Which of the following is a cultural control method?

• A. Rotating crops
• B. Using traps and barriers
• C. Releasing natural enemies
• D. Chemical pesticides

Answer: (C)

The main idea here is how pest control methods are categorized by what they change or use in the environment. Cultural control involves practices that alter the growing environment or farming routine to make it harder for pests to survive, reproduce, or reach their host. A classic example is rotating crops, which disrupts pest life cycles by breaking the continuity of the host plant available to them from season to season.

Releasing natural enemies, on the other hand, falls into biological control. This strategy relies on introducing or encouraging living organisms, such as predators, parasitoids, or pathogens, to reduce pest populations. It’s not about changing the crop system itself, but about using another living creature to keep pests in check.

Traps and barriers are physical or mechanical methods, designed to prevent pests from reaching the crop. Chemical pesticides are chemical controls, aimed at killing or repelling pests with chemical agents.

So, the cultural control method among these would be rotating crops, because it changes the agricultural system to reduce pest pressure. Releasing natural enemies is a biological control strategy.
