DD wheat post OSR

[Breakthru]

If chopping the straw you mix what I sell with the pre-harvest glyphosate you won't see many slugs. I do the same with wheat where straw chopped. Mix of sulphates and while levels of metals low wouldn't feed the straw. WB needs to sprayed before ear emergence for that reason.

I would agree the bigger the volunteer OSR crop the less slug damage there is. We catch crop after OSR and this gives a good plant coverage of the field. Other good thing to do is watch pre-em herbicides, get the crop up and away

On heavy land
Drill the wheat into the osr on the green the more rape the better
but must be early last week of September
spray off rape a week after drilling

never had it fail the slugs have plenty of rape to eat and the wheat is tillering befor the rape has died

Only ever lost wheat after rape when it is ploughed

now had no rape for 2 years due to flea beetle

will be back into rape i am currently surveying all the rape fields around for flea beetle

Looking to direct drill wheat into OSR stubble on Wednesday with an Avatar (25cm spacing). The fields had SS in July and were lightly moved with a carrier (because I had to to comply with SS rules). The OSR volunteers now completely cover the field and are well established plants. Its light chalky land on the banks but good soil in the valley (based in the SE, Kent). There is also some BG and Ryegrass pressure in places.

I am in a bit of a dilemma about when to spray off and whether or not a pre-em will work because of all the OSR volunteers? Will all the grass weeds be lurking beneath the OSR volunteers, and appear with vengeance when the OSR volunteers die back? I sprayed off one field today but having had a good read on here it looks like I may be better off to wait a week after drilling to spray off the volunteers.

In my experience I would drill on the green and spray your pre-em and roundup mix about 5 days later or 48 hours if feeling nervous.

The drill and subsequent rolling will have bruised the volunteers and exposed what soil you have.

Only thing I'd add to this is wheat can come up quickly in September so be ready to spray it quickly.
Avadex on the drill can be very useful in this situation.

What are people doing regarding the increased slug pressure in this situation? I found with large OSR volunteers, I got stupid amounts of slugs, had sheep in to graze off which helped, but sheep bring their own problems!

I find there’s generally enough OSR leaves to keep any slugs busy until the wheats through then maybe pellet if they start shredding the wheat. Not sure they’d even bother with pellets applied now. Can’t really find slugs in my mat of OSR volunteers which is a bit surprising. I’m fairly Sandy though.
I glypho a week before, not after drilling to avoid buried weeds missing the spray.
I don’t really like preems at the best of times. Peri ems are better as long as there is nothing in there that’s preem only. Gives time for tge rain to wash soil around and shallow seed and let the roots get down a bit out of harms way. I think preems do a lot of damage actually. We didn’t use any in the wet autumn. if 2020 and establishment was noticeably better on cloddy areas. Can’t avoid them if BG though.

The osr keeps the slugs busy for a while, but be ready to pellet once it disappears or they prefer the wheat to shrivelled osr.

But it may be different with your mzuri to a weaving gd.

 

[Matt77]

The year the sheep didn't do a job on the volunteers, the weather turned, I wasn't sharp enough with the pellets, damage done!

 

[britt]

Glyphosate with pre-em a few days after drilling. Physical damage from the drill will knock volunteers back and rolling may be a good idea for this reason also. Slugs will prefer the OSR to the wheat until it dies back, then pellet as they move onto the wheat. If there are a lot of slugs don't be shy with the rate.
Timing is everything with this, so you are very much a hostage to the weather. Get it right, and it works a treat !

Yes on reflection I agree. Asap post drilling this year is quite warm

I find I have absolutely no slug pressure after this but every farm is different. I cannot keep very small slugs away from oilseed rape!

 

[Matt77]

No two years the same either, keeps the job interesting

 

[DrWazzock]

Max glypho rate is 1.5 litres preem according to the label. I find I need 3 litres to kill the kind of rubbish that occurs in my stubbles so it has to go on before drilling. I wouldn’t risk 3 litre preem myself.

With the gd, I've found, to my and everyone else's amazement, that loads of green osr volunteers keeps the slugs happy letting the wheat emerge at least.
Even last year with massive slug pressure it was fine with lots of vols, where there was no vols it was totally different.
They kept at the wheat mercilessly, but lots of pellets later saw it through.
I did however have to pellet some in January as they were besting the wheat then to my surprise.

Those looking to put on glyphosate post drilling…my barley drilled 10 September was up in five days.

Thanks for your replies. I thought I would follow up. I drilled on the green suggested. Sprayed off one field 2 days before and the other 4 days after drilling. Pre-em applied. So far it's looking okay. Bit if slug grazing in one field so applying some pellets tomorrow no slug damage in the other (so far).

 

[britt]

Slugs are absent after rape this year, hardly any grazing so not needed any pellets yet.
There are a few after beans but not enough damage to warrant pellets yet.
