In what way can physical barriers assist in pest control?

• A. They beautify the garden
• B. They prevent pests from accessing crops
• C. They replace the need for any pesticides
• D. They improve soil quality

Answer: (B)

Physical barriers are an effective method of pest control because they physically obstruct pests from reaching and damaging crops. This technique includes the use of nets, fences, row covers, and other structures designed to keep pests away from vulnerable plants. By creating a tangible barrier, these methods can significantly reduce the incidence of pest damage without the use of chemicals, thereby promoting healthier crops and reducing the reliance on pesticides.

While beautifying the garden, improving soil quality, or eliminating the need for pesticides are valuable aspects of gardening and pest management, they do not directly address how physical barriers function specifically in pest control.
