    Q
    How much of Barricade 4FL should I use in a 1 gallon sprayer?
    The label does not give specific info about mixing small amounts.
    A
    Herbicides are much different than other chemicals because water just acts as the carrier. In this case the product label recommends  you use .23 - 1.1 oz per 1,000 sq ft to be treated. Please read the product label to determine the exact usage rate for your needs as it varies according to the species of grass you have. Once you have determined the usage rate per 1,000 sq ft you can follow the outlined steps to decide how much water you should use per 1,000 sq ft (this will vary for every person as the type of equipment will be different and the walking speed of the applicator will be different).
    1.Mark off an area that is 1,000 square feet (i.e. 20 by 50 feet or 25 by 40 feet).
    2. Place the sprayer on a level surface and add water (no herbicide) noting the final level of water in the spray tank.
    3. Spray the marked 1,000 sq ft  area with a sufficient volume of water to provide uniform coverage.
    4.Refill the spray tank with the amount of water it took you to cover the 1,000 sq ft area
    5. Add the pre-determined amount of herbicide that is needed to cover the 1,000 sq ft area to the spray tank.
    Example: If the sprayer uses 1 gallon of water to cover 1,000 square feet and the desired application rate of the chosen herbicide is .80 fluid oz./1,000 square feet, then you would add .80 fluid ounces of the chosen herbicide to every 1 gallon of water to be used.

  • Asked by Brenton from San Jose Ca

    Q
    Can Barricade 4FL Herbicide be used around a fruit tree and vegetable garden?
    A

    Barricade 4FL Herbicide should be applied a few feet away from fruit trees and vegetable gardens. Also, it would be best to cover the garden if possible to be sure that no drift spray touches the growing plants. You may want to consider a product like Monterey Vegetable & Ornamental Weeder or Prowl H2O Herbicide. Monterey Vegetable & Ornamental Weeder is a pre-emergent herbicide that helps to control grasses and broadleaf weeds. This is one of the only products that is safe to use in vegetable gardens and can also be used in flowers, trees, shrubs, groundcovers, and rock gardens. Prowl H2O contains Pendimethalin as its active ingredient, which provides broad-spectrum residual control of annual grasses and certain broadleaf weeds in more than 100 crops.
