Product Q&A

Answer:

The amount of liquid herbicide required in the Chapin 20 Gallon Hose End Lawn Sprayer (G390) will depend on the specific RoundUp Herbicide you are using and the mix rates on that product label. Please view the example provided by Chapin from the G390 Manual.  Example:   If chemical product calls for 1 tablespoon per gallon and you want 10 gallons of finished spray, place 10 full tablespoons of product in bottle and fill with water to 10 gallon mark on side of bottle. For fan spray for lawns & shrubs, attach deflector to nozzle. For jet stream to spray trees, remove deflector.
