How soon can you plough/drill winter wheat after glysophating grass ley?

[Farmertom1988]

We've got a 10 year old ley that we just sprayed off with glysophate last Thursday, looking to get it into Winter Wheat but worried we may have left it abit too late.

Would the best thing be to plough it, and immediately combi drill behind the plough? To avoid wire worm, slugs etc?

If it’s a ten year key, I’d have seed treated with Austral plus( if it’s still available ) As for timing, I’d get it done if you can

Ah right i'll have word with the agronomist regarding seed treatment. Does it matter if the grass has only been sprayed off 7 days ago?

You are absolutely at the right timing for drilling wheat. Hopefully the grass will have left the soil in a good state and drilling in any fashion should give a good stand provided you have a good seed bed.
The glyphosate should have done its work provided the ley was not a mass of couch.
I would certainly be tempted to plough and power harrow the crop in with the current weather pattern

What species are in the ley? What dose did you use & what was with it? Perennials e.g. couch, want a bit longer and higher doses but as long as you've used a decent dose in the first place you'll be fine.

I'd say a plough and combi would be ideal in this weather. You'll get some mechanical control of some of the soil pests as well as squishing the earthworms but if you need to get it done, crack on.

Not too sure on the species, they are all perrenials, just long term silage cutter leys bought through ACT. The agronomist told us to do 5 litres a hectare of Glysophate i think, and as far as i am aware it was just straight Glysophate, although my Dad sorted the spraying with the contractor so i'm not too sure.

We took a silage crop off it about 3 weeks ago, so there is a little regrowt, but nothing too much.

On that basis, you'll be fine.

I went against advice last week. Cattle off Monday morning, sprayed dinnertime, mucked in afternoon, ploughed Tuesday, drilled Wednesday, sh!tload of rain Thursday. Bit sad looking now, but tufts of grass equally so. We'll see.

I always find killing off after cutting tricky. Needs quite a bit of 'dead time' to green up before spraying. Don't get the same action on weeds. If you can be confident on weather/contractors pre-cutting roundup can do a better job and save a lot of days.

Can always include round up in pre emerge spray if you can get it on quick enough. To kill any grass left on top.

We couldn't travel as too wet after it was sown, so a fair bit of grass on top.

True, but you could ignite a label compliance spat on here by suggesting it. I do also wonder if the highly stressed tufts sticking up would take it in.

I always said 3 days after spraying before applying muck. Ideally a week though before touching it.

Isn't the grass that will be the issue- it will be any couch or perennial weeds that don't die and couch in cereals can be a major pain in the chough.
