The product comes in a liquid form and covers an area of approximately 2,500 square feet per 2.5-gallon container, offering a decent coverage area for medium to large-sized properties. The herbicide's effectiveness in controlling high-anxiety woody species like cherry, loblolly pine, mesquite, red oak, sweetgum, and Scotch broom is a strong point, as these can be particularly challenging to manage with less potent products.

Its application involves diluting the water-soluble concentrate based on volume percentage, ensuring broad-spectrum control over a wide range of weeds like crabgrass, ryegrass, and bermudagrass, to name a few. However, it's important to note that it only affects emerged weeds, offering no residual control, which means that weed seeds in the soil will continue to germinate after application. The product covers an area between 400 to 4000 square feet, making it suitable for both small and extensive areas.

With a liquid volume of 2.5 gallons and a weight of 25.4 pounds, it is manageable for most users. One notable advantage is its effectiveness, but users should be prepared for the environmental impact and safety precautions typical of chemical herbicides. Careful handling and adherence to safety guidelines are essential to avoid adverse effects on non-target plants and the surrounding environment. Also, since it does not offer residual weed control, repeated applications might be necessary to manage new weed growth.
