Bioefficacy and Shelf Life of Conidial and Chlamydospore Formulations of Trichoderma harzianum Rifai


  • Project Directorate of Biological Control (ICAR), Bangalore, Karnataka, 560 024, India


The conidia and chlamydospores of Trichoderma harzianum produced by solid state and liquid fermentation, respectively, were formulated as powder and tested for their comparative bioefficacy and shelf life. Both the propagules did not differ significantly in reducing root rot incidence in chickpea caused by Rhizoctonia solani. Conidial formulation retained optimum amount of viable propagules (>106 cfu/g) even after 180 days of storage at room temperature but in chlamydospore formulation, viable propagules reduced to less than 106 by 150 days.
