Antifungal activity of stone fruit aroma compounds against Monilinia laxa (Aderh. et Ruhl.) Honey and Rhizopus stolonifer (Ehrenb.): in vivo trials.

 

In vivo trials were carried out to assess the antifungal activity of vaporized benzaldehyde, benzyl-acetate, benzyl-alcohol, epsilon -caprolactone, gamma -decalactone, hexanal, methyl-salicylate and gamma -valerolactone from stone fruits. Peach, nectarine and plum fruits were wounded and inoculated with M. laxa or R. stolonifer then treated with vapours for 24 h. Benzaldehyde at 5000-10 000 p.p.m. had a significant fungistatic effect on M. laxa. The fungistatic activity proved total for 48 h at 20 deg C. Benzaldehyde activity against R. stolonifer was weaker. At 2500 p.p.m., hexanal produced the same fungistatic effect as 5000-10 000 p.p.m. benzaldehyde, but at higher concn became phytotoxic. Methyl-salicylate showed some fungistatic activity, but the particularly unpleasant odour transmitted to the fruit makes further experimentation unfeasible.
