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

Answer: (A)

Physical control methods are actions that reduce pests or disease without using chemical pesticides. Washing plants physically removes pests, eggs, and fungal spores from surfaces, lowering the pest pressure. Using physical barriers such as nets, row covers, or screens prevents insects or larger pests from reaching the plants. Pruning infected or diseased plant material removes sources of pathogens and improves air circulation, which helps reduce disease development and spread. Because these approaches physically remove or block pests or pathogens rather than killing them with chemicals, they are classic physical, non-chemical control options and fit well within integrated pest management. They’re most effective when used together with other practices, though they may not be enough on their own in heavy infestations or with systemic diseases.
