Labeled Crops
How to Apply
- 1). Using the included spoon, measure one spoonful per gallon of water. The included spoon measures 0.9 grams of SedgeHammer®.
- 2). Next, Add two teaspoons of non-ionic surfactant and mix thoroughly.
- 3). Each gallon of finished spray will cover 1000 square feet.
- 4). While spraying, periodically swirl or shake the mixture to keep the product evenly distributed in the water.
- 5). Use the entire gallon of spray mixture within 24 hours of mixing.
Non-Ionic Surfactants
A non-ionic surfactant is an additive that aids the penetration of Sedgehammer® into the plant tissue. Surfactants are not only used in horticulture but are commonly used in many cleaning products. Their properties enable products to “sheet” or spread across a surface. It is always recommended that a surfactant be used to help SedgeHammer penetrate the waxy layer of the nutsedge leaf. The surfactant also aids in dispersing the water droplets evenly across the leaf tissues and facilitates adsorption into the vascular system of the plant.
For best results, add a surfactant that is specifically made for horticultural purposes and labeled for use with an herbicide. If a nonionic surfactant is not available certain dishwashing detergents that contain high amounts of a nonionic surfactant may be helpful. Check the label of a dish soap to see if it contains a nonionic (not anionic) surfactant. The soap may contain both or just the anionic surfactant. If the label says it contains a nonionic surfactant, that is preferred. Dish soaps that are concentrated and are effective in grease dispersion often contain nonionic surfactants. Add the detergent last and mix by gently swirling together. See the”How to Use” page for more information.
Some commonly used nonionic surfactants are Hi-Yield® Spreader Sticker, No Foam A® , Latron B- 1956®, and X-77®.
