Presented by Brian Walsh
While we still have a lot to learn, this session covers the status, impacts and management of spotted lanternfly in North America, including the latest information on the distribution of Spotted Lanternfly (SLF), SLF host preferences, and impacts on ornamental plants. Brian Walsh, Penn State Extension Horticulture Educator based in Berks County, Pennsylvania, also discusses the latest SLF management research on insecticide trials and treatment recommendations. Watch and arm your team with the latest research information and strategies to protect against the invasive SLF.

CABI and USDA APHIS are collaborating on the biological control of the box tree moth using parasitoids from Asia. Several parasitoid species are currently under consideration for introduction into North America and Europe. One of these parasitoids arrived in Europe on its own and has begun controlling the moth on both planted trees and in wild boxwood stands. The webinar will describe the spread and impact of this adventive parasitoid in Europe and present efforts to assess the potential of this species and others as biological control agents in North America.

This session will introduce the HortCalculator, an online decision-support tool designed to help ornamental growers translate farm-level data into actionable financial insights. The tool generates clear analyses of profitability, breakeven points, and return on investment, giving growers confidence to evaluate sustainable production practices and new technologies. By linking financial literacy with production decisions, the HortCalculator helps growers balance profitability and sustainability, strengthening resilience in ornamental horticulture systems. The session will highlight practical applications for nursery, greenhouse, and specialty crop operations, while also exploring opportunities for research, education, and industry partnerships to scale the tool across crops and regions.
