Volatile plant metabolites for postharvest crop protection.

The plant volatiles S-carvone, carvacrol and decanal were evaluated for their potential to suppress conidial germination and mycelial development of Penicillium hirsutum, the causal agent of storage rot of flower bulbs. A new in vitro assay was developed to quantify the fungicidal activity of such volatiles on conidia. S-carvone, carvacrol and decanal inhibited conidial germination of P. hirsutum at very different rates, decimal reduction times varying from 1 day with S-carvone to 1 hour with decanal. S-carvone and carvacrol also acted fungicidally on the mycelium. In in situ experiments, only S-carvone completely suppressed development of Penicillium on Dutch Iris bulbs (cvs. Blue Magic and Prof. Blaauw).
