John R. Street, Deborah D. Holdren, and David S. Gardner. The Ohio State Univ, 216 Howlett Hall, 2001 Fyffe Ct, Columbus, OH 43210

Foliar fertilization with nitrogen had a positive effect on reducing dollar spot ( Sclerotinia homoeocarpa ) incidence.  Trinexapac ethyl alone or in combination with nitrogen had no effect on dollar spot incidence.  Paclobutrazol decreased dollar spot incidence alone and in combination with nitrogen.
