This particular fungus may cause many problems in horticulture. It is essentially a fungus that survives in the compost and infects and destroys plant material where the humidity is too high and the conditions too warm. In plant propagation the disease normally affects cuttings inserted in mist propagators, closed cases or in pots under polythene bags. It causes basal rot of the cuttings, and it is by no means easy to control once it has established itself in the propagating area.
To prevent initial establishment of rhizoctonia, once or twice a year sterilize the propagating area. Always use equipment and containers that have been thoroughly cleaned when propagating and ensure the compost is fresh and sterile.
If the infection does appear, pick out and destroy the diseased plants.
