I'm just northeast of cincinnati ohio. And I'm not mr safty that' not what I'm getting at just getting real world information of the health risks from the guys that do this every day. When I'm out mowing I can smell the guys spraying a lawn a block away. I have to wonder what 20, 30, 40, years of that feels like to breathe lol. Also is granular fert and spot spraying safer? In other words less airborne? Or is granular fert dusty at that volume of application?
