I think there is a very good chance DD is breeding resistance to Glysophate - just as Min Till bred resistance to Atlantis
I bet within a few decades we'll see Glysophate resistant weeds on DD farms
Nature promotes the strong - not seen a Weed resistant to a plough
maybe but under my sfi rotation i will only be using glyphosate once a year - hardly excessive or more than many who cultivate do
if resistance happens im sure we will find alternative methods
