Evaluation of antagonistic potential of Trichoderma harzianum isolates against Fusarium Moniliformae causing pokkah boeng of sugarcane

In an attempt to develop effective biocontrol system for the management of pokkah boeng caused by Fusarium moniliformae, five isolates of Trichoderma harzianum viz., Th-5, Th-9, Th-10, Th-28 and Th-32 were tested for their antagonistic potential against F. moniliformae. Results recorded that the strains were found effective in inhibiting the mycelial growth. Maximum percent inhibition was recorded in Th-28 (42.94%) followed by Th-32 (41.17%), Th-10 (39.21%), Th-9 (31.17%) and least in Th-5 (30.00%) as compared to control. The little difference in percent inhibition of mycelial growth indicates the difference in their efficacy against the pathogen.
