Typical symptoms on leaves occurs during the wheat jointing to heading growth stages. Typical symptoms include chlorotic, interveinal stripes that extend the length of the leaf blade, or brown stripes bordered by yellow stripes. The veins within stripes are dark brown.
Plants generally die prematurely and produce little grain.
Leaf symptoms can be recognized in early spring before jointing, but the typical stripes are not easily detected until jointing. Evidence of the brown veins can be detected in prematurely killed plants.
