Which of the following is NOT a cultural control method?

• A. Soil Fertility
• B. Planting
• C. Chemical Pesticide Application
• D. Crop Rotation

Answer: (C)

Cultural control methods are practices that reduce pest pressure by changing the crop environment or farming system rather than by killing pests with chemicals. Managing soil fertility influences plant health and stress levels, which can affect pest attraction and damage. Planting decisions, such as when and how densely to plant, help crops escape or minimize pest problems. Crop rotation disrupts pest life cycles by not feeding pests on the same crop year after year, reducing their numbers over time.

Chemical pesticide application, on the other hand, uses chemical agents to kill or suppress pests and is not considered a cultural control. It’s a direct pest management tactic rather than a modification of the crop system or environment. Thus, the option that is not a cultural control method is the chemical pesticide application.
