Abstract

Field experiments were conducted during 2011-12, at Agricultural Research Station, UAS, Dharwad, Karnataka, South India to know the efficacy of new molecules and botanicals against chilli pests. viz., green peach aphid (Myzys persicae Sulzer, Aphis gossypi Glover), thrips (Scirtothrips dorsalis Hood), yellow mite (Polyphagotarsonemus latus Banks) and fruit borer (Helicoverpa armigera Hubner). The results revealed that thiamethoxam 25WG @ 1 g/l, abamectin 1.8EC @ 0.5ml/l, diafenthiuron 50 WP @ 0.75g/l were highly effective for the management of chilli sucking pests. Against H. armigera, novaluron 10 EC @ 0.75ml/l, emamectin benzoate 5SG @ 0.4g/l and spinosad45SC @ 0.3ml/l were found quite promising. The pesticides from biological origin and neem based formulations might be relatively less harmful to the natural enemies than insecticide like imidacloprid and cypermethrin. Significantly increased yield (4.65 q/ha) was recorded in diafenthiuron 50 WP @ 0.75g/l with higher net returns (Rs 22,661/ ha).
