NEET Biology QUESTION #7277
Question 1
Which one is the wrong pairing for the disease and its causal organism?
  • Root-knot of vegetables — <em>Meloidogyne</em> sp.
  • Late blight of potato — <em>Alternaria solani</em>✔️
  • Black rust of wheat — <em>Puccinia graminis</em>
  • Loose smut of wheat — <em>Ustilago nuda</em>
Correct Answer Explanation
The wrongly matched pair is Late blight of potato — Alternaria solani. Late blight of potato is caused by Phytophthora infestans (an oomycete), not Alternaria solani. Alternaria solani causes early blight of potato. The other pairings are correct: Meloidogyne causes root-knot, Puccinia graminis causes black rust, Ustilago nuda causes loose smut.
