Abstract

 

Antifungal activity of eucalyptus (Eucalyptus camaldulensis Dehnh.) essential oil was evaluated and suppressed the mycelial growth of postharvest pathogenic fungi, Penicillium digitatumAspergillus flavusColletotrichum gloeosporioides and soilborne pathogenic fungi, Pythium ultimumRhizoctonia solaniBipolaris sorokiniana pathogenic fungi. The experiment was carried out with Whatman paper disc method in 25, 50, 75 and 100% concentration of essential oil on PDA culture at 25°C and mycelial growth measured daily for 30 days. The antifungal activity was evaluated under a randomized completely factorial design with three replications. The result showed eucalyptus essential oil in all concentration had completely inhibition of mycelial growth only in P. ultimum and R. solani.

 

Key words: Antifungal activity, essential oil, eucalyptus.
