Abstract

Six post harvest fungal pathogens viz. Pestalosia psidii (T1), Gloesporium psidii (T2), Rhizoctonia solani (T3), Fusarium sp. (T4), Alternaria alternata (T5), and Geotrichum candidum (T6)isolated from guava fruits were screened against essential oil of neem at 0, 1, 5, 10, 30 and 50% concentration by using poisoned food technique. The result indicated that neem oil was effective in inhibiting the mycelia growth against all the tested postharvest fungal pathogen of guava. It was observed that the inhibitory effect of oil is proportional to its concentration. The treatment with 1% oil did not significantly affect the radial growth of the fungus but at 5 and 10% conc. showed moderate antifungal activity against all the postharvest fungal growth tested. Neem oil showed the most significant reduction at 50%
concentration. Hence the result of the present investigation indicated that essential oil possessed antifungal activity in controlling the growth of postharvest fungal pathogen of
guava under laboratory condition and can be exploited as an ideal treatment for postharvest fungal disease management of guava.
