Unfortunately Spotted Lanternfly has spread in NYS this year and it will likely have a wider distribution in the 2022 growing season. Although it appears Spotted Lanternfly will only pose a serious threat to grape vines and vineyards, it may be noticed on other horticultural, and even field crops, especially the juvenile SLFs. So as an ag educator you may observe SLF and/or get questions from growers.
Early detection and reporting in new areas is still very important as eradication efforts by NYS Ag & Mkts in outlying locations can delay the spread. Please promptly report any SLF sightings to the reporting portal below and also email NYSIPM specialist Brian Eshenaur (bce1@cornell.edu)about your finding and/or other questions you may have. We want to increase awareness as it appears that the 2021 infestation found in the Binghamton area was actually noticed by residents a year or two prior to it being reported. Since growers may be more likely to encounter SLF than the average citizen you may want to consider adding a few slides about Spotted Lanternfly to your upcoming presentations. See link below for access to PowerPoint presentations you can draw from.
Just a reminder, this is the time of year to keep an eye out for egg masses and at any time of year new detections are most likely along transportation corridors, parking lots and near stands of Ailanthus trees.
