Which practice is described as using modifications to the environment or pest life cycle to reduce pest pressure?

• A. Biological control
• B. Cultural control
• C. Chemical control
• D. Mechanical control

Answer: (B)

Using modifications to the environment or pest life cycle to reduce pest pressure is cultural control. This approach changes the crop setting or timing so pests have fewer opportunities to survive, reproduce, or damage crops without applying pesticides. Examples include rotating crops to break pest-host cycles, altering planting dates or densities to avoid peak pest activity, and cleaning fields to remove debris or alternative hosts that harbor pests. By making the environment less favorable or misaligning pest life cycles with the crop, you lower pest pressure in a sustainable, non-chemical way. This differs from biological control, which relies on natural enemies to suppress pests; chemical control, which uses pesticides; and mechanical control, which involves physical removal or barriers.
