Dave from Poughkeepsie, Ny writes,

Problem w concentrate dispenser?

I sprayed the lawn for about 30 minutes continuous and the bottle is only 1/2 empty. I am afraid venturi system isn't working correctly. Should I re-apply again with another bottle I purchased. I don't want to damage the lawn. How long does this product typically last before empty?


You can do a second treatment after two weeks with the Bayer Advance Crabgrass Killer for Lawns RTS if necessary. The amount of the product you use will depend on your lawn size. An average bottle treats 5000 sq. ft. Please let us know if you have any additional questions.
