·
Correct:
D
Explanation
The correct matching of plant diseases with their causal factors is as follows:
- Citrus Canker: It is a bacterial disease caused by Xanthomonas axonopodis pv. citri, which affects the leaves, stems, and fruit of citrus trees.
- Red rot of sugar cane: This is a major fungal disease caused by Colletotrichum falcatum, leading to significant yield loss.
- Krishnakant (Black Heart) of potato: This is a physiological disorder caused by a deficiency of oxygen in the internal tissues of the potato, usually due to poor ventilation during storage or transport.
- Sahu (Sehu) disease of wheat: Also known as Ear Cockle, it is caused by the nematode Anguina tritici. In general science classifications, it is often grouped under pests or insects.
Matching these gives the sequence: A-3, B-4, C-2, D-1.
