RoundUp is the single most financially succesful pesticide in the entire history of the business. The bottle, ink, cardboard, tape, & freight way exceed the actual cost to manufacture the molecule. That said, the R&D, marketing, & insurance are what you pay for on any pesticide. The tech is rarely the biggest expense. I almost feel bad when the patents run out. I feel really bad when I think it could have been me that invented it. Keep the kids in school guys & gals!
