Insecticides from different groups having contact and systemic action were evaluated against sunflower mealy bug during 2007–08 to 2009–10. Dichlorvos 76% WSC having fumigant effect along with contact and stomach action @ 2 ml l−1 of water was found effective for the management of mealy bug followed by methomyl 40 SP 400 gai ha−1 (1.00 g l−1), a broad spectrum, quick knock down effect. Dichlorvos 76 WSC also showed maximum yield and incremental cost benefit ratio (1:7.60) followed by methomyl 40 SP.
