The World Health Organization labeled glyphosate as a probable carcinogen because it causes cancer in laboratory animals and damages the DNA in human cell cultures. Also because it has been linked to non-Hodgkins lymphoma in agricultural exposures in the US, Sweden, and Canada. If we use this chemical in our yards it will be in our drinking water. We don’t need it!
The best way to fight weeds is by having good soil culture and outcompeting them with the plants (including grass) that you want. Pulling them out with a great weeder can work. But sometimes they pop up on our driveways and patios, or are resistant and invasive and we need a little help. Cutting the weed back and painting the stump with horticultural vinegar (20% acetic acid) or clove oil is a good solution. But if you want to just reach for a bottle of something, here are some options. Burnout is citrus oil and clove oil, Avenger is citrus oil, and A.D.I.O.S. is sodium chloride-salt. I would limit A.D.I.O.S. to spot treatments to limit the salt load to wells and streams.
