Trichoderma harziaum is known to cause green mold disease. As a result, the quality and quantity of mushroom farms are deteriorating, and eco-friendly materials rather than chemical pesticides are needed to manage this. This experiment is an important strategy to solve problems of environmental pollution and pesticide residues and realize sustainable agriculture. Accordingly, research was conducted to select an eco-friendly T. harziaum control agent that does not affect the growth of Pleurotus ostreatus var. Heuktari. As a result of the experiment, the growth rate of T. harziaum decreased by 92% and 71.8% in media treated with 5000ppm and 1500ppm Lemongrass, respectively, compared to untreated Potato Dextrose Agar (PDA) media. Rosemary 5000ppm decreased by 22.2%, and Lavender 5000 and 1500ppm decreased by 44% and 14%, respectively. Red pine decreased by 1.2% and Cypress decreased by 2.4%. Meanwhile, it was confirmed that the growth rate increased when 1500ppm of Rosemary and 1500ppm of Eucalyptus were added. Like T. harziaum, Heuktari growth rates increased at 1500ppm for Rosemary and Eucalyptus. In addition, it was confirmed that the growth rate increased even at 1500ppm of Red pine. In conclusion, Lemongrass treatment is most effective in controlling T. harziaum, but it also reduces the growth rate of Heuktari. Therefore, it was confirmed that the most suitable pest control material using eco-friendly materials is Red pine 1500ppm.
