Derrick, Department of Plant Pathology and Crop Physiology, Louisiana State University Agricultural Experiment Station, Baton Rouge 70803. L. D. Newsom, Department of Entomology, Louisiana State University Agricultural Experiment Station, Baton Rouge 70803. Plant Dis. 68:343-344. Accepted for publication 14 December 1983.

A disease that caused severe bud proliferation and delayed maturity of soybeans (Glycine max) was found in Louisiana. The disease was found to be transmitted by the leafhopper Scaphytopius acutus. Pleomorphic membrane-bound bodies were observed in ultrathin sections of diseased tissue, indicating the disease may be caused by a mycoplasma. The disease is referred to as soybean bud proliferation.
