| Abstract:
Management of blue mould rot (Penicillium italicum) of Kinnow fruits explored using biocontrol agents viz. Trichoderma, Gliocladium, Bacillus, Pseudomonas, Debaryomyces, and Sporidiobolus spp. revealed variable efficacy in vitro. On further testing as pre- and post-inoculation treatment, the yeasts showed an edge over other fungal and bacterial spp. with D. hansenii and S. pararoseus exhibiting 89.12% and 84.12% as pre-inoculation, and 86.37% and 78.26% as post-inoculation treatments, respectively. In general, the pre-inoculation treatment proved more effective perhaps by out-competing post-inoculated (harvest) pathogen(s) for space and nutrients. The yeast strain S. pararoseus (KFY-1, MTCC No. 8377, IMTECH, India) has not been recorded so far on Kinnow fruit, hence this seems to be a new record from Rajasthan, India. Further studies are in progress. | |
