Use plant extracts for managing and increase the keeping quality of post-harvest banana rot in in vitro and in vivo condition

Abstract

Banana (Musa paradisiaca L.) is considered as the most popular fruit both in ripe and raw condition. Banana is highly perishable and post-harvest rot mostly caused by Colletotrichum musae which possess a great threat to ripe banana after harvest and in transit also causing 35% loss. In Dept. of Plant Pathology, Institute of Agricultural Science, SOADU, BBSR was conducted an experiment to get some solution about rotting of banana or Colletotrichum spp. To control or manage the post-harvest loss due to Colletotrichum spp we were tried different combination of plant extracts in vitro condition. Also we were tried alone and combination of plant extracts in vivo or field condition to increase the keeping quality. In in vitro condition Neem + Onion, Arakha + Garlic, Bael + Garlic retarded 100% radial growth followed by Morning glory + Begunia, Bael + Onion with 91.69% and 91.95% radial growth respectively in 20% concentration. Maximum control of post-harvest rot was observed in Begunia plant extract (56.90%) followed by Onion bulb extract (37.42%). Garlic clove extract (18.56%) was found to be least effective in controlling post-harvest rot of banana in field or in vivo condition.
