ANTIFUNGAL ACTIVITIES OF SEED EXTRACTS OF MAHOGANY ON CARICA PAPAYA (PAWPAW) FRUIT ROT IN MUBI, ADAMAWA STATE
Journal Title: World Journal of Pharmaceutical Research - Year 2018, Vol 7, Issue 7
Abstract
Pawpaw (Carica papaya L.) fruit production has become an integral part of daily life as a source of food, vitamins and minerals which is one of the most popular, cheapest, economically important fruit tree grown in Nigeria. The study of the fungi associated with postharvest rot of Carica papaya fruit were carried out in three different markets of Mubi North and South Local Government Area of Adamawa State (Kuturu Market, Mubi Main Market and Mubi New Market) from June to November, 2016 to test for both invitro and invivo antifungal efficacy of seed extracts of Khaya senegalensis. Sample of papaya fruits were collected, and industrial PDA was used for the isolation of the fungi pathogens. Four fungal pathogens were isolated from papaya fruits and were identified as Rhizopus stolonifer, Botryodiplodia theobromea, Aspergillus niger and Mucor spp. Control trials using seed extracts of Khaya senegalensis was conducted at six different concentration levels (0%, 20%, 40%, 60%, 80% and 100%). Incidence of rot showed that Kuturu Market had the highest with 26.77%, followed by Mubi Main Market (20.77) and then Mubi New Market (20.20). Results obtained from the control trials with seed extracts of Khaya senegalensis both invitro and invivo showed significant differences (p>0.001) and was effective in inhibiting fungal growth although with variation in their effect.
