Re: Alfalfa Ground
I deal with wild carrot every year myself. It's a survivor especially when you take out grasses or legume sod: carrot then takes over.

Re: Alfalfa Ground
What should the interval be between the last 2,4-D & dicamba application to winter wheat seeding? I was going to use both those products on my final burndown before no-tilling winter wheat here in a couple weeks.

Re: Alfalfa Ground
I have a number of these large (up to 5 foot) broad leaf volunteers. I'm not sure where they are coming from, perhaps from fox feces.
Without chemical application this plant can be cut/wacked fairly high and it will cease to thrive.
2-3 weeks:
~4-5 days:
This is cut/wacked and sprayed with chemical per instruction:
This is cut/wacked presumably only after spraying ~4-5 days out.
Plants which grow from the ground up may no longer stand straight. Starts to look like Bermuda grass. Otherwise these plants are not nearly as effected.
Grasses obviously will not be effected by mowing or bush-hogging other than becoming shorter. Otherwise these herbicides do not appear to be effective at all. They actually appear to increase the difficulty of the situation.

Re: Alfalfa Ground
I would guess a week or two...about the same time as corn/bean.
Alfalfa is not going to be very competitive... So I'm more inclined to go with the listed higher rate, like 1.5l or rd up banvel.. WorSt case you could apply 24d or. Estaprop w no loss in the spring. Dicamba is registered for spring but crop safety is not perfect at all.
The link I put in shows 5-6% loss for 24d. At 7/bu locally and 75-90bpa possible I just can't use it to get rid of clover/alfalfa.
Besides, 2 years is plenty time to get the alfalfa and fall application after heavy rains is ideal
