Product Q&A

Answer:

The reason that herbicides do no list a specific amount per gallon of water is because the dilution rate is different for everybody.  It depends on what equipment you are using.  The more important thing is how much of the product is placed out over 1000 square feet.  When applying herbicides, we always recommend using calibrated equipment, rather than hose-end sprayers, to avoid uneven application or damage to desirable plants. Most herbicide labels will list how much active ingredient should be used per 1,000 square feet. To calibrate your equipment, for example, a 1 gallon sprayer, mark off an area of 1,000 square feet, and cover that area at your normal pace as evenly as possible. If you used the entire gallon, you would use the recommended amount in 1 gallon of water. If you only use ½ gallon to cover the 1000 square feet then you mix the recommended amount on the product label in a 1/2 gallon of water.  So if an acre is basically 44,000 square feet and the product label calls for 5 ounces per acre for fescue, and you used 1 gallon to cover 1000 square feet, then you would mix 5 ounces of Dismiss in 44 gallons of water.  Ultimately, correct timing and application rates are more important than how much water is used to apply your herbicides.
