If the volunteers and contractors applying two doses of GonaCon Equine to wild or captured mares are not certified according to EPA standards, they, and the agency overseeing the work, are following the 2017 registration.
If they are certified or they’re applying the doses 30 days apart, they’re following the 2013 or 2015 registrations.
As of today, the product is not an RUP, persons applying it need not be certified and the minimum interval between treatments is 90 days.
Mares in these herds were likely subject to the 30-day window, contrary to federal law:
If the field office overseeing the work did not require the persons applying the pesticide to be certified applicators, then they were following the 2017 registration and should have known about the 90-day window.
HMAs subject to field darting, such as Hog Creek, Cold Springs, Sand Springs and Coyote Lake/Alvord-Tule Springs in Oregon, Piceance-East Douglas in Colorado, and Onaqui Mountain and Range Creek in Utah should also be investigated.
