Q: Is there a non-Monsanto equivalent to Roundup?

A: There are several alternatives to Monsanto-made Roundup. Remember that glyphosate, the active ingredient in Roundup, is no longer patented by Monsanto and is manufactured or sold by several companies.

You could use Bonide KleenUp or Hi-Yield Kill-Zall instead of Roundup. Here is a source list for glyphosate (click for sources).

Non-glyphosate plant-killing substitutes include herbicidal soap (Bayer Natria Grass & Weed Killer), citrus oil (Nature’s Avenger) and clove oil (BurnOut).
