Glyphosphate has become so prevalent in water sampling it's a standard element of the assay performed here now.
Rule of thumb is anything Monsanto states is a flat-out lie. That's the dictate the chemists at my State Health Dept. employ in their work - all data starts from ground zero, no extropolating from industry-supplied information. Sad state of affairs, but very wise.
I let Monsanto work on a forty-acre test at my old place, giving them the benefit of a doubt based on their claims to have developed a binding componant of an ester formulation for R.U. After all was said and done and one year and five repetitive trials later, it became clear they were hiding the fact that resistance has developed in targets and they simply "upped" the dose to attempt a reaction. Complicated and simple lies from a Fortune 500. The state has started a criminal investigation but Texas is pro-chem industry, nothing will become of it except a lot of money spent.
