Yemen: Wheat rust surveys undertaken by AREA, Yemen in the key wheat growing areas of the country during October 2010 to March 2011 revealed stem rust to be widespread in the highlands and western areas, but absent in the eastern regions around Seiyun. Of the 33 fields surveyed in the highlands and west of the country in October 2010, stem rust was recorded in 27 (82%) of the fields. Disease severity was high to moderate (>20%) in 13 fields. In contrast stem rust was completely absent from the eastern regions around Seiyun in surveys undertaken in Feb-Mar 2011. Stem rust races present in Yemen during 2010/11 are currently unknown, but samples are undergoing analysis.
