      The chemical pesticides have an adverse effect on the human health and environment, Its necessary find alternatives naturally organic compound safe and non-toxic of natural plant extract to control the green disease that caused by Trichoderma longibrachiatum that infect oyster mushroom causing Large economic losses for this crop. The organic compound was manufactured using the ethanoic alcohol of the licorice plant (Glycyrrhiza spp), the cinnamon plant (Cinnamomum spp), and lime by using the dried powder of each plant with the lime. and the resulting concentration was concentrated and applied at a concentration of 2% against the green mold caused by the fungus Trichoderma longibrachiatum on the oyster mushroom Pleurotus eryngii. Field experiments showed an increase in the number of fruiting bodies, the amount of yield, and an increase in the biological efficiency of the culture media, which confirms the dual role of the organic compound in suppressing the pathogen and promoting the growth of oyster mushrooms. These results indicate this compound as an effective and sustainable alternative to chemical fungicides in controlling green rot disease.
