Growth of field areas under oilseed rape increases the significance of virus diseases of this crop, causing decrease in yield and oil content. Economically the most important viruses of oilseed rape are Beet Western Yellows Virus (BWYV), Cauliflower Mosaic Virus (CaMV) and Turnip Mosaic Virus (TuMV). Other viruses like Cucumber Mosaic Virus (CMV) and Tomato Spotted Wilt Virus (TSWV) are less important. Disease intensity differs from year to year, and it depends on weather conditions during season, source of inoculum and vector population. Decrease in yield which is caused by these viruses can reach more than 70%. The elementary means of control include elimination of inoculum source, isolation from areas which contain inoculum, aphid control and growing virus resistant or tolerant oilseed rape genotypes.
