Q.1
Vegetable Science- ICAR JRF/SRF 2024 (Q.51)
MCQ (Single Correct)
The causal organism of Inflorescence blight disease of marigold is.
EXPLANATION Marigold and Jasmine Production Technology
  • Inflorescence Blight in Marigold (Tagetes spp.):
  • devastating floral disease caused by the fungal pathogen Alternaria zinniae (along with Alternaria tagetica).
  • Induces circular brown to black necrotic spots on ray florets, pedicels, and involucral bracts, which rapidly coalesce under humid conditions to cause complete blighting and rotting of flower heads.
  • Correct Option: Option 2 (Alternaria zinnae).
