Who made the 1st report of nematode associated with plant disease in 1943?

Answer: Option C

Needham made the 1^st report of nematode associated with plant disease in 1943.
Turbevil Needham accidentally recorded the first plant parasitic nematode when he crushed one of the shrunken and blackened wheat grains and observed “Aquatic worms, Eels, or Serpents, which they very much resemble.” He named it Vibrio tritici. Later this nematode was rightly named Anguina tritici by Steinbuch.
From 1750 to the early 1900s, Nematology research continued to be descriptive and taxonomic, focusing primarily on free-living nematodes, and plant and animal parasites.
