Trichoderma spp. widely used as biocontrol agents for controlling a wide range of plant diseases. Banana anthracnose caused by Colletotrichum musae is a prominent, widely distributed postharvest disease. This study was carried out to assess the effectiveness of locally isolated Trichoderma virens against C. musae and the mass production of T. virens using locally available, low-cost solid substrates. T. virens was tested for the inhibition of C. musae isolate in-vitro and in-vivo by dual plating and inoculating into two varieties of ripened banana: Kolikuttu and Cavendish, respectively. For mass production, T. virens was inoculated into different solid substrates including scraped coconut waste, sawdust, tea waste, seeds from rice, finger millet, and maize, dried pieces of water hyacinth plant, paddy straw, and Panicum maximum leaves; regularly taken spore counts (cfu/g) and checked for viability by plating after 12 weeks of storage. The pathogen inhibition percentage by T. virens was 74.10%. Disease severity was 0% in Kolikuttu and 19% in Cavendish after 5 days of T. virens spore application (1x107 spores/ml). Significantly higher (p≤0.05) mean spore production resulted in rice seeds (9.345x109 spores/g) compared to the other substrates and the least resulted in sawdust (1.808x109 spores/g) at the 8th week after T. virens inoculation. Spores of T. virens were viable in all the tested substrates throughout the study period. The results conclude that T. virens is capable of controlling banana anthracnose and can be efficiently mass- produced by using rice seeds, dried pieces of P. maximum leaves, and finger millet seeds as substrates. http://doi.org/10.4038/tar.v34i2.8621 2022-09-01T00:00:00Z http://repository.rjt.ac.lk/handle/123456789/5629 Design and Development of a Closed Cycle Heat Pump Drying System for Industrial Drying of Rice and Chili Ekanayake, E.M.A.C.; Amaratunga, K.S.P.; Kariyawasam, H.K.P.P.; Fernando, A.J.; Abeyrathna,R.M.R.D. 2019-01-01T00:00:00Z http://repository.rjt.ac.lk/handle/123456789/5628 Pulse-Width-Modulation Control of a Heat Pump Dryer with Cascade Evaporators and Parallel-Flow Condensers Fernando, A.J.; Amaratunga, K.S.P.; Dharmasena, D.A.N.; Abeyrathna, R.M.R.D.; Gajasinghe, I.L.; Weerakoon, H.S.T.; Ekanayake, E.M.A.C.; Bandara, D.M.S.P. 2022-01-01T00:00:00Z http://repository.rjt.ac.lk/handle/123456789/5627 Modeling Employees Behavior Intention with the Adoption of a Suggestion System for Lean Initiatives Chopra, Shweta; Fernando, Jayaruwani 2020-01-01T00:00:00Z
