Impatiens Necrotic Spot Virus (INSV) was detected on lettuce in the desert in spring of 2021. This disease did not have a significant impact in most fields, but the impact of this disease in subsequent seasons cannot yet be predicted. To prepare for the next lettuce season, a workshop has been planned to provide information on what is known about this disease including the biology of the virus and vector, host range and virus & vector control.

This workshop, co-hosted by the University of Arizona's Yuma Center of Excellence for Desert Agriculture and Yuma County Cooperative Extension and the University of California Riverside, will be held virtually (Zoom link to be provided after completing registration) and in-person (at the Yuma Agricultural Center) from 8-11 AM on August 11, 2021. In-person attendance will be limited to 60. Register early to secure an in-person seat.
