Fungicide Resistance Assays for Dollar Spot on Golf Course - brochure

Dear Golf Course Superintendent Association,

My name is Geunhwa Jung, Turfgrass pathologist at UMass and I would like to tell you about a new and exciting project the UMass Turfgrass Pathology Laboratory is starting in the summer of 2011.  Over the next two years we will begin work on establishing a dollar spot fungicide resistance database in the New England region.  This work will entail sampling dollar spot infection centers (50 per golf course) from New England golf courses and assaying for fungicide resistance to the benzimidazole (thiophanate-methyl), DMI (propiconazole), dicarboximide (iprodione and vinclozolin) and SDHI (boscalid) fungicide classes.  Recent research has shown that each golf course contains a unique dollar spot population structure in which fungicide resistance varies and laboratory confirmation is required to accurately predict which fungicide classes will provide effective control.  We are looking for golf courses that may be interested in this project and would like to present the project outline at superintendent association meetings.  We have submitted a grant proposal to the New England Turfgrass Research Foundation that is also attached in this email.  We like you to review the proposal and let us know if this project is something that may be of interest to the superintendents in your association.  Thank you in advance for you time.

Sincerely,

Geunhwa Jung
