Research
WTSC has a wealth of information made fully available to the public for research purposes.
Research
Genetics
Advances in genetic research help Washington turfgrass seed producers grow the latest varietals coupled with the ability to fight disease, stress, and perform to the highest standards.
Weed Control
Weed-free fields deliver weed-free seed at harvest. Research on controlling weeds during production helps Washington turfgrass seed producers deliver clean, genetically pure seed.
Disease Control
Disease control during production is imperative to ensure high-quality seed with maximum germination rates. Research helps Washington turfgrass seed producers develop best management practices to grow the finest product possible.
Water Use and Drought Tolerance
Research on drought tolerance and water use allows Washington turfgrass seed producers to grow seed that produces sustainable lawns and green spaces that stand up to drought and use less water.
Social and Climate
Social and Climate research helps Washington turfgrass seed producers understand the perception of natural turfgrass and the direct and indirect challenges to our society and environment.

Integrated Disease Management of Ergot in Kentucky Bluegrass (2020)
More Info
Our first objective was to screen novel fungicide chemistries for ergot control during anthesis. Ergot incidence and severity was low in field plots at both locations and a significant effect of fungicide treatment was not detected in either trial, but a few trends were observed at both locations.
Integrated Disease Management of Ergot in Kentucky Bluegrass (2019)
More Info
For the first year of validation, 238 data points were collected and analyzed. Overall, 91.6% of the data points agreed between rotating-arm spore samplers and the standard Burkard spore samplers. Sampling height was not a significant factor affecting sampling efficiency…
