Spraying herbicide.

Hi! Two dumbells here! Father and son team thinking of planting silage corn. Just wondering how much 2,4,D to use per acre. Trying to figure costs etc. before jumping in to this. Been doing hay for a few years, now expanindg into beefers, and pigs.Hey, someone has to take the plunge! Or where is our food gonna come from? LOL Thanks in advance guys... Darryl

I'd start by reading the label. 2,4-D on emerged corn is a tricky business. You can mess with the growing point and make the stalk extremely brittle. Your better bet would be to buy some Rounduo ready corn. Generic Roundup can be bought fairly cheap and doesn't need any licensing to buy. Ideally you'd put down something pre emerge like Harness Extra, or Dual and come back if needed with a post treatment for any escape broadleaf plants. If you have a local Coop or agronomy store where you'd buy seed, fertilizer, etc. They will have a good plan for weed control in your area and tell you what licensing you need to have to buy and apply.

Another person not answering your question, but some version of dicamba can be a much better choice for about the same money. Banval, Clarity, and many others, it is off patent now so many are making it.

I really like Status, it is a granular, it has safeners in it so you can spray it on taller corn. Really gets the broadleaves.

As for 2,4D, it seems less effective any more. Depends on if you are talking the ester or amine, and what formulation. Hard to give an exact answer without knowing what brand of the stuff you are going to use.

In general I got nervious at a pint an acre but it didn't kill so well at 1/2 pint, and the corn can't be more than the 5th leaf showing or you will hurt the corn.

No till or minimum till? how clean are your fields now? 2-4-D alone never did the whole job for me post emergence and you have to get on it when the corn is 4-6 inches tall unless you have drop nozzles, even then I would not do it in my area due to the high average temperature. I have way better luck for silage corn with RR variety and spray round up one time at 12 inches tall, thats after no till in ryegrass/clover stubble with no pre-plant applications. 3 trips across the field and the 3rd one is with the chopper.

You could just go with Roundup Ready and spray one quart of Roundup per acre. No need for the 2,4d if you do that.

If you are planning on planting a conventional corn hy. (a non GMO hybrid) try a brown mid-rib silage hy. makes a sweeter more digestable silage, & good ear corn for hogs too.. You'll probably need a grass killer along with the (dicamba) 2-4-d, Banvel etc. Try Accent , worked good on postemerge foxtail etc. for me...no carry over like attrazine based herbicide's.......

2 4d is not that big of deal poasting over the top if the corn is 2ft tall or bigger put on drops to keep it out of the whirl lv 6 is around 28.00 dollars a gallon and run about 6 oz to the acre depending on weed size and run 15 gallon to the acre on water you will have great kill any question give me a call 1 618 926 1286.

Need to add a residual to a Roundup Ready system to get the best weed control. Spranying only Glyphosate is the reason we are now fighting resistant Palmer Amaranth, Marestail, and other weeds.

rrlund · Mar 4, 2013

Ya I know. I use Prowl and Atrazine pre emerge and seldom even have to clean up with Roundup,but if it's this guy's first time,it's best to make it simple.

Go to your local fertilizer service/co-op and talk to them. The manager there will set down with you and help come up with a plan and give you estimated costs. If you don"t already have a fertilizer service that you go through for your hay, then you definately want to get in touch with one. They offer services that a corn farmer can"t do without, such as soil sampling, custom fertilizer/spraying, and good agronomic advice. Not sure how many acres you"re thinking, but even 20 corn acres adds up to a decent amount of inputs, and they probably don"t get many "new" customers, so they should be interested in your business and give you good service.

Darryl 2Ms · Mar 5, 2013

thanks! sounds like good advice. just looking to get our feet wet this year. maybe 5-10 acres. Have to try. If us New guys don't who will? lol

Darryl 2Ms · Mar 5, 2013

thanks Karl. I always get good input from everyone here on YT. thanks again

Darryl 2Ms · Mar 5, 2013

thanks for your input. I was thinking of a sweet corn or anything that is a small round kernel, because I'm planting with a grain drill! Oh no! I got mixed feedback on THAT here on YT. But thats all I have for this year... An old I/H Mcormick 7x13. And they recommend a small round seed kernel for silage cor. This is all new to me but I gotta try!Buying feed is getting expensive and I have a hammermill soooo....

Darryl 2Ms · Mar 5, 2013

sounds good. I had just figured 2,4,d because it's cheap. Guess I have to talk to my extension agent. It's confusing at first with so many chemical choices, but we'll figure it out. Hope it's not too late in the season...

Darryl 2Ms · Mar 5, 2013

thanks Jim. I see i have more research to do. Don't want to contribute to weeds getting more resistant to herbicides. Time for my local agent i guess thanks

Darryl 2Ms · Mar 5, 2013

sounds like roundup is the way to go. I'l be plowing up a small section of an established hayfield. So it's plow, disc, rockpick, springtooth harrow, plant, spray, then chop. I know too many trips. Luckily I have small fuel-efficent tractors. Can't figure for our time though. we almost work for free lol

Darryl 2Ms · Mar 5, 2013

I was thinking 2,4,d because it's cheap. And actually I was thinking of a PRE-EMERGE herbicide. I don't know if 2,4, d is what i'm looking for. I guess I'm showing what an idiot virgin I am! lol But we all have to try new things, and live and learn...

Anonymous-0 · Mar 5, 2013

Thanks AAron. Looks like roundup is the way to go. time for the extension agent too. thanks for the names of the PRE-emerge herbicides. thats more along the lines of what i was thinking. You can tell I'm new to this. Thanks to all you guys who responded.Too bad the whole country isn't like country folks...

One year we were seeding sudax with the drill and ran short on seed, but had some old seed corn sitting around- ran it through fine and it grew. I can't say what percentage didn't grow from bad placement or poor seed to soil contact, but it can be done. The biggest deal is your seed depth and spacing will be very inconsistent. How will you spray without rows, or are you planning on covering up most of the holes in the drill so that it only seeds every 30 or 36 inches?

paul · Mar 6, 2013

Wait 7 days if spraying pre-plant. Hope you don't get a rain if you go pre emerge. 2,4-D is actually tough on corn, I spot sprayed one year and when I combined those were the spots that were all lodges down. The 5th leaf musta been too far out. You don't want 2,4-D near the growing point of corn, with at sprouting or as it comes above the surface.

An odd deal between corn and 2,4-D, small window to work with.

What exactly do you call or consider a beefer.?? just weaned , cow calf operation , backgrounding or finishing??

Darryl 2Ms · Mar 7, 2013

Beefers can be anything. Bottle babies, or just weaned. Then raising them till they are about 18 months old. Some for our consumption, and some for sale at auction. Anything to make a few bucks and have cheap beef for ourselves. Some cuts in the supermarket go for $10.00 a pound . We do our own butchering. So we save quite a bit. Plus no hormones etc. Still a newbie though!

Darryl 2Ms · Mar 7, 2013

I have an I/H Model MF grain drill. from the mid 1950's. The seeding chart, and the manuals SAY it will do silage corn. There are reducers for certain kinds of seed that fit into "SLOTS" where the seed goes out. Also the drill came with block -off plates for the seed box and the fertilizer box. Since it's a 7x13 drill i can block off some rows and have it plant 4 rows... 28 inches apart. I can also regulate the seeding rate somewhat, and supposedly the reducers help with that. I know it's not as good as a planter, but it's all I have. Hope to pull a heavy roller or a culti-packer behind it to help with soil contact. Here's hoping... fingers crossed

Darryl 2Ms · Mar 7, 2013

thanks Paul. I see I have lot's to learn. But from what I learn here on YT, and talking to neighbors, I'll get through it. Won't be high yield at first, but we'll get better. thanks!
