Welcome
Research Interests
We are a research lab at the University of Massachusetts Amherst Stockbridge School of Agriculture specializing in:
-
Population genetics of New England populations of Sclerotinia homoeocarpa, causal agent of dollar spot on turfgrass, to better understand population dynamics of fungicide insensitivity
-
Management of fungicide resistance in dollar spot on turfgrass
-
Classical and molecular breeding of disease resistance in Lolium and Agrostis spp.
-
Mapping of disease resistance quantitative traits in Lolium and Agrostis and comparative genomics analysis in Poaceae species
-
DNA fingerprinting of Kentucky bluegrass and bermudagrass
-
Nanotechnology for plant pathogenic fungi
Extension and Outreach Focus
In addition to research, our group is involved in extension work through:
- Educational talks on management of fungicide resistance and cultural practices for improved turf quality
- Fungicide and Product Field Trials for the turfgrass industry
- Diagnostic Site Visits
- Fungicide Resistance Assays to measure levels of fungicide resistance and reduce financial and environmental impact of fungicide use on dollar spot.
- DNA Fingerprinting of turfgrass using molecular markers
- Publication of extension articles
News
Snow mold applications were made in five locations from Nov 5-Dec 3th. This year we have trials in Maine, Massachusetts, New Hampshire and New York and will evaluate the affect of 60 products for snow mold damage and spring recovery. The picture above shows some of the experimental plots after fungicides and pigmented treatments were applied at Glens Falls Country Club.
The Jung lab sends out disease updates through the UMass TurfTalk email list to members of the turf community in New England. These brief reports will keep the reader up to date on management, forecasting, severity, and general information on turf diseases throughout the season. To get on the email list, email us at: turf@psis.umass.edu
