Subject: RE: Will Enlist get waterhemp by itself ?

South Central MN
Where I am it will make the waterhemp kink and curl but usually doesn't kill it, however run some Liberty (or generics) with it and they are toast. Even dicamba is having issues here, difference being you have a much bigger window and far less restrictions with the Enlist. (Here, not in cotton country!) I would say 50-75% of our waterhemp is immune to Roundup, perhaps 50% kill with group 2 herbicides, and even group 14 is not doing well. We have to run multiple modes of action to kill them, and not sure how long that will work for either.

I would not skimp on herbicide control for waterhemp, as it is like corn, except being male and female plants, it spreads resistant genes around very quickly, and mixes them very quickly as well. Worst case you are down to Christmas chemical (Ho ho ho) to get rid of them. Yes there are some cases where good old bean walking is the only way to get rid of the multi-resistant ones.
