Which would be considered a preventive pest management strategy?

Choosing to plant weed- and disease-free seeds on an athletic field embodies a preventive pest management strategy because it proactively addresses potential pest problems before they arise. By starting with healthy seeds, the likelihood of weeds and diseases establishing themselves is significantly reduced. This method aligns with the principles of integrated pest management, emphasizing prevention and leveraging cultural practices to minimize pest impacts.

In contrast, relying on chemical pesticides regularly is a reactive approach that addresses existing pest problems rather than preventing them. Ignoring pest sightings does not provide any management and can lead to increased infestations over time. Similarly, applying pesticides during high pest seasons tackles problems after they have occurred, rather than employing methods aimed at prevention. Therefore, planting weed- and disease-free seeds is clearly the most aligned with preventive pest management strategies.
