What would kill, and not just annoy, lambsquarter that is poking through beans? There's too much of it to ignore.
These are Enlist beans and are at R2 growth stage. 20" rows and full canopy. We're hearing it's too late to spray Liberty or Enlist.
We do know the lambsquarter is ALS resistant but according to MSU its not resistant to glyphosate or Liberty. I sort of question that and think it might be a bit resistant to glyphosate but that's not what the lab said.

liberty by itself is unlikely to clean up lambsquarter with any size beyond a sprout. That is a weed it is pretty weak on. A high rate of gly or full rate of 2,4-d is probably going to be needed, but just hitting the tops of a tall weed poking out of a canopy probably isn't going to kill them at this point without a lot of carrier and a high rate. |
Lambsquarter in soys--what to spray?
