Abstract

In 2016, a country-wide virus outbreak was observed on legumes in Germany. Severe yield losses were reported in some cases. For the very first time, Pea necrotic yellow dwarf virus (PNYDV), a nanovirus, was not only found nationwide on peas in Germany but also infected faba beans, lentils and vetch. PNYDV was so far only found in few geographic regions of Germany. PNYDV as well as other legume-infecting viruses are mainly aphid-borne. It is expected that climate change will lead to milder winters in Germany therefore aphid flight periods will be extended. Furthermore, more aphids can overwinter as adults thus potentially enhancing virus incidences on legumes.
