NE_Weeds - 2/13/2024 18:47  Dicamba does have some residual properties, it's not much but will provide roughly 7-14 days of residual activity. It all depends on the amount of moisture you get after your application. This is why I like running dicamba in my PRE programs for some knockdown while providing a little cushion until you get enough moisture to activate things like Harness, Zidua, or Dual.
