Turfgrass Water Conservation Alliance (TWCA) relies on our cooperators to conduct trialing. We recognize that our work is only a small part of what you do on your farm and that tracking the details of the study is not something you want to worry about. We also know you want to talk about all the cool and interesting work you spend your time on and we certainly hope TWCA is on the list of things you want to discuss.
To make it easier to express the scope and scale of the TWCA trialing we have created this list of talking points about the trial(s) TWCA is currently running.
2020 TALL FESCUE TRIAL
What are the 4-digit numbers in the “Published List”?
When membership ends mid-trialing the cultivar names are removed from the trial. The cultivars remain a part of the evaluation but are ineligible for qualification until membership is resolved.
Does TWCA require Turf Quality scores?
Absolutely. Not only does TWCA collect turf Quality (TQ) scores on the trials (outside the drydown period) but we also require our members to have TQ trialing on hand in the event someone has questions about the overall quality of a cultivar. All cultivars must have ACCEPTABLE turf quality for TWCA qualification.
Has TWCA looked at the interactions between drought and other factors?
Yes! TWCA, working with cooperators has looked at turf performance under drought and in combination with other factors including:
How does TWCA choose standards?
Does TWCA use fungicide?
Yes. TWCA currently uses Heritage to control fungal infections in trialing. In the past TWCA utilized Tilt but, when a colleague pointed out the potential for growth regulation TWCA switched to the current recommended regime
Are all TWCA trials maintained the same way?
Yes! TWCA has created a Cooperator’s Maintenance Manual outlining the guidelines for installing, establishing and maintaining the TWCA trials. TWCA also holds 3 regularly scheduled cooperator calls to ensure all cooperators are maintaining the TWCA trials the same
What cultivars are Qualified?

TWCA relies on membership dollars to support drought research across North America. Please help conserve water while preserving the ecological benefits of turfgrass in the managed environment.
