Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of disease transmission by insect vectors.
Step 2: Detailed Explanation:
Fungal wilt of date palm (D) is transmitted by beetles.
It is caused by the fungus Ceratocystis paradoxa.
The disease is also known as "Bayoud disease" in some regions.
Beetles act as vectors, carrying the fungal spores from infected to healthy trees.
Other wilt diseases:
- Bacterial wilt of tomato (A): Caused by Ralstonia solanacearum (soil-borne, not beetle-transmitted).
- Fungal wilt of banana (B): Caused by Fusarium oxysporum f. sp. cubense (soil-borne).
- Bacterial wilt of banana (C): Caused by Ralstonia solanacearum (soil-borne).
Thus, fungal wilt of date palm is transmitted by beetles.
Step 3: Final Answer:
Thus, fungal wilt of date palm is transmitted by beetles, which corresponds to option (D).
