PEMV is a virus transmitted by aphids. (I have yet to find a redeeming quality of aphids. Little bastards.) I have only one affected plant, so I really can’t complain too much. The leaves on this plant are puckered and feature the yellow mosaic pattern for which the virus was named. It is stunted (about half as tall as those around it) and the pods it has developed are leathery, lumpy, and very unappealing. There’s nothing I can really do about it. (Heavy sigh).
