John,
But the lawsuit does not allege Chlorpyrifos use or misuse, correct? Why lump that insecticide with the herbicides the lawsuit lists? 

I think of it like this... when I am using a miter saw to cut wood at work, I wear safety glasses, gloves, ear protection and have a working knowledge of the saw and how to use it right through training and experience. But I don't complain and file a lawsuit if my boss doesn't train me on an arc welder that I am not using, but it might be used in the next room over in the shop. And I don't file a lawsuit when my boss doesn't give me leather gauntlets and a welding face shield for my miter saw if I am not using the welder or in the vicinity of the welder.

I will be waiting to see the details of the case, not just the allegations! Because these are very serious allegations!
