Technical Abstract: Viruses are among the simplest in composition of the pathogens that infect peanut. They consist primarily of nucleic acid and protein. The nucleic acid carries the information to cause disease. The protein coats the nucleic acid to protect it and is involved in the uptake and transmission of the virus by vectors. Vectors are the insects, nematodes, and fungi that tcarry the virus from plant to plant. Most viruses are transmitted by one o a few species of a specific vector. Although viruses are simple in composition, they are probably the most difficult pathogens to manage and control. There are no curative agents that can be applied to plants to control virus diseases, so management practices must be directed toward preventing the crop from becoming infected or toward keeping initial disease from spreading. In developing management strategies for control of plant viruses, an understanding of the relationship of the virus with the crop, the environment, and the vector is necessary.
