Dossier – Rose Downy Mildew

Rose Downy Mildew Symptoms

Roses are impacted by many diseases and insects. While rose downy mildew caused by Peronospora sparsa used to be considered of sporadic importance, it is now being seen more frequently during rose production by growers and in landscape installations.

As part of grant funding from USDA-NIFA SCRI, a team of researchers compiled known information on rose downy mildew, factors affecting its appearance and ways to mitigate its damage. The result is a dossier covering plant and fungal biology, disease epidemiology and symptoms, host range and geographic distribution along with management options and genomics.

In addition, this research team delved further into the literature and developed a review article published by APS Press in the journal Plant Disease.
