So im trying to build a spray rig for my ztr. Ok if the label is the law, and the label says 1 gallon of water per X oz of chemical to spread over 1000 sq ft of turf. Then how is it possible that the PG applies almost 1/4 of a gallon per 1000 sq ft? I understand it is low volume so do you put 4 times the chemical per gallon of water? Isnt that against the label?
