Summary

​Many symptoms are associated with cotton leafroll dwarf virus (CLRDV), including shorter or taller plants, wrinkled leaves, misshapen bolls, and excessive fruiting. Infection timing may be related to where bolls are located on plants. Specifically, with early infection, boll loss may occur from the bottom of the plant up. With late infection, there may be good boll set on the bottom of the plant but excessive fruiting toward the top and a lot of boll abortion. Although measures have been taken to assess yield losses associated with the virus, no real conclusions can be drawn from the data collected at this time.
