Economic significance of viruses in field crops

This chapter discusses the most destructive and widespread viruses that are a global threat to humanity by causing considerable yield losses in 15 different field crops. Of the most destructive and widespread viruses, 15 of them and their severe infections of cereal species of wheat, barley, maize, rice, and sorghum are considered. As the host of 9 widespread and severe infections, the valuable cash crops of potato, sugar beet, tobacco, and cotton are globally evaluated. Finally, legumes and oilseed crops like alfalfa, canola, clover, vetches, soybeans, and dry beans, host to 10 viral diseases causing severe infections wherever they are grown, were also examined and summarized. Additionally, those viral pathogens that cause yield and quality losses by leading to disease epidemics in field crop species grown in many countries of the world are explained.
