• A. Chemical control
• B. Biological control
• C. Physical control
• D. Ecological control

Hint:

Chemical control uses substances such as insecticides and pesticides to manage pest populations quickly and effectively.

Answer 1

The Correct Option is A

Step 1: Understanding pest control methods.
Pest control refers to the methods used to reduce or eliminate harmful insects, pests, or organisms that may damage crops, spread diseases, or affect human health. These methods are broadly classified into chemical, biological, physical, and ecological controls.
Step 2: Meaning of chemical control.
Chemical control involves the use of chemical substances such as insecticides, pesticides, herbicides, and fungicides to eliminate harmful organisms. These chemicals directly affect pests and help control their population.
Step 3: Analysis of the given options.

• (A) Chemical control: Correct. Insecticides are chemical substances used to kill or control insects.
  
• (B) Biological control: This method involves using natural predators, parasites, or pathogens to control pests.
  
• (C) Physical control: Physical methods include traps, barriers, or manual removal of pests.
  
• (D) Ecological control: This involves altering environmental conditions to reduce pest populations.
  

Step 4: Conclusion.
Since insecticides are chemical substances used to eliminate insects, their application represents chemical control. Final Answer:} Chemical control.
