Horsepower Herbicide

Powerful Control without 2,4-D

Horsepower Logo
Horsepower® is a three-way, selective post-emergent herbicide that controls dandelions, chickweeds, knotweed, clover, cocklebur, plantains, oxalis, spurge and a wide range of other broadleaf weeds. With its highly concentrated formulation, Horsepower treats up to 4 acres per gallon. And since Horsepower doesn’t contain 2,4-D, it’s an ideal weed control solution for 2,4-D sensitive areas.
