Pest management is an important aspect of agriculture, shade tree maintenance, and forest health. Correctly timing activities, such as pesticide applications or scouting for specific insect pests, can be challenging because of variation in the weather from one year to the next and from one part of the state to another. The growing degree day (GDD) resources below are available to help you improve your insect management activities in New Hampshire.
