Abstract

Dry bubble disease caused by Lecanicillium fungicola is a persistent problem in the cultivation of the white button mushroom (Agaricus bisporus). Because control is hampered by chemicals becoming less effective, new ways to control dry bubble disease are urgently required. 1-Octen-3-ol is a volatile that is produced by A. bisporus and many other fungi. In A. bisporus, it has been implicated in self-inhibition of fruiting body formation while it was shown to inhibit spore germination in ascomycetes. Here, we show that 1-octen-3-ol inhibits germination of L. fungicola and that enhanced levels of 1-octen-3-ol can effectively control the malady. In addition, application of 1-octen-3-ol stimulates growth of bacterial populations in the casing and of Pseudomonas spp. specifically. Pseudomonas spp. and other bacteria have been demonstrated to play part in both the onset of mushroom formation in A. bisporus, as well as the inhibition of L. fungicola spore germination. A potential role of 1-octen-3-ol in the ecology of L. fungicola is discussed.
