Editor's Note: This article originally appeared in the November 2025 print edition of Nursery Management under the headline “Herbicides.”

This summer, Nursery Management magazine surveyed 150 growers across North America to learn more about weed management procedures including scouting, herbicide use, budgets and more. Survey respondents hailed from 35 states plus several Canadian provinces. The following pages reveal what your peers are doing at their own operations, as well as which weeds are the most problematic.

Editor’s note: Last year, 75% of survey respondents said they rotated herbicides. This year, that number has declined to 61%.
Editor’s note: Bit of a flip here from last year’s survey, in which 55% of growers had experienced resistance.
Other answers included hairy fleabane, bittercress, annual bluegrass and poison hemlock.
Editor’s note: That’s two straight years of horseweed and nutsedge being the top two weeds fighting back against herbicides.

Other answers: mostly organic growers, concerns about use with water recycling system
Editor’s note: Last year, 89% of growers who took this survey reported using a pre-emergence herbicide. This year, that number dropped to 73%. It seems like there’s an opportunity here to serve growers who can’t find a compatible herbicide with their crops.
