Abstract
Pears Pyrus communis L. collected from different sites of Kashmir Valley were found infected with Penicillium glaucum causing Penicillium rot. The diseased fruits appears light tan to dark brown. The decayed tissue becomes soft, watery and the lesion has a very sharp margin between diseased and healthy tissues. Decayed fruit has an earthy, musty odor. The pathogen was isolated and cultured on PDA medium for further fungal morphological observation and confirming its pathogenicity according to Koch’s postulates. Results of morphological data and pathogenicity test showed that the pears were infected by Penicillium glaucum Link resulting in Penicillium rot of pears. To our knowledge, it is the first report of pear fruit rot caused by P. glaucum in India. Study was also undertaken for the management of Penicillium rot of pear with some fungicides. It was revealed from the study that different concentration of fungicides brought about significant reduction in the mycelial growth and spore germination of Penicillium glaucum under in vitro conditions. Amongst the tested fungicides, carbendazim proved highly effective in inhibiting the mycelial growth and spore germination of Penicillium glaucum followed by hexaconozole, bitertanol and myclobutanil respectively. Higher concentration proved effective than lower concentrations.
