Abstract

Blue mold of pear caused by Penicillium expansum is one of the most significant serious destructive post harvest disease in India. Twenty three isolates of Penicillium expansum were isolated from rotted fruits of pear collected from APMC fruit market of Vashi, Navi Mumbai. Their sensitivity was tested against fludioxonil. It was found that Pe-10 was sensitive while Pe-17 resistant. MIC values ranged from 756.10- 972.30μg/ml. Sensitive isolate was selected for further studies and treated with chemical and physical mutagens and resistant mutant of Penicillium expansum (Pe-EMS-11) was found (4952.15g/ml). Total 14 homoeopathic medicines were selected for the control of fludioxonil resistant mutant of Penicillium expansum (EMS-Pe-11). Nux vomica was more effective PCE value (41.92) when used individually and in mixture with fludioxonil PCE value was increased as compared to individual (55.37) and followed by Arsenicum album, Sambucus nigra, Cynopodium, Baptisia tinctoria, Ustilago maydis, Iris versicolor, Zincum metallicum and Argentum metallicum.
