OK. So we did our best. We sprayed a pretty lethal pre-emergent mix and took care of a lot of the pigweed. As it stands, we missed some rows. Pretty easy to see. Picture 12 clean(ish) rows and then 4 that have pigweed as tall as the sunflowers all across the field. We planted a bit late, too, so we are just now ready for some field maintenance. We used clearfield in half and plain black oils in the other half. We did NOT spray POST emergent. Yes, I realize that mistake but we had a myriad of excuses. Too wet. Not wet enough. No time. Too much time. Tractor broke. Moon wasnt right. Too early. Too late. Blah blah blah Then, its mid august.
So, the flowers are made. The leaves are dropping. We need to make dirt. The pigweed continues to grow and is certainly creeping into all areas of the field. We toyed with the idea of a highboy and some gramaxone and just burn it to hell. We also considered just bushhogging the 4bad rows and using our regular sprayer to cover as much of the "good" rows as we can. We would still likley use gramaxone.
We have noticed in the past that roundup will not touch the pigweed.
I want/need a CLEAN dove field. What would you arm chair QBs do at this point?
