I figured the active reference would keep out the commons. Does anyone have any luck with a timing on app or amount active per acre to deter bermuda spreading in the transition zone? Mainly granular guys here in Va and they don't want to deal with spraying acclaim ($) or glyphosate (time). Not looking for a cure, was just curious because i had heard some things about the barrier in the soil detering bermuda branches from re-rooting and spreading. I have seen it do a little good in my yard and accounts and in places that were heavily overseeded year over year.
