This season, we’ve observed some expansion of the BTM hot spots. Whether this is due to natural spread, or the discovery of undetected infestations is not known. However, owing to BTM’s multiple generations, damage is rapidly ramping up to produce some dramatic impacts and questions about BTM management.

The “tHRIve - WEB SERIES” is where you can remain updated on a wide range of issues important to the Green Industry.  The webinar titled, “Box Tree Moth Demystified” was presented live last Wednesday, May 15.  The webinar covers what to look for with BTM and the latest results from BTM management trials.
