Influence of Trichoderma Harzianum Metabolites on the Development of Green Mould Disease in the Oyster Mushroom Abstract (original) (raw)
Green mould disease in Oyster mushroom (Pleurotus ostreatus) caused by Trichoderma harzianum results in considerable inhibition of growth of mycelium and fruit bodies of Oyster mushroom lowering the yield substantially. The study examined how mushroom growth is inhibited while T. harzianum growth is accelerated. Diseased mushroom bags were collected from mushroom houses within the Kandy district and T. harzianum was isolated. The most dominant strain was identified as T. harzianum biotype II (Th2) from the colony and growth characteristics. When the two fungi were grown on dual culture, T. harzianum overgrew the colonies of P. ostreatus rapidly. Diffusible metabolites produced by T. harzianum in culture significantly reduced the growth of P. ostreatus. Volatile metabolites of T. harzianum slightly stimulated the mycelial growth of P. ostreatus initially but P. ostreatus soon reverted to its normal growth. Growth of T. harzianum was not stimulated by P. ostreatus metabolites. Underst...
