abstract
A field experiment was laid out at Nevanagere village of Sirsi, Uttar Kannada, Karnataka, India during 2013-2014 cropping season on evaluation of EC formulations against arecanut white grub, Leucopholis lepidophora Blanchard. The results revealed that, at 60 days after imposition of treatment chlorpyriphos 20 EC @ 10 ml per palm was the best treatment at all observation periods followed by rynaxypyr 4G @ 25 g per tree. However, among the EC formulations M. anisopliae Novozyme @5×10⁹ (3ml/lit), M. anisopliae T-stanes @1×10⁹ (3ml/lit) and M. anisopliae Novozyme @5×10⁹ (2.5ml/lit) effected highest mortality viz., 100.00, 97.87 and 94.44 respectively as compared to lower dose of M. anisopliae T-stanes @1×10⁹ (2ml/lit), M. anisopliae Novozyme @5×10⁹ (2ml/lit) and dust formulation of M. anisopliae @1×10⁸ (5kg/acre) with 84.44 and 83.33 percent mortality.
