ABSTRACT:
In this research we studied the effectiveness of the Deuteromycetes, Penicillium expansum, Trichoderma viride, T.harzianum and Fusarium oxysporum against the Trametes versicolor that causes white rot on the wood. The effectiveness was evaluated in two ways, dual culture and volatile compounds. The results showed an inhibitory effectiveness of the anti-Deuteromycetes tested against T.versicolor fungus, the effectiveness differed depending on the type of anti-fungus and the method of study. The non-volatile compounds spread in the middle of the implant in the dual culture tests was more influential in the growth of T.versicolor. The T.harzianum fungus had the highest effectiveness in inhibiting the growth of wood spoiler fungus reaching inhibition rate of 68.23%, after it T.viride came at a rate of 66.70%, then the two fungi F.oxysporum, P.oxpansum at a rate of 40% and 28.82%, respectively. The effectiveness of Deuteromycetes differed depending on days of experience, and reached the highest percentage of inhibition in the ninth day of the search, and the growth of Deuteromycetes stopped in different days depending on the type of anti-fungus. Volatile compounds for all anti-Deuteromycetes showed stimulus effect for the growth of T. versicolor, rot fungi caused the deterioration of wood.
