Announcements
The Long Island Arborcultural Assosciation held our annual Arbor
Day at
Vanderbilt Museum and Planetarium
Despite the rain and wind we still made a big impact.
Together our members donated their time to remove hazardous trees. It’s work that would exceed $80k, and was greatly appreciated by the museum.
Please enjoy these photos of their hard work!

Safety Talk Hosted by Husqvarna
Members also brought their own equiptment to get the job done!
Every year the LIAA donates a tree to our hosts!
Laurel Wilt found on Long Island, first time in New York
Hello all,
Margery Daughtrey of the Cornell University-Long Island Horticulture Research and Extension Center (LIHREC) recently identified the pathogen that causes laurel wilt on a wilting sassafras at a home in Northport, Long Island, New York. She sent the sample to the University of Florida, Tropical Research and Extension Center (TREC) for molecular identification and confirmation was concluded at the USDA-APHIS-PPQ-NIS Molecular Laboratory in Beltsville, Maryland. The insect vector, the redbay ambrosia beetle (Xyleborus glabratus), is also an introduced species and it was also recently found in Long Island and it’s ID confirmed.
Please consider joining us on September 10th for an informative webinar about laurel wilt.
Please post-hang-share the two attachments, a save the date poster and an agenda poster.
Cornell University Plant Pathologists are hosting this event to share information about this new plant disease of sassafras and spicebush and the insect vector that can spread it from tree to tree. Several experts from southern states with experience with the laurel wilt disease and vector will share their observations and what they have learned. The webinar topics include the discovery on Long Island, the history and impacts of laurel wilt in the US, sassafras and spicebush as hosts, understanding the beetle vector, the disease diagnostic methods, how to report suspect trees, and how to submit samples for a disease diagnosis.
If this interests you, please mark your calendars!
