Roundup is a brand covering different herbicide formulations. Do not assume every product contains glyphosate: U.S. residential lawn-and-garden formulations have changed, and older products may remain on shelves.
Read the container
Identify the active ingredients and follow that product’s current label, including application limits and precautions. Research on glyphosate alone does not establish the effects of every Roundup formulation.
Avoid spraying bees and flowering plants they are visiting. Preserve useful flowering habitat and consider targeted or manual weed control.
