Which pest management method involves destroying diseased plant material?

• A. Exclusion
• B. Sanitation
• C. Host resistance
• D. Habitat modification

Answer: (B)

Sanitation in pest management focuses on removing and destroying diseased plant material to cut off sources of disease. By clearing and disposing of infected debris and plant parts, you reduce the amount of pathogen present in the field and prevent it from spreading to healthy plants. This interruption of the disease cycle helps protect upcoming crops and lowers future losses.

Exclusion is about keeping pests from entering the growing area, not specifically about diseased material. Host resistance relies on using plant varieties bred to resist pests or diseases rather than removing infected material. Habitat modification changes the environment to make it less favorable for pests, rather than directly eliminating diseased plant debris.
