Peronospora radii is a floricolous downy mildew which infects plants in the Asteraceae.[2] It disfigures the inflorescence, mainly causing symptoms in the ray florets, but can also be visible on the leaves. It forms greyish-violet conidia. It has been reported from hosts in the genera Achillea, Anthemis, Argyranthemum, Chrysanthemum, Coleostephus, Cota, Glebionis, Leucanthemum, Matricaria, and Tripleurospermum.[1]
