I started clean and had good metribuzin and Fierce pre out when I planted. I have made 1st pass with Roundup Powermax and Zidua 12 -15 days ago postemerge to the small beans.  It was 10 days before we got rainfall for Zidua incorporation.  Getting ready to go back with second glyphosate application. I feel like I need to use something that might get a small pigweed just coming up and would give me some more pre for them. We are in region one for the Reflex. Reflex vs Flexstar. Does Flexstar have better killing power on the small pigweeds over the Reflex or the generic? Will be using dry AMS with the Power Max. Beans are 5 to 6 trifoliate. I know the Prefix tends to burn the beans pretty good sometimes but what about these mixes that won't have the Dual in them?
