Extract from Wikipedia article: Peronospora viciae is a plant pathogen. It is a downy mildew that can infect pea plants.
Peronospora viciae is a downy mildew fungus that infects legume plants, particularly vetch and pea species. In East and Central Texas, it has been found to cause disease in wild and cultivated legumes, with symptoms including yellowing leaves, stunted growth, and white fungal growth on the underside of leaves. The fungus thrives in cool, moist environments and can be dispersed by wind-borne spores, leading to widespread infection in susceptible hosts. It is commonly detected in the region's agricultural fields, gardens, and natural areas during the spring and fall months.
