  • Two oyster mushroom varieties MDU 1 and MDU 2 were released during the year 1997 and 2000.
  • Management of Papaya stem rot / foot rot : Soil application of VAM @ 10kg /ha + neem cake 150 kg/ ha as basal + soil application Trichoderma viride @ 5kg /ha 30 DAP + soil application of Pseudomonas fluorescens @ 2.5kg /ha 60 DAP recorded the lowest disease incidence of papaya foot rot/ stem rot (8.79%) with maximum disease reduction of 86.48 per cent over control.
  • For Composting banana sheath waste, the chopped and dried banana sheath wastes inoculated with Pleurtous djamor @1 kg of culture added with 5 kg Urea for 1 tonne of waste caused significant reduction in C:N ratio (22.8) when compared to undecomposed banana sheath waste (34:1) on 40 days after inoculation
  • Management of Jasmine (Jasminum sambac Aiton) leaf blight caused by Alternaria jasmine: Spraying of Pseudomonas fluorescens Pf3 (0.2%) recorded the maximum leaf blight disease reduction of 74.54 per cent. It also recorded the highest yield of 127.56 kg/15 cents (flower buds produced for 45 days) as against the control which recorded the yield of 85.47 kg / 15 cents.
  • Management of Anthracnose of common beans using Plant Growth Promoting Rhizobacteria : Seed treatment with  Pseudomonas fluorescens (PNRG1) + Bacillus subtilis (BMACG1)@10g each/kg of seed + foliar application of both @ 0.2% recorded minimum anthracnose disease intensities of 6.08 and 5.31  per cent in the field trials conducted as against 40.78 and 41.30 in controls, respectively. The above treatment also recorded a significantly higher pod yield of 9.21 and 9.23 tonnes/ha as against 8.0 and 7.6 tonnes/ha in control respectively.
  • Strategies for enhancing yield efficiency in Oyster mushroom (Pleurotus ) Supplementation of paddy straw beds with cotton seed cake (4%) (organic) boosted the oyster mushroom yield.
