GO NON TOXIC WEED KILLER
GO SHOPPING BURNOUT WEED KILLER
I cannot speak from experience here, but I do get a lot of hits when searching for non toxic weed killer.
From what I have researched on this subject, the BIG AG companies have agents in the field working with farmers to help them with their farm business and of course, steer them toward BIG AG products.
BIG AG is like BIG PHARMA, BIG TOBACCO, ETC.
Uses their influence to benefit their business segment.
