Iris yellow spot virus had been found this past week in a few plants in commercial onion fields in Malheur County, Canyon County, and Washington County. So far, no widespread outbreaks have occurred.
Maintaining good thrips management will help limit the spread and severity of the disease. Infective adult thrips spread the virus from plant to plant as well as within a plant. Infective immatures also can spread the virus within a plant.
In addition to thrips management, minimize stress on onion plants by making sure fields are maintained at an adequate but not excessive fertility level, and that the soil moisture is kept at about the 20 centibar level. This will help reduce the severity of virus symptoms.
