Round Up won’t do the trick?
My 41-percent Glyphosate Concentrate Grass and Weed Killer will do the job. It is the strongest that you can get without being a commercial Ag. person.
I will bet that Monsanto and the Chinese government have been working on this for years. Monsanto will license it and make money for making and killing it.
The Chinese will benefit when Biden gets into office and then will never ever have to worry about this kind of problem.
