What Is The Best Weedkiller For Horse Pasture?

Horses are vegetarians, and foragers who are designed to roam over hill and down dale, finding the best grazing as they go. But horses can eat things that aren’t just grass; their gut is designed to make the most of the nutrients they get, so they can survive on limited grazing and scrubby pickings for a surprisingly long time.

But what about horses that are kept in one place, and cannot roam about? What if said place is plagued by weeds that overtake the grass and make it difficult for the horse to find ANY decent grazing at all? Well, that’s where the best weedkiller for horse pasture comes in. It is important to get rid of weeds that may be harmful to horses, as well as those that overtake the grass and prevent it from growing.

    • On the Amazon website it is advertised as a weed and GRASS killer. It contains vinegar, which will kill grass. I would not put this on my pasture.
