Evaluation of Crude Extracts of Trametes versicolor (L.:Fr.) Pilát to Control of Phytopathogenic Fungi

The antimicrobial activity of crude extracts of Trametes versicolor was evaluated to control of phytophatogenic fungi using as solvents Water, Hexane, Ethanol, Dichloromethane and Acetone. Concentration of 0, 10, 20, 30 and 50% (v/v) of each extract were evaluated on PDA culture medium using filter paper disks of 6 mm of diam with 60 µl of each concentration. The diffusion area between disks with each concentration of extracts and the fungi growth was recorded at 48, 72, 96, 120, 144 and 166 h after incubation. The extracts obtained from the Hexane and Dichloromethane solvents at concentration of 20, 30 and 50% showed the highest inhibition of the development of Rhizoctonia solani, Fusarium moniliforme, Botrytis cinerea, Cercospora capsici and Alternaria solani above Ethanol and Acetone while the aqueous extract was the least efficient in any of the concentrations evaluated.
