What factor has contributed to reducing chemical use on golf courses?

• A. Conventional pesticide rotation
• B. Integrated pest management programs
• C. Increased fertilizer use
• D. Routine broad-spectrum spraying

Answer: (B)

Integrated pest management programs reduce chemical use by combining careful monitoring with selective, targeted controls. Regular scouting helps identify pests accurately and determine whether action is truly needed, using action thresholds or economic injury levels. When action is required, turf managers rely on a mix of cultural practices (like proper mowing, irrigation, and soil health to keep turf strong), biological controls, and, if necessary, the least toxic or most targeted pesticides rather than blanket, routine spraying. This focused approach minimizes unnecessary applications, protects beneficial organisms, and often lowers overall chemical inputs. Conventional pesticide rotation can help manage resistance but doesn’t by itself guarantee fewer sprays. Increased fertilizer use isn’t aimed at reducing chemicals, and routine broad-spectrum spraying tends to increase chemical usage.
