5. Rust of Wheat Three species of Puccinia causing rust 2 Pathogen : Biotrophic , Obligately parasitic, Basidiospores not contained within Basidiocarp, macrocyclic (5 possible spore types), heteroecious The three species of Puccinia causing rust: Stem rust or black rust ( Puccinia graminis) Leaf or brown rust ( Puccinia recondite ) Stripe or yellow rust ( Puccinia striiformis )

6. Rust of Wheat Stem Rust 2 Stem rust (Puccinia graminis ) is a destructive fungal disease of wheat, marked by reddish-brown pustules on the stems

7. Rust of Wheat Leaf or Brown Rust 2 Leaf rust, caused by (Puccinia recondita ) , is a common fungal disease affecting wheat crops, characterized by brown rust pustules on the leaves.

8. Rust of Wheat Stripe or Yellow Rust 2 Stripe rust, caused by (Puccinia striiformis ) , is a fungal disease impacting wheat crops, manifesting as yellow rust stripes on the leaves.

10. Smut of Wheat 3 Two species of Ustilago causing smut Disease of hills and terai, internally seed borne Causal agent: Ustilago nuda The teliospores are single celled and formed irregularly from fertile hyphae. T eliospo r es are o l ivace o us brow n , s phe r ical to oval , m eas u res 5 - 9μm in diameter The two species of Ustilago causing smut : Loose smu t ( Ustilago nuda ) Flag smu t ( Urocystis agropyri )

11. Smut of Wheat 3 Loose smut of wheat Loose smut of wheat, caused by the fungus Ustilago tritici , is a significant disease affecting wheat crops. The fungus replaces wheat grains with dark smut spores, leading to yield losses and reduced grain quality

12. Smut of Wheat 3 Flag smut of wheat Flag smut of wheat, caused by the fungus Urocystis agropyri , is a disease that affects wheat plants, particularly during the flag leaf stage. It manifests as black streaks on the leaves and can lead to yield losses
