weedkiller for field

[crazycoloured]

I have a 2 acre field sectioned off but the back field i can use in the summer because it gets so overgrown with weeds and fern..is there any type of weedkiller i can put down to get rid of them without killing the grass??..iv looked at barrier h but thats only for ragwort i think? the field is about an acre...

use SBK from the garden centre, and for bracken roll it about julyto bruse it and this will kill it in two years.

I also use SBK, kills everything but grass. It gives instructions about how long to exclude animals after use.

I also have a braken problem on the edge of my paddock as it comes through from NT land next door. I trample on the bracken and bruise it, although ponies have done a good job of stamping on bracken in the autumn so hoping it will not be as bad this year.
