How to control dandelions?

[grassfarmer]

Got corn stubble that we will be seeding back to corn. There is a dandelion about every foot across the field but they make up about 90% of the weeds - very little else showing. Any suggestions what to spray that with - getting conflicting advice on whether 2,4D is wise to use pre-seeding or immediately post seeding with corn?

Grassy, if corn can tolerate clopyralid and MCPA residue in Curtail M that would set them on their ass.

Anyone else?

Grassy have a look at Sortan IS from Dupont.



I think that would work very well

How about a high rate of roundup and express

Express is very good on fandelions with a full liter of roundup

This fall if you have time..post harvest gets them all...

thanks klause , can tell I've never grown corn !

Thanks folks. Klause do you know Sortan IS works on dandelions as I've read all the literature on it and nowhere does it mention dandelion. I did find this precaution in the small print: "CAUTION: Do not graze the treated crop or cut for hay; sufficient data are not available to support such use."

Partners we graze the corn in winter so fall control isn't really an option.
