A New Report for Downy Mildew [(Hyaloperonospora camelinae Gäum.) Göker, Voglmayr, Riethm., M. Weiss & Oberw. 2003] of Camelina [Camelina sativa (L.) Crantz] in the High Plains of the United States – Harveson, R. M., Santra, D. K., Putnam, M. L., Curtis,
Summary: Camelina was recently introduced into North America, where it is currently grown commercially in Montana and North Dakota. During early June 2010, camelina plants from cultivar research trials began exhibiting downy mildew-like symptoms consisting of upper stem distortion and signs of white, fluffy masses covering stems, seed pods and heads. More investigation is warranted to determine whether these observations are due to plant genotypes or some other factor. Downy mildew has the potential to be a major yield-limiting factor on camelina production in the USA High Plains.
