Plant Protectants?

My husband and I don't golf, but we went on a hike in May that included some golf paths in its first few miles.  As we were walking along, we came across this sign.  I was amazed and had to stop and take a picture. (Okay maybe I needed a little rest on the hike as well)  I had never heard of the term, plant protectants, before. Doesn't it make you feel all warm and cozy?  Sounds a lot better than herbicides and insecticides doesn't it?  The solicitous grounds crew is busy protecting the plants, not the grass has just been sprayed with something that may be dangerous to you.  Just goes to show you that marketing is everything.
