Diseases of Lisianthus

Abstract

Lisianthus, Eustoma grandiflorum (Raf.) Shinn., is an important cut and potted flower that has been in increasing demand over the last three decades. Its profitability can be decreased by failure to maintain demanding propagation and production requirements and by numerous diseases. Particularly challenging lisianthus diseases are caused by Botrytis cinerea, Fusarium spp., and an ever increasing number of viruses, especially the tospoviruses. Management strategies for lisianthus diseases recently studied include chemical, biological, cultural, and physical control, host resistance, and their integration.
