During cultivation of pot plants, the growth of a gilled mushroom called flowerpot parasol (Leucocoprinus birnbaumii) can be a problem. Also other species of Leucocoprinus are occasionally found during cultivation in greenhouses. Hygiene is important to prevent the spread via soil and water.
This year, a research project is performed by Wageningen UR Greenhouse Horticulture, to develop methods to control the growth of this mushroom. This research is funded by the Dutch Horticultural Board (Productschap Tuinbouw).
Laboratory tests showed that the sugar content of the substrate influences the growth of Leucocoprinus, whereas preventative application of oxidative and biological products may reduce the growth of this mushroom.
This summer, we will perform an experiment in our greenhouses in which we will monitor the effect of these biological products on the growth of Leucocoprinus during cultivation of Kalanchoë en Aloë Vera. Moreover we will study the potential role of plant defense reactions in controlling Leucocoprinus growth.
A flyer with information on the life cycle of Leucocoprinus and the results of recent studies on control and prevention is available on the website of Wageningen UR and LTO Glaskracht.
