Interpretive Summary: Sugar beet is susceptible to a number of different viruses that can be transmitted by insects, fungi, nematodes, seed and/or physical contact. In this book chapter describes viruses which infect sugar beet. All of these viruses have the ability to decrease the potential yield of the root crop as well as affect the extractability of sugar by the processor. Certain viruses such as Beet necrotic yellow vein virus (BNYVV), the causal agent of rhizomania, have seriously damaged sugar yields in intense sugar beet producing regions of the world and this virus can dictate where beet can be grown if partially resistant varieties are not used. With the advance in molecular biology, most of the economically important sugar beet viruses have fully characterized and their DNA or RNA genomes sequenced. This has been particularly useful in understanding how theses viruses interact with plants and their vectors, and how they can be better controlled in the future. Such advances have enabled the development of highly specific and sensitive serological and molecular diagnostic methods that have helped to clarify the taxonomic position of certain viruses and their strains, such as the virus yellows complex, as well enabling the identification of new viral species and how sugar beet viruses can interact in the same plant.
