Situation Update Feb 2010
Ethiopia: Results of the field surveys undertaken in Sep-Dec 2009 were received. Very comprehensive surveys were undertaken covering virtually all the main wheat growing areas. A total of 877 locations were surveyed. Thirty-five percent of the locations were infected by stem rust. Highest incidence of stem rust occurred in the southern areas, notably the Arsi/Bale region, and the disease was widespread in the Rift Valley area south of Addis. Stem rust was infrequent in northern and western areas. No information on races present is currently available.
Kenya: Field surveys were undertaken in the Mount Kenya and Central Rift Valley regions in Jan-Feb 2010. A total of 90 locations were surveyed. Fifty-nine percent of the locations were infected with stem rust and the disease was widespread throughout the regions surveyed. Approximately 77% of the locations surveyed had been sprayed with fungicides. Confirmation of races present is not yet available.
Yemen: Moderate to high incidence of stem rust was recorded in the screening nursery at Al Kedan on the Red Sea coast in the first week of Feb 2010. Samples are under going race analysis.
