Which of the following is not correctly matched

Options

A. Root knot disease - Meloidogyne javanica
B. Smut of bajra - Tolysporium penicillariae
C. Covered smut of barley - Ustilago nuda
D. Late blight of potato - Phytophthora infestans

Answer

C

Explanation

(c) Option 'c' is mismatched because the smuts in which sori are covered by the membranous covering or peridium are called covered smuts. These are caused by Ustilago hordei, in which the sorus or smut ball is covered by a peridium of host cells. Ustilago nuda is responsible for causing loose smut of barley.
