Biology and control of Xanthomonas hyacinthi in hyacinths


, : Biology and control of Xanthomonas hyacinthi in hyacinths. Acta Horticulturae (47): 99-105

In hyacinth yellows disease, caused by X. hyacinthi, the bacteria present in the bulb at planting can spread from the bulb into the leaves, and from early spring onward the disease can be dispersed in the field by rain and wind. In addition, machines used for lifting and sorting of bulbs and the knives used for bulb scooping and scoring (in propagation) can spread the bacteria from diseased to healthy bulbs.

The fimA gene was amplified by PCR with degenera...
