Foliar plant pathogens are pigmented in nature and cause crop losses in major staple crops in the world as:
A. Pigments help them to tolerate high radiation
B. They cause diseases only on monocots
C. They cause diseases only on dicots
D. They move from one plant to another plant with the help of wind
E. They cause polycyclic diseases
Choose the correct answer from the options given below:
A. Pigments help them to tolerate high radiation
B. They cause diseases only on monocots
C. They cause diseases only on dicots
D. They move from one plant to another plant with the help of wind
E. They cause polycyclic diseases
Choose the correct answer from the options given below:
Show Hint
- Pigmented (UV protection).
- Spread by wind.
- Cause polycyclic diseases.
- Affect both monocots and dicots.
- A, B, C Only
- B, C, D Only
- C, D, E Only
- A, D, E Only
The Correct Option is D
Solution and Explanation
This question tests knowledge of foliar plant pathogens and their characteristics.
Step 2: Detailed Explanation:
A. Pigments help them to tolerate high radiation: Correct.
Pigments (melanin, carotenoids) protect foliar pathogens from UV radiation.
B. They cause diseases only on monocots: Incorrect.
Foliar pathogens affect both monocots and dicots.
C. They cause diseases only on dicots: Incorrect.
Foliar pathogens affect both monocots and dicots.
D. They move from one plant to another plant with the help of wind: Correct.
Wind dispersal of spores is common for foliar pathogens.
E. They cause polycyclic diseases: Correct.
Foliar pathogens have multiple infection cycles per season.
Thus, A, D, and E are correct.
Step 3: Final Answer:
Thus, the correct answer is A, D, E Only, which corresponds to option (D).
