Kinda forgot that your corn is sweet corn and not field corn. Round up might kill it. I use round-up in my corn but its round-up ready seed.
Hopefully your not out spraying yet

I use a hoe/pulling until the plants get tall or leafed out enough to shade the weeds. Lamb"s quarter, in moderate amounts, is supposed to be beneficial to corn. Some weeds, supposedly, pull nutrients from deeper in the soil. I mulch a lot of my garden with straw or leaves. Mulching helps retain moisture and discourage some insects. I have not seen one potato bug this year. I don"t know why or take any credit for doing anything special. I did plant eggplant as a lure crop, but it looks like I may end up harvesting a few fruits because they haven"t been attacked either.

Impact is labeled for sweet corn and works good on 2-3 inch grass and broadleaves and has a residual.

Geese, YUP! they only eat the weeds. Lettuce farmers in Central Cal have been using them for years now to weed the lettuce patches.

Me I either let them grow or let my geese have at them. But I also do 110% organic in the garden so no sprays or other such stuff for me

Ric1,
I grow about 3-1/2 acres of sweet corn, in one acre patches, each year to sell on our vegetable stand. I use sprays to hold the weed back until it canopies. I usually plant and then spray the next morning so the seed has not sprouted yet. Once the corn has canopied I use a hand held weed wick filled with round-up and 2-4d it will knock down lambs quarter, birddock, jimson and velvet leaf. Look up weed wick or Rodgers Sales Co. on the web they sell a kit but you can find all the parts to make one yourself at a good hardware store. i used to cultivate with a tiller but this seems to work well. I can use it around all our vegstable and only do a little cultivating.

After planting, sprayed mine with atrazine, no weed problems. You have to spray atrazine post or pre-emerge, but can't wait till the corn/weeds are more than a couple of inches tall. I found best to spray pre-emerge. I got real tired of hoeing and pulling weeds, that's why I started using atrazine. This is just in my garden sweet corn. Have 7 rows about 50' long planted at various times. Picked about 40 ears today.

Atrozene,do not use round up or 2-4-d. and you must have a chemical license. to use or buy this chemical. I raise sweet corn myself.

I like to be able to tell the people I sell produce to that it hasn't had any spray on it, and they seem to appreciate it. I use the cultivators under my Cub, and they seem to keep weeds to a minimum. I still use conventional fertilizer because I don't have the volume of manure available to be TOTALLY organic.
Pic is of my garden last year. Only about a quarter acre of corn then.
This year, I have an acre of corn in, and about 3 total acres in cultivation in various veggies.

If you want to chem-farm, Harness pre-plant to get the grass then a hand sprayer with 2-4D to get the broadleaves when the corn is 3-4 feet tall. Otherwise timely cultivation.

I used Duall for grass, 2-4-D for broad leaf but use drop nozzels on your sprayer or hand spray at the base of the plant. I also used the cultivator. Roundup will kill sweet corn unless its roundup-ready which I don't think they sell it yet. DoubleR
If you use herbicides, there are a few things to understand.
Some herbicides are real good at killing grassy weeds.
Some herbicides are real good at killing broadleaf weeds.
You typically need 2 different chrmicals, or one that is premixed together.
Some of the chemicals mentioned need to be sprayed before the corn comes up! And probably stired into the soil.
Some needs to be sprayed before the corn is 5 inches tall or so - while the corn's growing point is still below the ground; or else need to be sprayed carefully down low on the plant stalk, _not_ in the leaf whorls. These chemicals are the most common, but timing is everything. Wait too late and they will kill the corn as dead as they kill the weeds. Got to spray early with these.
A very few can be sprayed on taller corn.
Roundup kills most green things it touches; but it has no effect on the soil or long-term effects, does not kill seeds, etc. So if you use it on non-roundup ready corn, you need to wipe or spray the weeds only, without touching ant green corn plant with the spray. It's great for cleaning up bad patches of difficult weeds or out along the edges; but not really possible to use through the field. I don't think they have any roundup ready sweetcorn?
Anyhow, you have lots of good chemical suggestions here, but just be aware that it can be more complicated, and several of the things mentioned needed to be used long before you planted the corn, certainly not now any more.

I have used Harness Xtra or Degree Xtra with atrizine at full rate plus a bit. If you need a second application you can use Callisto with a touch of atrizine, crop oil, and liquid nitrogen. The callisto mixture should really be applied with a hand sprayer since it may burn the corn a bit but it will ZAP just about any weed.
It seems to hold it until canopy unless you get a washing rain that washes the chemical away. Pre-emergent chemicals are most effective on tilled soil.
I apply mine after planing before any weeds emerge. There will likley be no need for any other application unless that huge washing rain gets you.
I think the real key is to go ahead and chop the stalks, disk them in and replant a cover crop such as RR beans when the corn is done. If you can keep those weeds from going to seed it makes it a bit easier every year.

Ben,
Do you have 40 acres and only grow in the middle of so your neighbors spray doesn't drift onto your food plot? That is the problem with organic you can't control the area around you so you need a buffer zone.

I am like you. I don't like to eat something that has been poisoned by herbicides.
Buctril or 2-4D will work, but may cause you problems for your other vegetables if they are very close. It has a tendency to get up and move during a heavy fog or if the wind blows even after application.
Your safer bet would be Callisto. It will not get up and move. It only affects what it actually touches in the initial application, however it will be a little more expensive than the 2-4D.
