First report of sugar beet crown wart disease caused by Urophlyctis leproides in Egypt
Plant Pathology 56 (2), 356-356
Abstract: Leaf and crown wart of sugar beet (Beta vulgaris ) caused by Urophlyctis leproides (Physoderma leproides) was observed in Egypt during harvest (2003, 2004, 2005) at three locations in the Nile Delta. Affected leaves were malformed and galls ranged in size from 1 cm to (most commonly) 8-10 cm. Sections made through a crown gall reveal cavities filled with thick-walled sporangia (resting spores) surrounded by thickened wall. Sporangia were light brown, spherical to ovoid or concave (25 ±5 - 40 ±5 µm) in diameter. Pathogenicity of the spores was confirmed by inoculation and re-isolation.
