What in the world are superweeds? Superweeds are weeds that become resistant to herbicides. The scenario is similar to to different viruses become resistant to antibiotics.
To destroy superweeds, a farmer has to kill them the old-fashioned way by plowing the land. Basically, all weed killers on the market are obsolete because the weeds become resistant. Then, the weed killers no longer work. That’s why taking shortcuts in tending your garden never works. Do not waste your money on weed killers.
Plus, you could end up with cancer when using herbicides to kill superweeds. Over 50,000 people throughout the world have sued Monsanto because their weedkiller RoundUp gave them cancer.
