Have used Callisto (and generics) for post many times before but never for pre.     Looking at adding it in with Surpass and dicamba.


Does using 3 oz pre and then another 3 oz post add a lot of concern for carryover or does the fact that the 3 oz pre goes on 4-6 weeks earlier do away with extra carryover concern?

Hopefully that is clear enough to be understood.   

 
Basically I'm wanting to know if 3 oz pre followed by another 3 oz post has a lot more carryover risk (for soybeans) than just running 3 oz post.    We have seen carryover damage in beans from 3 oz post before, but that was in 2020 after the 2019 corn crop had the post sprayed really late because of being planted really late.   I'm hoping we don't get to that point this year.


I know GT/LL/27 beans can be used where carryover is a concern but it seems like they are getting harder and harder to find as time goes on.  I'm worried they might not be available at all pretty soon, maybe as soon as next year.
