Match List-I with List-II

List-I (Disease)	List-II (Symptom)
(A) Downy mildew	(I) Dead areas on the stem bark of woody trees
(B) Blight	(II) Angular and elongated spots appearing on the veins on the lower surface of the leaf
(C) Canker	(III) Cottony growth on the host surface
(D) Anthracnose	(IV) Burnt appearance

Choose the correct answer from the options given below:

Correct option is D

A. Downy mildew → (III) Cottony growth on the host surface

Downy mildew is caused by oomycete pathogens such as Peronospora, Plasmopara, and Pseudoperonospora.
A key diagnostic symptom is the appearance of downy or cottony fungal growth on the surface of infected plant parts, usually on the lower surface of leaves. This growth consists of the pathogen’s sporangiophores and spores.

Therefore, Downy mildew → Cottony growth on host surface (III).

B. Blight → (IV) Burnt appearance

Blight is a plant disease characterized by rapid and extensive death of plant tissues, especially leaves, flowers, or young shoots. Infected parts often appear scorched or burnt, which is why the symptom is described as a burnt appearance.

Examples include late blight of potato and bacterial blight of rice.

Therefore, Blight → Burnt appearance (IV).

C. Canker → (I) Dead areas on the stem bark of woody trees

Canker diseases affect woody plants such as trees and shrubs. The infection causes localized dead and sunken lesions on stems, branches, or bark. These lesions may enlarge over time and can disrupt nutrient movement in the plant.

Therefore, Canker → Dead areas on the stem bark of woody trees (I).

D. Anthracnose → (II) Angular and elongated spots appearing on veins on the lower surface of the leaf

Anthracnose diseases are caused by fungi such as Colletotrichum species. They typically produce dark, irregular, angular, or elongated lesions on leaves, stems, fruits, or flowers. These spots often follow leaf veins, giving them an angular appearance.

Therefore, Anthracnose → Angular and elongated spots on veins of the leaf (II).
