From a personal experience (I'm a farmer) the concentrations used in a residential context are exaggeratedly above the recommendation. They are mismeasured and generally high.
Plus, glyphosate preparations need to be corrected in pH (below 5 for maximal efficacy), which is something many people don't do.
The professionals doing weed control in cities absolutely must have training and adequate PPE. The same thing applies to pest control.
I'm not against professional usage of pesticides, but I would be OK with forbidding most insecticides and herbicides for personal usage. The every day insecticide spraying can? That thing is poison. Does anyone use a FFP2 mask or even a simple cotton mask? Many permetrine-based insecticides don't even mention that this active substance is specially deadly to cats.
