May 1, 2011: Egypt rust survey summary – Leaf rust predominates, traces of yellow rust, but stem rust absent

Wheat rust surveys were undertaken during the period mid February to the end of April 2011. The surveys covered the wheat growing areas of the Nile Valley from Aswan to the Delta. A total of 32 wheat fields were surveyed using standard BGRI survey methodology. Stem rust was absent in all the fields surveyed. Leaf rust was widespread and the predominant rust recorded on the survey. Leaf rust was observed in 90% of the fields visited, but mainly the disease was at low severity. Only 4 fields (all in the Delta) were observed to have high disease severity (>40%). Yellow rust was only observed in trace amounts. Only 2 fields were recorded with the disease, one of which had high severity.
