Potential of Aspergillus niger and Trichoderma viride as biocontrol agents of wood decay fungi

Abstract

Two biocontrol agents viz., Aspergillus niger and Trichoderma viride were tested against ten white rot and one brown rot wood decay fungi (WDF) by dual culture technique under laboratory conditions. The result showed that both A. niger and T. viride inhibit growth of all WDF tested. The percentage inhibition of radial growth values of T. viride and A. niger are almost the same (ranging from 29.2 to 66.7 %) and the average mean value of T. viride (51.7 %) is 13.3 % more than that of A. niger (45.5 %).
