Studies on the Effect of Vinyl Mulching on Pleurotus Cultivation: Control of Mushroom Diseases on Pleurotus ostreatus (II)

ABSTRACT

Perforated vinyl mulching technique was performed on oyster mushroom beds for controlling mushroom diseases. Mycelium under vinyl sheets were safely protected from outside undesirable microorganisms. One of two mushroom farms showed 75% of disease incidence, the other 40% and National Institute of Agricultural Science and Technology (NIAST) 13% in the conventional growing method, whereas 12%, 14%, and 5% in the vinyl mulching cultivation method. Waterlogging caused mushroom bed worse, and Trichoderma spp. were infested on the conventional mushroom bed. Disease incidence investigated in other case was 25% to 30% in the conventional growing method, whereas 5 to 9% in the vinyl mulching cultivation method. Yields in conventional method were 6.5 to 7.2 kg/m2 and those in vinyl mulching method were 7.6 to 8.1 kg/m2. So it was suggested that vinyl mulching technique was good for prevention from disease and elevation of productivity.
