Malabar neem (Melia dubia), which is locally known as “Malaivembu”. The tree is found in forest plantations in India and is a fast growing tree crop with up to 20 m height. It produces greater bio-mass in relatively shorter period. The present study was carried out to evaluate commercially available fungicides and bio-fungicides in-vitro, for their efficacy against foliar and soil borne pathogens. Firstly five promising fungicides and four biocontrol agents were evaluated against fungal pathogens under laboratory conditions. During in-vitro studies PDA amended with fungicides with different treatments at different inhibitory concentrations, almost completely inhibited the growth of pathogens at 1500 ppm with varying degree of success whereas Carbendazim being the most effective treatment with maximum reduction in mycelial growth of tested fungi as compared to other fungicides and control followed by combined fungicide carbendazim+mancozeb. While antagonistic biocontrol agents, Bacillus subtilis, Chaetomium globosum and Trichoderma viride are most effective against Pythium sp., and Pseudomonas fluorescens are effective against Phoma sp. Further field evaluations of the biocontrol agents and fungicides are required.
