Lowering humidity in stored grains to reduce mold damage is an example of which pest management approach?

• A. Chemical control
• B. Cultural/environmental control
• C. Biological control
• D. Regulatory control

Answer: (B)

Changing storage conditions to prevent pests is a cultural/environmental control approach. Lowering humidity in stored grains reduces mold damage by limiting the moisture available for fungal growth, which makes the environment less favorable for pests. This relies on storage practices like drying grain to a safe moisture content, proper aeration and ventilation, and keeping bins clean and monitored, rather than applying pesticides, introducing living organisms, or enforcing regulations.
