Non-chemical methods are never used in IPM.

• A. True
• B. False
• C. Not sure
• D. Sometimes

Answer: (B)

Integrated Pest Management relies on using a range of tactics, with non-chemical methods often taking the lead. Cultural practices (like crop rotation and sanitation), mechanical and physical controls (traps, barriers, hand-picking), and biological controls (natural enemies) all work together to reduce pest populations and lower the need for pesticides. Because of this approach, the idea that non-chemical methods are never used is not correct. They are routinely employed as part of IPM, and chemical controls are considered only when pest levels exceed a defined threshold or when non-chemical methods alone aren’t enough. The other options imply absolutes or uncertainty, whereas the best understanding is that non-chemical methods are a standard and integral part of IPM.
