May 30, 2010: Algeria rust survey summary – Yellow rust and leaf rust widespread, but stem rust absent

Wheat rust surveys were undertaken in May 2010 throughout the north-eastern wheat growing areas. A total of 103 wheat fields were surveyed using standard BGRI survey methodology. Forty-four percent of the fields surveyed were Durum Wheat, 30% Bread Wheat and 26% Barley. Stem rust was absent in all the fields surveyed. Yellow rust was the most widespread rust recorded on the survey, present in 65% of the fields visited with moderate or high disease severity (>20%) recorded in 40 of the fields. Leaf rust was also widely distributed, recorded in 56% of the fields visited – although moderate or high disease severity was only recorded in 16 fields.
