Abstract:
Gray mold caused by Botrytis species is a destructive and economically important plant disease. Numerous plants in home landscapes, nurseries and greenhouses are affected under favorable environmental conditions. It can be a special problem for greenhouse growers because rising energy costs have forced many to lower temperatures and reduce ventilation, causing condensation of moisture on plants and setting up ideal conditions for disease infection and spread. 2 Because botrytis has a wide host range there are many greenhouse plants which can be affected. Included among greenhouse hosts are African violets, begonias, poinsettias, snapdragons, chrysanthemums, cyclamen, and cinerarias. Botrytis can cause propagation problems with many herbaceous plants, notably geranium, and is a spoilage organism of plants and plant products during storage and transit.
