Leaf Rust /Brown Rust: Puccinia recondita

Symptom:

• The postules are circular or slightly elliptical, smaller than those of stem rust, usually do not coalesce, and contain masses of orange to orange-brown Urediospores
• Infection sites primarily are found on the upper surfaces of leaves and leaf sheaths and occasionally on the neck and awns
• Survival : Both survive on stubbles and volunteer crops
• Alternate host : Thalictrum sp.
• Spread : uredospores from hills
