Which statement best describes a preventative pesticide application?

• A. Made after the problem is noticed
• B. Made during pest migration
• C. Made when turf is dormant
• D. Made before the problem appears

Answer: (D)

Preventative pesticide application is about treating turf before pests or diseases are visible, using knowledge of pest life cycles and seasonal risk to stop establishment and minimize damage. This proactive timing targets vulnerable stages—like egg hatch or early larval periods—and aligns with environmental conditions that make control most effective. Applying after signs appear is reactive and often too late to protect the turf; applying during migration tends to miss the main pest population and the resulting damage. While some treatments may be used during dormancy for certain diseases, the defining idea here is that the product is applied before the problem appears to prevent it.
