Integrated pest management strategies can significantly improve the health of afflicted trees, including the use of systemic root flare injections to manage beech leaf disease.
That perspective has become especially important as emerging pests and dis- eases spread across North America. Recent advances in pesticide technolo- gy are offering new hope — particularly in the battle against BLD. Experts from around the country are testing these tools, comparing notes, and sharing
what is showing early promise in their own landscapes and plant healthcare programs. Brewer is among those reporting en- couraging results.
Other techniques include:
•Installing barriers or traps, selec- tively pruning dead, damaged, or diseased material, •Releasing applicable biocontrols, •Applying targeted pesticides, •Choosing appropriate tree species, and •Cultivating a desirable growing environment for trees. Even though chemical controls have declined in recent years, they still serve an important purpose within an IPM program. As Borden explained, “While we can- not rely solely on chemical tools, diver- sifying modes of action is important to reduce the risk of resistance develop- ment.” His point underscores why PHC profes- sionals continue exploring new chem- istries and application methods rather than abandoning them altogether.

Keeping a close eye on early signs and symptoms is key to stopping problems before they spread, both by correctly identifying the culprit and applying treatments at the right stage of its life cycle.
