No crop is free of diseases, and this is true for both commercial lily bulb and flower production and garden/park plantings.
Several threats are present that can influence lily growth, yield and ornamental value and the more we grow this crop the more we have to deal with diseases.
For a widely-planted crop like the lily, research is done all over the world in regard to disease and disease control.
In this paper a literature review is combined with up-to-date grower information.
The main diseases are: viruses, for example: lily symptomless virus (LSV), lily mottle virus (LMoV) and plantago asiatica mosaic virus (PlAMV); fungal diseases like Botrytis, Fusarium, Phytophtora, Pythium, Penicillium and Rhizoctonia solani; root rot caused by nematodes (Pratylenchus penetrans); insects like aphids and the lily leaf beetles (Lilioceris lilii) and mites (Rhizoglyphus robini). Several other diseases and disorders can occur during propagation, storage and growing of lily bulbs.
In this article the main diseases and disorders are discussed along with their control measures.
Known and new knowledge or control measures of diseases and disorders are described.
There is a trend toward control without the use of chemicals, e.g., optimisation of the hot water treatment, fostering soil life, stimulation of biodiversity in the field, and biological control.
But also control strategies have become more practical such as growing virus free stocks and using decision support systems.
