Interpretive Summary: Pea enation mosaic - Pea enation mosaic virus (PEMV) AUTHOR: Lyndon D. Porter SYMPTOMS • Small spots or flecks on leaves • Severe stunting • Leaves and pods are malformed FIGURE 1 – “Windows” of yellow spots and streaks on distorted and curled leaves and close-up of “windows” on leaflets. (Photo credit: L.D. Porter) FACTORS FAVORING DEVELOPMENT • Virus-carrying aphids, such as the pea aphid, present and feeding on plants • Warm spring temperatures favoring early aphid development and migration • Infections at early growth stages are more severe IMPORTANT FACTS • All currently available commercial cultivars are susceptible to PEMV • PEMV is not seed-transmitted • Insecticides to manage aphids may reduce secondary spread of PEMV • Pea, lentil, faba bean and vetch are also susceptible • Commonly confused with thrips, herbicide or other virus damage Technical Abstract: Pea enation mosaic - Pea enation mosaic virus (PEMV) AUTHOR: Lyndon D.
