In vitro screening of six extract of plant species viz. Azadirachta indica, Datura metel, Lantana camara, Parthenium hystorophorus, Ociumum spp., Argimone mexicana and five bioagents viz. Trichoderma harzianum, T. viride, Aspergillus niger, Penicillium citrinum and Gliocladium virens were tested against Stemphylium botryosum. Among plant extracts Azadirachta indica (66.5 per cent) and Datura metel (64.5 per cent) were the best in restricting the growth of pathogen over control and in evaluation of bioagents, S. botryosum + T. harizianum (81.2 per cent) and S. botryosum + T. viride (74.5 per cent) were significantly inhibited the growth of pathogen. Under field condition suppression of pathogen by T. harzianum, treating the garlic cloves (0.2 per cent) along with two foliar sprays (0.2 per cent) at 15 days interval found to be most effective for management of this disease.
