Impatients Necrotic Spot Virus on desert lettuce topic of hybrid workshop

Impatients Necrotic Spot Virus was detected in spring 2021 on lettuce in the Western desert of the U.S.

Although the disease did not have a significant impact in most fields, the impact of Impatients Necrotic Spot Virus (INSV) in subsequent seasons cannot yet be predicted.

To help growers prepare for the upcoming lettuce season, a hybrid workshop will be held on Aug. 11 to provide information on what is known about this disease, including the biology of the virus and vector, host range and virus and vector control.

Sponsored by the Yuma Center of Excellence for Desert Agriculture, University of California, Riverside and University of Arizona Cooperative Extension, the Desert INSV Workshop will be held from 8-11 a.m. (MST).

It will be held virtually (Zoom link to be provided after completing registration) and in-person (at the Yuma Agricultural Center, 6425 W. 8th St). In-person attendance will be limited to 40. Register early to secure an in-person seat.

Arizona and California CEUs are pending.
