In 2023, we monitored and received reports of spotted lanternfly instar development and population levels and locations. Here is a summary from those reports.

On June 1, 2024, significant changes were made to the Maryland invasive plant law. Plants on the Maryland Prohibited Invasive Plant List may not be acquired or sold in-state after the regulations effective date. Existing stocks of prohibited plants have a phase-out period of 1 year for potted plants and 2 years for in-ground plants. Prohibited plants must not be in stock after the phase-out period ends.

Traditional methods of spray applications involve extensive PPE, water use and labor time. Drones can be used instead of actual employees in the field to reduce the risk of exposure, the need for extensive and uncomfortable PPE, and water use for dilution. We set out to look at the efficacy of drone spray applications against traditional methods, such as an airblast sprayer for the control of gymnosporangium rust on Amelanchier.
