Abstract<\/strong><\/p>\n\n\n\n

A laboratory studies were conducted during 2018\/2019\nseason at Plant Protection Department, Faculty of Agriculture, University of\nTikrit. The study investigated the bio-synthesis of the nanoparticles of an\nedible mushroom Pleurotus<\/em> ostreatus\n<\/em>A2019 using four\nfractions including fungus filtrate, biomass, hot extract and cold extract of\nthe biomass. The\nresults of the laboratory study indicated that the formation of silver\nnanoparticles from the Pleurotus<\/em> eryngii<\/em>,_by\ndetecting the chromatic heterogeneity of these four fractions from yellow to\nbrown, and recorded the highest absorption peaks (using the spectrophotometer)\nof the silver nanoparticles of all fractions within wavelengths ranged from 350\nto 475 nm . All concentrations and fractions of prepared Ag nanoparticles\nshowed the highest inhibition growth against pathogenic fungus P.<\/em> <\/em><\/strong>aphanidermatum<\/em> in comparison to control. The\nhighest inhibition of linear growth was recorded at a concentration of 1.5 mM\nin the fungus filtrate treatment as it reached 0.66 mm, while the effect of\nconcentration of 0.5 mM in the hot extract treatment of the biomass recorded\nthe lowest inhibition linear growth 0.15 mm with significant differences\nbetween them. While the filtrate treatment showed significant superiority with\nthe other treatments and it reached 0.42 mm compared to the other transactions,\nwhere the treatments of the cold and hot aqueous extract and biomass recorded\n0.36, 0.16, 0.24 mm respectively. <\/p>\n\n\n\n
