Assertion (A): Biological control developed for treatment of plant diseases.
Reason (R): Trichoderma are free living fungi common in root ecosystem.
Reason (R): Trichoderma are free living fungi common in root ecosystem.
Show Hint
- A and R are correct. R is the correct explanation of A.
- A and R are correct. R is not the correct explanation of A.
- A is correct but R is incorrect.
- A is incorrect but R is correct.
The Correct Option is A
Solution and Explanation
Biological Control in Plant Disease Management
Assertion (A): Biological control is a method developed to treat plant diseases by using natural organisms or substances to control pests or pathogens. Trichoderma, a genus of fungi, serves as an example of such biological control agents. (✔ Correct)
Reason (R): Trichoderma are free-living fungi commonly found in the root ecosystem of plants. They act as biocontrol agents by competing with harmful pathogens and promoting plant growth. (✔ Correct)
Since both statements are correct, and the reason correctly explains the assertion, the correct answer is:
(A)
