G. Rajendran, Vara Saritha

Abstract

Plant extracts of Arnica montata, Calendula officinalis, Carica papaya, Azadirachta indica were evaluated for their nematicidal effect against Meloidogyne incognita infesting tomato cv. PKM 1. All the plant extracts tested were found to reduce the root galls and soil population. Maximum mortality was recorded in plants treated with A. indica at 30 dilution.
