Summary

There are two parts to this presentation on soybean viruses. Part 1 covers the most common soybean viruses, with an emphasis on identification of each disease. An overview and introduction to viral diseases is presented, along with information on how each virus is transmitted. Part 2 focuses on management options for soybean viral diseases. Management options are discussed in general terms that suggest ways to avoid or reduce vector populations. Genetic resistance to viral disease is discussed, and the sources of viruses are discussed in terms of how to reduce potential introductions.​
