No-till corn herbicide?

Fordfarmer · Mar 16, 2013

Tried one field (24a.) of no till last year, planning on trying some again this year. Last spring was wet, followed by a dry summer and fall. Low areas were stunted or drowned out, higher area did about the same as the conventionally tilled field across the fence.
But for a herbicide program... my plan is to burn down with Roundup (or generic) 2 weeks or so before planting. I have some RR seed and some conventional. Which would you use on the no-till ground, and why? If conventional, would you use pre-emerge (that's what I've been doing for the most part for the last 7-8 years) or post emerge?
If it makes any difference, my rotation is corn following 3-4 years of hay, then oats with hay underseeded following the corn... I don't do corn on corn.

We plant non gmo corn in conventional tillage. We work the ground then plant. Call the local co-op within a day or two and have them spray the field with a combination of Corvus and Atrazine. Have used this practice for two years and have no weed problems.

Did you do a burn down in the fall? If not, you may want to hit it twice this spring to reduce early competition from the grasses. That's ok because it will take a little longer for notill ground to warm up than conventional. If the grass regrew after the last cutting it should have caught a lot of snow. That should make for a really good corn crop if it decides not to rain any more this year. Be patient, notill works.

Wanted to do a fall burn down, but it was too dry -
grass was pretty much dormant by the time I finished
haying, and there wasn't any regrowth to speak of.

Lexar or Lumax with a lb of At. On fall applied ammonia we use up to 30 units of N to burn down the weeds that are up. Or anywhere from 120 to 150 units before corn is up.

I have used harness/atrazine and glyphosate OR Lexar/touchdown preemergent on no till corn. Lexar is expensive but I have not needed a post emergent followup. You may need a later post emergent application of glyphosate since your coming out of grass.

You have a good plan, it will work. I would plant RR corn. You just have more options and most recent seed development is in RR. Get all the packages you think you can afford. There is numbers now on the different herbicides as to their mode of action. I would use a different one this year than last. Ask your dealer. This way you won't get resistant weeds. Vic
