Abstract

Incidence and severity of the disease and resultant damage vary considerably among planting from one growing season to another.The genus Trichoderma are alternatives to chemical pesticides in agriculture as a biocontrol agent.The present study was undertaken to investigate the biocontrol potential of Trichoderma harzianum against the phytopathogenic fungus Rhizoctonia solani.Inoculum was applied as wheat bran preparation.Control of disease by Trichoderma were measured after 7,14,21 and 28 days.60-40% reduction in disease were recorded after 14 and 28 days.Decrease in Rhizoctonia solani was observed when the Trichoderma harzianum rate was increased from 10 6 to 10 8 log cfu g -1 soil.
