Of the two leading products, Zonastat-H and GonaCon Equine, Gonacon will outpace Zonastat in use, for the following reasons:
- May sterilize treated mares
- Applicators need not be certified
- Can be misused with no consequences
- Few if any limitations on where it can be used
In the first part of the June 14 roundup schedule, for nonmotorized removals, the two products are more-or-less evenly split.
Given that GonaCon Equine can be used to control or eradicate pests (wild horses and burros) that interfere or could interfere with animal agriculture (permitted grazing), which is not true for Zonastat-H, it will become the pesticide of record until something better comes along.
