Question

Match List I with List II:
List I:
A. Cold storage
B. Shaking the plants
C. Use of pheromone trap
D. Destruction of crop residue
List II:
I. Cultural control
II. Mechanical control
III. Physical control
IV. Behavioural control
Choose the correct answer from the options given below:

• A. A-III, B-II, C-IV, D-I
• B. A-II, B-I, C-IV, D-III
• C. A-III, B-IV, C-I, D-II
• D. A-I, B-II, C-III, D-IV

Hint:

To differentiate:
- Physical: Modifies heat, light, humidity (e.g., cold storage).
- Mechanical: Uses manual force or devices (e.g., handpicking, shaking plants).
- Cultural: Normal farming manipulations (e.g., crop rotation, tillage, sanitation).

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Integrated Pest Management (IPM) incorporates multiple tactics (cultural, physical, mechanical, chemical, and biological) to suppress pest populations.

Step 2: Detailed Explanation:
Let us match the agricultural pest management practices with their correct control classifications:
A. Cold storage: Modifies temperature (an environmental physical parameter) to prevent grain spoilage, falling under Physical control (III).
B. Shaking the plants: Employs manual force or hand-labor to dislodge insect larvae (like defoliators), falling under Mechanical control (II).
C. Use of pheromone trap: Employs chemical attractants to manipulate or disrupt insect mating behavior, falling under Behavioural control (IV).
D. Destruction of crop residue: Involves agronomic sanitation practices to remove shelter/overwintering sites of pests, falling under Cultural control (I).
Therefore, the correct match is:
A-III, B-II, C-IV, D-I

Step 3: Final Answer:
This matching sequence is represented by option (A).
