Understanding Why Rose Rosetting Disease Appears in Distinct Regions of a Shrub Rose Plan

Jennifer Gray • April 9, 2026

This webinar dives into the problem of rose rosette virus. Shrub roses consist of multiple canes attached to a root system and produce beautiful spring growth in the form of new flowering stems and branches. Experts will provide an overview of how rose rosette virus first attacks flowering growth and can move throughout the stem. At the same time rosette symptoms appear in mature distinct stems of a plant and may be absent from others. The research delves into understanding how the vascular system connects the flowering stems and above ground canes. The research is to understand how virus movement between adjacent stems and only appears to cause disease in a few but not all canes of the same plant. This research is important to explore potential management approaches to safeguard rose.

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.
