This study was carried out to investigate effect of CaCO3 treatment on cultivation of oyster mushroom for suppression of green mold disease and for promotion of mycelial growth to stabilize mushroom production in field and laboratory experiment. Treatment of CaCO3 in PDA media promoted mycelial growth of mushroom and suppressed that of green mold. Addition of CaCO3 in rice straw substrate increased mushroom mycelial growth compared with control. In that case, growth of green mold increased up to treated 0.6% CaCO3 but decreased in treatment beyond 0.8% CaCO3. There were some differences on effect of CaCO3 treatment according to green mold species. Trichoderma longibrachiatum was effected but T. virens was not effected by treated CaCO3. Differences among mushroom strains by treated CaCO3 were not shown. It is confirmed that treatment of CaCO3 can promote mushroom mycelial growth but it's not clear in the field. In the result of field test, treatment of CaCO3 in rice straw substrates tended to increase yield and decrease incidence of disease compared with non-treatment. These results suggest that CaCO3 treatment on cultivation of oyster mushroom can be applied to take preventive steps against of green mold disease.
