Stem / Black Rust of Wheat
• World wide
• Epidemic in the world & India
• March – April in north India
• Nov. – Dec. in South India
• Below - 3000 feet
• Loss – 90%
Symptoms :
• Affect all parts except roots
• Brown color pustules
• Bursting of epidermis by urediospore
• Later stage – teliospore formation
• Due to teliospore / urediospore black appearance- called
black rust
Effect on pls.
• Early ripening
Black rust of wheat
• No grain formation or small in size
• Low quality flour
• Pl. – small in size
• Less tillering
• Loss of shining of seed & pls.
• Low quality straw not eaten by animals
• ↓ photosynthesis
• ↑Transpiration & respiration
Black rust of wheat
Pathogen – Puccinia graminis f. sp. tritici
• Spores – 1. Pycniospore - Pycnidial stage - O
2. Aceospore – Aecial stage – I
3. Urediospore – Uredial stage – II
4. Teliospore - Telial stage – III
5. Basidiospore – Basidial stage - IV
Systemic Position
Kingdom – Mycota/ Fungi
Division – Eumycota
Sub division – Basidiomycotina
Class – Teliomycetes
Order – Uredinales
Family – Puccinaiaceae
Genus – Puccinia
Species - graminis f. sp. tritici
Disease Cycle
• Hetrocious - different host – Berberis,
Mohinia
• Macro cyclic – all 5 stages
• Fav. Conditions-
• Tem 17-18 º C for rapid spread
• 15.5-21º C for Urediospre germination

Disease Management
• Early sowing
• Mixed cropping
• Balance fertilizer –↓ N ↑ K
• Proper irrigation
• Dithane M- 45@ 2-3 kg/ha or Tilt @ 0.1% or Plantavax@.02%
IInd spray 10 days after Ist spray & IIIrd spray at 14 days
