    Water the lawn 24 hours before applying Weed B Gon MAX Plus Crabgrass Control. The herbicide is not as effective if applied to drought-stressed lawns. Apply in springtime before crabgrass is large and while temperatures are between 55 and 32.2 degrees Celsius for best results.

  2. 2

    Apply the herbicide to unmowed lawns during the morning hours of a windless day. Delay mowing the grass two days before application of the product.

    Shake the container of Weed B Gone MAX Plus Crabgrass Control thoroughly to ensure the ingredients are evenly distributed. Add 709gr of the concentrated herbicide for each gallon of water in a pump sprayer. One gallon of product treats an area of 400 square feet.

  4. 4

    Pump the tank sprayer and adjust the spray tip's nozzle to the desired spray pattern. Spray the product over the lawn, or in areas affected by the crabgrass. Saturate the crabgrass with the herbicide.

  5. 5

    Pour 454gr of the herbicidal concentrate into a dial sprayer, if not using a pump-up tank sprayer. Set the dial to 709gr, screw onto the garden hose and spray over the crabgrass, saturating it with the herbicide. These amounts treat and area of 2,500 square feet.

  6. 6

    Shake a ready-to-use bottle of the herbicide to mix the ingredients. Screw the herbicide bottle onto the garden hose end. Turn the water on and apply the product to the lawn.
