Anthracnose and Dollar Spot Fungicide Resistance Testing
Fungicide resistance is a growing problem on highly managed turfgrass and we can determine if your site has developed resistance. Testing is conducted at the UMass Turf Pathology lab using all commonly used fungicide classes to test for fungicide resistance. Results will give clients a precise understanding of the fungicide resistance levels on their site and potentially save thousands of dollars in misapplications of fungicides.
Please contact email@example.com for information on the sampling procedure.
The cost of the test is $400 and consists of traditional and molecular approaches to diagnose resistance. A phone consolation will be conducted after testing has been completed and a final report will be sent out shortly after.
Fungicides Classes Tested (fungicide class and all active ingredients that belong to that class): Active ingredients are selected based on published fungicide resistance monitoring/detection studies.
Anthracnose: Benzimidazole (thiophanate-methyl), DMI (metconazole, myclobutanil, propiconazole, tebuconazole, triademefon, triticonazole), and QoI (azoxystrobin, fluoxastrobin, pyraclostrobin, trifloxystrobin).
Dollar Spot: Benzimidazole (thiophanate-methyl), DMI (metconazole, myclobutanil, propiconazole, tebuconazole, triademefon, triticonazole), dicarboximide (iprodione and vinclozolin) and SDHI (boscalid, fluxapyroxad, and penthiopyrad).
Fungicide and Product Trials
As a service to the turfgrass industry, the UMass Turf Pathology lab conducts field trials throughout New England to test the efficacy of fungicides and other turf products in controlling various summer and winter diseases. For cost information contact firstname.lastname@example.org.
Products will be tested for field efficacy on a Poa annua / Agrostis stolonifera putting green. The experimental plot will be located on a golf course practice green. Fungicide applications will begin late May on a preventative basis.
Fungicides and other products are tested for their field efficacy on a colonial bentgrass fairway from June to August. Applications are made over a two month interval depending on disease pressure and company requests. Weekly ratings of % disease cover and phytotoxicity take place and photographs of each plot are taken at each rating.
We offer a wide variety of dollar spot product testing options and can accomodate most requests. We specialize in testing on sites with confirmed fungicide resistance. Applications are made depending on disease pressure and company requests. We conduct weekly ratings of infection centers, phytotoxicity, turf quality, and photograph each plot.
A test plot of Perennial Rye is planted mid-June and the trial will begin the first week in July to test field efficacy of a variety of fungicide treatments and other products for foliar Pythium blight control. Applications are made depending on disease pressure and company requests. Weekly ratings of % disease cover and phytotoxicity take place and photographs of each plot are taken at each rating.
Field trials are conducted at four locations throughout New England to test field efficacy of various products used to control snow mold under differing levels of disease pressure and species causing disease. Control of Typhula blight (caused by Typhula ishikariensis and T. incarnata) and pink snow mold (caused by Microdochium nivale) is tested on golf course fairways and one putting green each year. Products are applied in mid November before snow fall and % disease rating of plots as well as measurements of phytotoxicity are made in Spring right after snow melt. Photos of each plot are taken and a book of research results is published in the spring.
Diagnostic Site Visits
We offer site visits for home owners and golf courses to provide a more hands on approach to diagnosis of diseases and other common turf related problems. Many problems cannot be properly identified without laboratory diagnosis, therefore, a site visit is best accompanied by a laboratory report. To schedule a site visit, contact us.
Cost: $300/visit plus mileages for site visit and written report
Turfgrass DNA Fingerprinting
We provide fee-based services on DNA genotyping/fingerprinting of turfgrass using molecular markers. It is very difficult to differentiate cultivars within the same species or in a blend (for example, cultivars of Kentucky bluegrass or Bermudagrass) by looking at seeds or turf stands. Therefore, DNA fingerprinting will make it possible to accurately identify cultivars. DNA fingerprinting can be applied for:
- Seed Purity
- Seed or clonal cultivar identity
- Cultivar identification within a blend
- Off-types in sod or vegetative cultivars
DNA fingerprinting services have been used by forensic scientists in golf course theft cases. In one instance, the grass cultivar identified on the wheels of a stolen vehicle was traced back to the course from which the vehicle was stolen from!

Organic Seed Variety Trials
With nearly unlimited agricultural resources available to us here at UMass, we can evaluate experimental and commercial tomato varieties. We handle conventional and certified organic production from seed to harvest, including all field preparation, plant maintenance, harvest, and data recording. These services are of high value to seed companies due to the limitless scientific and professional applications.
