Question 1 of 5
1. Question
With reference to the Dieback Disease, recently in the news, consider the following statements:
- It is a fungal disease belonging to the genus Phytophthora that kills a wide variety of plants.
- It spreads through the movement of soil and mud, free water, and root-to-root contact between plants.
- Currently, there is a proven cure available for the disease involving the application of bio-agents like Trichoderma.
Which of the statements given above is/are correct?
Correct
Q.1) Solution (a)
Explanation:
- Statement 1: Correct – Dieback disease is a fungal disease caused by the genus Phytophthora. It affects and kills a wide variety of plants, including neem trees.
- Statement 2: Correct – The fungus spreads through the movement of soil and mud (especially via vehicles and footwear), in free water, and through root-to-root contact between plants.
- Statement 3: Incorrect – Currently, there is no known cure for dieback disease. Trichoderma is a bio-agent used for biological control (prevention through seed treatment), not a cure. The statement incorrectly claims a cure exists.
Thus, statements 1 and 2 are correct.
Why this question?
Tests the causative agent, transmission modes, and the distinction between prevention (biological control) and cure.Why important for UPSC?
