I talked to a local golf course. It's an 18 hole public course. Nothing fancy. They want an estimate to spray their fairways for dandelions ( no concerned about clover). They want a estimate per acre. It's a little hilly. I plan on using trimec. I have a Z-max with foamer. I have the lavender tips, 40 psi at 5 mph. Rate: Third of a gallon per acre What would you guys charge for something like this?
