Hi-Yield Weed and Grass Stopper with Dimension Herbicide - Questions & Answers

We do not know the setting for that spreader and we are not sure exactly what to set it on.  However, almost all fertilizers, herbicides, insecticides, etc have treatments in amounts of so much product per 1000 square feet.  So if you can figure out what your walking speed is then you know anytime you apply any product that calls for so much of it per 1000 square feet, you always set your spreader on this setting.  You can calibrate this by marking off a 1000 square foot (10 x 100) area and placing 2.4 pounds of any type of product of similar granule size, or of the Hi-Yield Turf & Ornamental Weed and Grass Stopper itself in the spreader.  Start with a low setting and start walking your marked off area at a normal pace.  You can adjust as you go and find the basic setting for you to apply the product over a 1000 square feet. You can call VPG, the manufacturer, and they may be able to tell you what setting you should have it on.  You can reach them at 888-583-5296.

Hi-Yield Weed and Grass Stopper with Dimension Herbicide is labeled for use on both St augustine and bermuda grass so it will not work to stop the germination of Bemuda.
Unfortunately Bermuda grass is so closely related to St. Augustine grass that there is nothing that will remove Bermuda from St. Augustine and not hurt the Bermuda as well.  In your situation it is recommended to spot treat the Bermuda with Round Up and kill it directly, and then replant St. Augustine in those areas.
