Will 2-4-D Kill Bermuda Grass Seedlings?

[Complete Turf Care]

The following is taken off of a sample label of 2,4-D Amine.

ORNAMENTAL TURF AREAS
Lawns (Residential, Industrial and Institutional), Parks, Cemeteries, Athletic Fields and
Golf Courses (Excluding Grasses Grown for Seed or Sod Farms).
Use 2 to 3.16 pints of product (1.0-1.5 lbs ae) per acre per application for control of annual
broadleaf weeds. Use 3.16 pints of product (1.5 lbs ae) per acre per application for control
of biennial and perennial broadleaf weeds. Treat when weeds are young and actively
growing. Perennial weeds should be near the bud stage, but not flowering at application.
Use sufficient gallonage for thorough and uniform coverage.
SPOT TREATMENT IN ORNAMENTAL TURF AREAS (Parks, Cemeteries, Athletic Fields
and Golf Courses, Turfgrass (excluding sod farms).
To control broadleaf weeds in small areas with a hand sprayer, use 1/4 pint of this product in 3
gallons of water and spray to thoroughly wet all foliage. Do not exceed 4 pints of this product
(2.0 lbs ae) per acre.
USE RESTRICTIONS FOR ORNAMENTAL TURF AREAS
(Golf courses, cemeteries, parks, sports fields, turfgrass, lawns and other grass areas)
Post-emergence:
Do not use on susceptible southern grasses such as St. Augustine.
Do not apply to newly seeded areas until grass is well established.
Bentgrass, clover, legumes and dichondra may be injured by this treatment.
Limited to 2 applications per year.
Maximum of 3.16 pints of product (1.5 lbs ae) per acre per application.
The maximum seasonal rate is 6.25 pints of product (3.0 lbs ae) per acre, excluding spot
treatments.

I would think that cockleburs could be controlled easily with just regular mowing. A couple of years of mowing to keep them from going to seed and your problem would be non-existent. The burrs will always be above your grass so you can just set your mower to mow right above the grass tops to keep the burrs from seeding out.
Many years ago, on the farm, we used to be able to buy 2-4D in a wax bar that we dragged over the tops of crops to kill the weeds but not get anything on the crops. They also have the headers with saturated cloth that do the same thing. You may look into these and see if they are still available rather than spraying. This method only doses the weeds rather than covering everything in the pasture, so it takes much less chemical.

Problems I had with them before I treated such was location among other things....the bull calves sheaths. They love water and love to grow in water ways, sloughs, swampy areas, pond edges and lots of places you can't get to them with a mower.

2-4-D is labeled for use in Bermuda and Bahia pastures. I use it all time. It is my main weed control. Think of it a selective broad leaf herbicide. I've used it in the yard for the little flat stickers. it knocked the centipede back, killing the top growth but the roots made it fine and it recovered fine. I was able to enjoy two summers before the seeds that were left made a comeback this year. Use a surfactant with it and you will like it even more. If the Bermuda can handle bush hogging I would opt for that as well as limeing your fields. weeds cant tolerate the constant mowing, it causes them to use up their root stores because they don't have enough leaves to manufacture food. They love acid soil, grass doesn't. Lime is two tons an acre hear the first time you put it out and one ton per acre every year. its 48.00 a ton with a 6 ton minimum right now to give you an idea, we have a lot of rain fall and really sandy leachy soil. so it don't stick around much hear. As far as the age of the seedlings and when they can be sprayed I haven't learned that yet.

That's the quote I remember seeing.
