Thank you for your interest in the Hercules 20602! According to the manufacturer, the width doesn’t really matter as you can only use 2-4 pounds in a single application. For a field that big, it could use 4 pounds on the first week and 4 pounds on the second week though it might take a few days for you to see the results or the roots to die. It all actually depends on your stoppage. For partial stoppage, you can use 2 pounds while complete stoppage can use 4 pounds for 2 consecutive weeks. We hope this helps! Please refer to the specification sheet if you have more questions. Once you’ve made your selection, always remember to click Add to Cart to confirm your order, enter your zip code and you’ll be all set!
