CropDiseasePathogen
(1)CitrusCankerPseudomonas rubrilineans
(2)PotatoLate blightFusarium udum
(3)BrinjalRoot-knotMeloidogyne incognita
(4)Pigeon peaSeed gallPhytophthora infestans
  • Citrus — Canker — <em>Pseudomonas rubrilineans</em>
  • Potato — Late blight — <em>Fusarium udum</em>
  • Brinjal — Root-knot — <em>Meloidogyne incognita</em>✔️
  • Pigeon pea — Seed gall — <em>Phytophthora infestans</em>
Correct Answer Explanation
The correct match is Brinjal — Root-knot — Meloidogyne incognita. Meloidogyne is a nematode that causes root-knot disease in many vegetables including brinjal. Late blight of potato is caused by Phytophthora infestans, not Fusarium. Citrus canker is bacterial (Xanthomonas).
