Investigations on the effect of Plant extracts and Neem products and their combinations on the activity of pests of chilli Fruit borer Helicoverpa armigera carried out during 2012-213 and 2013-2014 kharif seasons at the Karchal village of Medak District, Telangana state. The experiment was laid out in RBD (Randomized Block Design). The spray schedule treatment (T3) was found to be the most effective against the fruit borer H.armigera. In this, 2 sprays of Nimbecidine (NB) (5ml/l) at 2 and 5 WAT (Weeks After Transplanting), 2 sprays of 5% Custard Apple Leaf Extracts (Cae) at 7 and 11 WAT and Neem Oil (NO) (5ml/l) at 9 WAT, were applied, recorded a least fruit borer.
