Abstract: The aim of present study was evaluation of mycelial growth of Pleurotus sapidus against different botanicals extract in laboratory. The study was conducted during September 2018 at Mushroom Laboratory Department Plant Pathology, S. V. P. University of Agriculture and Technology, Meerut, UP, India. In-vitro evaluation of Pleurotus spp. were conducted seven treatment with four replication. The Petri plates were incubated at 23±2°C for 9 days and observations were recorded at each 72 hrs. All plant extracts were founded more or less mycelial growth of mushroom. Maximum growth was observed after nine days lantana leaf extract @ 4% (88.25 mm) followed by lantana leaf extract @ 2% (87.25 mm) and 82.25 mm in control without extract. The Eucalyptus was recorded less or inhibited the mycelial growth of Pleurotus (15.75 and 46.00 mm) @ 4 and 2 percent of Eucalyptus extract respectively. The lantana leaf extract was found very fast growth of P. sapidus mycelium.
