Which of the following is NOT an effective cultural management practice?

• A. Tillage
• B. Crop rotation
• C. Insect/vector management
• D. Quarantines

Answer: (D)

Cultural management practices are actions you take on the farm to reduce pest pressure without relying on chemical controls. Quarantines are regulatory measures that restrict the movement of plant material, soil, or equipment to prevent the spread of pests between regions. They don’t involve on-farm steps you perform in the field, so they aren’t considered a cultural management practice. The other options describe on-farm actions: tillage disrupts pest life in the soil, crop rotation breaks pest cycles by changing hosts, and insect/vector management includes farm practices aimed at reducing pests such as sanitation and habitat modification.
