Screening of different botanicals extract on two polyphagous postharvest pathogens from mango and banana

Abstract

Aqueous extract of eight different locally available botanicals namely Eucalyptus globulus, Piper betel, Ocimum sanctum, Annona raticulata, Mikania micrantha, Asteracantha longifolia, Aegle marmelos and Murraya paniculata have been screened to evaluate their antifungal activity against two polyphagous postharvest pathogens Thielaviopsis paradoxa and Curvularia lunata from mango and banana. The results showed that all the botanicals extract significantly inhibit the mycelial growth as compared to control under in vitro. Murraya paniculata and Eucalyptus globulus showed best results as they inhibit maximum mean radial growth of T. paradoxa 92.70% and 73.86%, C. lunata 60.67% and 72.08% respectively. Sporulation of both the fungi reduced by these extract compared to control. The outcome of the study might be useful for alternative way to manage the postharvest disease caused by these pathogens.
