Linseed flea beetle

[Tractor Boy]

What’s the general consensus? My direct drilled linseed has been in about 14 days and has been coming through the last 4. It’s into wheat trash and only coming in areas where it was drilled into a little moisture at about 18-20mm deep.
What it could really do with is 12mm warm rain but it’s not going to get that and the cotyledons are taking a chewing from flea beetle moving around in the trash.
Question is, I haven’t sprayed insecticides on most of the farm for around 5 years and don’t really want to. Also will they do any good or not even hit the flea beetle under the trash and just kill anything beneficial?
What’s anyone else doing? The last two years my linseed hasn’t been bothered by them.

My linseed is at the same stage, but with, so far, no damage, but how ever I was stood today in a field sown with a cover crop 4 weeks ago, and every single brassica plant in the mix was under pressure from csfb. I know ffb is different from csfb, but is it.
I will avoid spraying, never done it yet in the six years I have been growing linseed.

I lost crop to ffb last year despite land not having had insecticides in years. (and I did spray once). I have had to spray for it the last 3 years. i no longer grow linseed. Unfunnily enough it turns out there's a beet flea beetle and the f**king things are hammering my beet. Can't help you with making the call but i would say there isn't the resistance problems there is with csfb but that's just my opinion.

We’ve lost about 25 - 30 ha to ffb. I’ve never seen so many of them on so many plants. They have done so much damage we have sprayed off and Going to redrill this weekend hopefully.

Why spray off? I just redrilled into the old stuff. Trying to get the beetles to sod off? Redrilling is expensive

There were odd bits of bg and the linseed was good in some areas and none existent in others so I’m hoping to start with a clean slate.

Who's bright idea was it to stop insecticide seed dressings?

The result is flea beetle areas which will likely be bare.

One very small dose on the seed and job done.
Now, indiscriminate sprays.

Progress huh???

We redrilled ours. Very dry on top bit of moisture underneath, jury still out if it was the right descision. Its coming up but needs a good soak of rain and it will be a good plant.

My linseed emerged well but was hit fairly hard by FFB , rightly or wrongly it had 2 insecticides

Rightly.

Looks good now. 1 definitely, 2 possibly.

Apparently they aren't active when the autumn crop is establishing and the crop is well established by the time they are active in spring.

What's black grass control link with W Lin ,,,,,, part of the advantage of spring Lin is the BG cleaning aspect

I think you are limited to crawler, avadex and possibly an EAMU for CMax but not sure about the latter. Problem is that its early drilled in autumn.

We wouldn't be growing Sp Linseed if it weren't for Blackgrass. Its the worst paying crop on the farm. If you cant control the blackgrass there's no point growing it as its only advantage

This is correct, the flax flea beetle only emerge in the spring and spend the winter over-wintering in the soil, and therefore are not seen in the winter crops. I have seen many crops all over the country and never seen flea beetle on winter linseed.

There are; Avadex pre-em granular and liquid form, Centurion max, Crawler and Laser.There are fop and dim herbicides for volunteer cereals as well.
