I would think it’s a joke. I’ve sprayed all the chemicals for 25 years and before that grew up on a farm where the sprayer was a car with the body cut off. Tank and booms put on. All the farmers up here did the same. No I did not follow safety directions and most people don’t. I was careful with the bug killers because they would sometimes be dead when you made the next pass. No case has proven this product causes cancer they just got a McDonald’s hot coffee jury in suburbs and went with it. Ed k
