What’s best to kill grass in non gmo corn
Accent Q is really the only OK option.
The proper way to control it is pre-emerge with a FULL RATE of a group 15 and then crop canopy.
1oz impact, minimum 1/2# atrazine, and mso
We use Accent Q postemerge if the grass is already there.
To clarify, Accent Q is what you need. The old Accent was hard on corn. Accent Q has a safener in it.
That’s going to be your best bet.
It’s not the perfect option but I have seen topramazone or tembotrione spiked with atrazine & oil work in corn that was in earlier crop stag...More
Accent with out a doubt
