Some of the guys I scout for, still do not understand you can not have a marestail in cotton when you plant it.(Only using roundup for burndown.) The marestail are at least 4in. tall now. And I would like to get rid of them now.

Anyone have a good idea on how to kill these weeds in small cotton?

By the time we can use envoke over the top the marestail will have caused a lot of yield reduction.

I am thinking of Ignite under the hoods. Or maybe Gramoxone??
