Antifungal activities of different plant extracts against pink mold of banana caused by Trichothecium roseum (Pers.) Link

Abstract

Trichothecium roseum (Pers.) Link causes pink mold rot in banana fruits across the world. Due to this infection, 30% of losses arise in poor man’s food. To control this disease, plant extracts show an alternative to fungicides. In this study, 40 plant species were screened for their antifungal activity against T. roseum. Among 40 hot and cold aqueous extracts of plant species, only 10% Allium sativum and 6% and 8% of Mansoa allicea showed 100% inhibition of T. roseum. Freezing condition (4°C) shows 100% inhibition compared to room temperature (27°C) and incubation temperature (46°C). One hundred per cent inhibition of T. roseum was observed within 5 days compared to 15, 20 and 30 days of incubation. The pink mold of banana caused by T. roseum was reported for the first time in Karnataka.
