Abstract

In present investigation, attempts were made for detailed survey of Penicillium induced post-harvest losses during different months of its markets in Coochbehar. It was found from survey that a total of Rs. 48,490 and Rs. 4,33,650 was lost due to post harvest transit, storage at market level in Pundibari and Coochbehar Sadar market, respectively. Green mold and blue mold, caused by Penicillium digitatum and P. italicum, respectively contributed 20–30% of the total post harvest losses during the months of November to February. The incidence of disease increased from November to January causing nearly 2.6–3.9% of monetary loss in Pundibari market. Sharp decrease in TSS, total sugar and peel thickness and rise in titrable acidity was observed with increase in disease incidence.
