What is application rate of Drexel Diuron 4L Herbicide per gallon?
Drexel Diuron 4L Herbicide
is mixed at 0.6 - 4.8 qt. per acre. Herbicides are a lot different than other concentrated products and can be hard to understand at first. The application rate depends on the the type of turf you have and how quickly you apply the product. You will need to read the product label
to determine the correct usage rate for your needs (you did not give us any information about the type of lawn, region or application program you will be using so we cannot give you exact rates). The amount of water used to apply Drexel Diuron 4L Herbicide is not critical, but should be sufficient for uniform coverage of the target area. Calibrate by determining the volume of water required to treat 1,000 square feet. Use this calibration volume to determine the amount of water and Drexel Diuron 4L Herbicide needed to treat the target area (see the following calibration example). Note: Sprayer calibration (volume of spray needed to treat 1,000 square feet) will vary with each individual operator.
Steps in Calibration:
1. Mark an area of 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 noting the final level of water in the spray tank.
3. Spray the marked area with a sufficient volume of water to provide uniform coverage. Refill the sprayer to the same level as before measuring the amount of water added. The measured water added to the sprayer is the volume needed to cover 1,000 square feet.
4. Determine the application rate for Drexel Diuron 4L from the product label.
If you still find you need help figuring out the correct usage rate (we know this label is confusing) please don't hesitate to call us and let one of our customer service representatives help you 866-581-7378 (M-F 9-5 EST)
