Leaf Rust (fungus - Puccinia recondita): Leaf rust occurs on either side of the leaf and on the leaf sheath as small, reddish-orange pustules (rust spores). In most years, leaf rust causes more damage in Texas than any other wheat disease. Growth is rapid between 59 - 72o F. It causes a reduction in the number and size of kernels. The disease reduces forage production in fields where it is utilized for grazing. New races of the rust fungus originate naturally and challenge wheat varieties. The leaf rust fungus of wheat does not attack oats or barley. Control with resistant varieties and foliar fungicide applications.
