The prevalence rates of these agents were determined. Among the isolated disease agents, the most common were Mycogene perniciosa, the agent of wet bubble disease; Verticillium fungicola, the agent of dry bubble disease; Trichoderma spp., the agent of green mold; and Pseudomonas tolaasii, the agent of bacterial brown blotch disease. The antifungal and antibacterial activities of different doses of essential oils from rosemary (Rosmarinus officinalis), cumin (Cuminum cyminum L.), basil (Ocimum basilicum), fennel (Foeniculum vulgare), and black thyme (Thymbra spicata L.), which are used as spices to control the isolated disease agents, were tested in vitro on PDA (Potato Dextrose Agar) and NA (Nutrient Agar). Doses of 1, 10, 50, 100, 250, 500, and 1000 ppm of these essential oils were tested against the pathogens. Sterile deionized water served as a control. The lowest doses of thyme oil (50 ppm) were found to cause wet bubble disease, while 100 ppm thyme oil was associated with dry bubble and green mold pathogens. Additionally, 1000 ppm thyme oil exhibited antibacterial activity against P. tolaasii. Cumin, basil, and rosemary essential oils showed different effects against various pathogens. Fennel oil, on the other hand, was effective at 500 ppm against Trichoderma spp., M. perniciosa, and P. tolaasii, while at 1000 ppm it was effective against V. fungicola. The antifungal and antibacterial effects of rosemary, basil, cumin, thyme, and fennel oils are believed to stem from their distinct active ingredients. A detailed study of these active compounds could lead to promising results for pathogen control. In practice, minimizing pesticide use and employing low doses of these essential oils which are safe for human health will play a crucial role in reducing pesticide residues on edible cultivated mushrooms, especially those consumed raw.}, number={2}, publisher={Bingol University}
