Abstract

Faba bean (Vicia faba) plants showed symptoms of shoe stringed leaves, phyllody and flower abortion in experimental field. The first symptoms consisted of phyllody mild yellowing, vein clearing and slightly inward folding of newly formed leaves in the apical region of the plant. The disease was characterized by a series of floral abnormalities including virescence, phyllody and proliferation of sprouts together with other abnormalities, such as loss of apical dominance, vivipary and enhanced vegetative growth. Ambient temperature found to be contributing positively on disease development. Under climate change condition there may be every possible chance for speedy spread of this very economic important disease to the earlier not known regions.
