Diario del proyecto NPSO PDX, Native Rhododendrons of Oregon

The Azalea Lace Bug is a pest on rhododendrons, especially in gardens. Some hybrids and species are more susceptible to infection by the pests than others. Try avoid growing plants that are susceptible to these pests. I don't know of a complete list of hybrids/species rhododendrons that are, or are not susceptible though. https://www.inaturalist.org/observations/188059606
