Pre-emergent for Corn?

[SplitG2]

Just wondering what you all use for a pre-emergent herbicide for corn?

[dave6x6]

Can't help on this one but i know i'll be taking notes when you get some answers. Was just telling someone about the anxiety i get whenever i spray something. It's stupid but i usually can't sleep for fear that i mis-mixed or grabbed the wrong stuff or did something and just ruined all my hard work and my plot.

Dave, I have only used post emergents but wanted to use a pre-emergent next year. I would love to use atrazine but it's restricted. I'm looking at Surestart, Prowl H20 and Lachlor II.

I don't mean to hijack the thread but imo it's not stupid. I don't look forward to spending a day fixing a plot, did that recently, I hope. Then there was last year - well nevermind.

Corn is an annual yes? From what I read it's a heck of a thing to get rolling. Maybe someday, right now I'm not willing to risk trying it. The thought of 1/2 acre or more of corn on the lease - man, that would be like the cleavage of plot work.

I use atrazine fro preemergance, what little i have left... if the field looks like i'll need it. For the most part rr corn is the way to go most of the time. Corn isn't that hard prep is the same for any plot, the planting all the rows is the problem. it can be broadcast but be careful not to overseed, and disk into ground 1-2in deep max.

This year was my first attempt at a corn plot and it was a huge failure. I disked the soil over and over, spread lime, and had a soil test done. I got rr corn from nwtf and planted it roughly an inch deep on Memorial day weekend and when I got up to my property last weekend I couldnt find a single sprout of corn growing. I have no idea what I did wrong??? I thought that it might of been due to the fact that i sprayed the field with round up just prior to planting but the guy at agway said that it would not of effected the corn. Could I possibly of gotten a bad bag from nwtf? Any thoughts on what I did wrong? The year prior I grew powerplant from whitetail institute in the same field with success so not really sure what could of happened????

Round-up Ready is the only way i've ever done it. Growing the stalks have never been an issue but i've been a bit disappointed in the ear yield though. Thats why i was wondering if using a pre-emerg might help in that reguard.??

I do not use any chemicals a small piece.I just turned the ground over with a shovel cleaned some of the weeds out mixed some dry cow manure in and put the seeds around an inch deep watered them and they are up around 3" now.That was about 2 weeks ago.The farmers fields that they did less than a month ago are up around 1 foot now.

corn needs 150-200lbs of N and needs a clean field bed to produce a good yield.

You just reminded me why i always am reluctant to do corn in our personal plots. They are sweet to have during the season but the initial cost is pretty high especially if your planting 4 or 5 acres. 150-200lbs N means 15 - 20 bags of 20-20-20 per acre at about $19 per bag. Thats $380 per acre. 25 bags if you can only get triple 15. ($500) Ouch. I've always thought corn was too expensive for my blood but maybe there is a more economical way that ya'll can fill me in on.

[SplitG2]

Dave, you would use urea(46-0-0) at $22 a bag so 8 bags would do. To cut down on cost I plant soybeans or winter rye one year and corn the following to get the free N produced by them.

[SplitG2]

I also get my rr corn from NWTF at $10 a bag. Helps cut down seed cost.

How much rain did you get after planting? If you got too much rain it may have drowned the seeds. I had that problem a couple years ago. I planted 2.5 acres and not a stalk grew. The seed rotted in the ground.

I've seen birds raise hell with a corn field too. Especially if it is a smaller field. They were picking the plants as soon as they popped the ground.

You can still get some short season sweet corn and plant it. I'm putting in some 68 day sweet corn tomorrow.

urea, 45-0-0 is the way to go for a better yield apply when a ft high or so, if your plants are purpleish the need potassium as well. as for the field not growing, you may of got a bad bag, check the date on the bag, yoou chapter may of had some leftover from a previous year and gave you that. Did you use the correct plate (if you use them in your planter) a crushed/damaged seed won't grow. Lack of rain after germination will also kill the young just sprouted plant, crows will pull fresh grreminated corn (a lot more than u think possible(i lost my 2nd planting of sweet corn to the bastrds this spring 5-6 pants out of 10 50' rows is whats left.. they pull the sprout and eat the kernal..

Thanks split an g-man for the advice. Just a couple more questions and sorry to get off the pre-emergence topic but hopefully all this info will help everyone interested in getting the most out of their corn planting. It sounds like you can apply the urea at planting but might get better results applying at one foot. ?? I've never had a soil sample that didn't require almost as much P-K as the N so thats why i've usually gone with triple 19 and thats why i haven't used the urea in the past. The purple plants is good info. If i do add the urea at one foot, can you broadcast it or what is the best way to apply it.?? And lastly, have either of you had good luck with just going with 46-0-0 and nothing else either at planting or at one foot.?? Thanks

[SplitG2]

Dave, some put down all the N at planting and some put half the rate at planting and 30 days later put the rest down. Some also don't put anything down at planting and add it later. I have done it all three ways. all good results. corn needs it on the 30 day plus mark. I don't use the luquid, so I top dress it right before a rain. Make sure rain is in the forcast! U don't want to throw your money away. If your soil also needs p and k, I add that when I disc the field.

Spent about 8 hours today getting myself up to speed on corn plantings and found some great web-sites and tutorials from Ohio State Univ and Univ of Missouri. Also spent time speaking with Stanton Ag and got some real world advice from local farmers. Not exactly the way me or my wife expected me to spend one of my vacation days this week. oopps.. What i found was that G-man and Splitg2 could teach at either one of these schools. I don't have to impliment this new knowledge til next year but i'll be ready with a new game plan in 2013. Thanks for the seeds of knowledge.

[G-Man]

I broadcast spread my urea, i have done both adding 12-12-12- or 10-10-10 at time of planting and adding urea later. ON new sod ground, i would spray roundup or like equivilent(there are alot more cheaper knock offs) just check the active ingreedient. and add pure urea later after burn off. LOL thanks for the compliment!
