Abstract:
Two experiments were performed using extracts of different botanicals possessing antimicrobial and antifungal properties. The plants used are viz. Mangifera indica, Olea europaea, Phyllantus emblica, Populus deltoides, Musa acuminata, Azadirachta indica, Terminalia arjuna, Bixa orellana, Sterculia alata. The effects of different leaf extracts was examined and observed against Curvularia and Meloidogyne incognita in In-vitro condition. All the botanicals tested against Curvularia sp showed strong inhibition property in suppressing the mycelia growth. When tested against Meloidogyne incognita it significantly increased the mortality on hatching of the J₂ juvenile. Populus (T₃) showed the strongest inhibition property against Curvularia sp while Bixa orellana (T₈) was most effective against M. incognita. The knowledge on efficacy of fungicides and nematicides bioagents in suppressing pathogen growth will help in implementing effective management strategy against Curvularia sp and Meloidogyne incognita.
