC (Regent), each @ 75, 100 and 125 mL ha−1 respectively along with deltamethrin 2.8 EC (Decis) @ 200 mL ha−1 as standard check were sprayed after 14 days of crop germination. The mean leaf injury incidence was on par at the respective doses in flubendiamide 480 SC (1.392.58%), novaluron 10 EC (2.01–2.94%) and fipronil 5 SC (2.36–3.67%) but significantly less than untreated control (9.58%). Mean dead heart incidence was on par at different doses in flubendiamide 480 SC (3.90–5.34%), novaluron 10 EC (4.93–6.93%) and fipronil 5 SC (5.59–7.20%) but significantly lower than the untreated control (14.09%). The dead heart incidence in neem formulation was 8.53%, which exhibited some degree of efficacy in comparison to untreated control. The grain yield was significantly better with the newer insecticide treatments (60.41--64.18 q ha−1) than neem formulation (57.18 q ha−1) and untreated control (54.58 q ha−1). These insecticides at the dose of 75 mL ha−1 could be utilized as effective tool in C. partellus management in maize.
