Actually Corteva does have a existing encapsulated acetochlor in Fultime. It's a encapsulated acetochlor and atrazine mix. Fultime has been out a very long time with Dow.
Edit: looking at the label for the new Resicore XL you can put it on corn over 11 inches tall whereupon the label for the original Resicore limited it to corn under 11 inches tall. The 11 inch restriction was due to the unencapsulated acetochlor (Surpass) because it could cause crop injury.
