First report of Verticillium dahliae causing wilt in pumpkin in Trinidad
Plant Disease 92 (7), 1136-1136
Abstract: During 2006 and 2007, pumpkin (Cucurbita pepo) plants grown in Trinidad were observed with symptoms of yellowing with subsequent browning of the older leaves and stems followed by wilting, girdling, and dieback of vines. Yield losses were estimated at 30 to 80%. The fungus Verticillium dahliae was isolated from the diseased plants. The identification was based on morphological characteristics and ITS sequence analysis. Pathogenicity of the isolates was demonstrated by inoculation and re-isolation.
