I have used the Sedge Hammer for those already emerged but still have growth appearing throughout the summer. Exactly how does the Pennant need to be applied? Would more treatments need to be spaced out over the summer to hopefully be free of any more emerging nut sedge?
You can apply Pennant Magnum once or twice annually before weeds emerge for complete nutsedge control as long as you do not exceed the total of 4.2 pints/Acre (46 mL/1,000 sq ft) per year or crop cycle, whichever is less. Use higher label rates where yellow nutsedge is expected. You will use 14-28 mL/1,000 sq ft depending on your soil texture and level of expected weed infestation. If you are able to apply Pennant Magnum before you start seeing nutsedge in spring, then you will see better results than if you wait to make a first application after you are already seeing the new plants come up. Please refer to the product label for complete application instructions.
