Abstract:
Pomegranate is regarded as a fruit of paradise but the scab disease is spreading in pomegranate field and damage the crop, there is a lack of information on management of scab of pomegranate. Fungicides viz., thiophanate methyl, carbendazim, tebuconazole and propiconazole showed hundred per cent mycelial growth inhibition at 250, 500 and 1000 ppm. However, difenoconazole at 1000 ppm concentration showed hundred per cent inhibition of S. punicae. Among the contact fungicides, propineb and mancozeb were showed hundred per cent mycelial growth inhibition at 1000 ppm concentration. Among combi-products maximum inhibition of mycelial growth (100 %) was noticed in case of azoxystrobin + mancozeb, hexaconazole + zineb, fenamidone + mancozeb and carbendazim + mancozeb at all the three concentration (250, 500 and 1000 ppm) tested. Among the nine plant extracts evaluated, maximum fungal growth inhibition (73.63 %) was observed in garlic extract, which was significantly superior over all other botanicals tested. Among the fungal bio-agents tested, Trichoderma harzianum (Th-41) showed 83.15 per cent inhibition of the pathogen. Similarly, among the bacterial bio-agents tested, maximum inhibition was observed in Bacillus amyloliquefaciens (64.60 %).
