Bean yellow disorder crinivirus: a new whitefly-transmitted virus of bean crops found in Spain
In October 2003, a new disease of beans (Phaseolus vulgaris) was observed in the Province of Almería, Spain. Affected plants showed interveinal mottling and leaf yellowing combined with stiffness or brittleness, and were all grown in glasshouses infested with Bemisia tabaci. Affected pods are curved and smaller, with a bright and shiny green colour which affect their commercial value. Plant growth is reduced, and up to 40-50% yield loss is reported. Studies revealed the presence of a new crinivirus, and the name Bean yellow disorder crinivirus was proposed. Recommended control methods are mainly based on the control of the insect vector, B. tabaci (e.g. insect-proof glasshouses, yellow sticky traps, chemical/biological control) and destruction of all infected plants.
