The cotton leafroll dwarf virus causes yellowing and distortion of leaves (Figure 1) and is believed to be vectored by the cotton aphid (Aphis gossypii) during feeding (Figure 2). A litany of other symptoms has been attributed to the virus including missing fruit and bolls, over-tall plants, reddening of veins, dwarfed plants and leaf cupping. In some situations in the southeast United States, significant yield losses have been attributed to the virus.
