Variable germination on some of these grass seed mixes

[MrNoo]

Anyone else seen this or suspected? Fields, here, same soil type, same establishment method, drilled the same day, two utterly fine, carpet of grass and two others not a bade of grass to be seen, even on the overlaps on the headland, previous crop was SB and no pre em applied. Stale seedbed, sprayed with Glypho 1.5lt/ha and drilled a week later. I have asked for a germ test for the grass involved and having spoken to my agronomist he has customers that have found the same.
Is there an industry standard? I am aware that last years grass seed harvest was dire. Just interested in other peoples views.
Just frustrating as seems so inconsistent.
This is with an AB8 mix

It won't be germination , all seed sold is tested for germination by law
I've seen slugs take out grass seed also drilling to deep and a host of other things

I would say complete failures, especially of mixtures, are extremely unlikely. If the seed had something happen to it that would affect the germ, you would definitely know before you had even put it in the drill.

Dig the seed up and see if it is germinating, been eaten or what is going on? What stage is the grass at in the two that have emerged?

Slugs are endemic in some fields this spring. I fear I will be re-drilling some winter bird food plots soon due to them.

Flowers have come up!

If it's a mix then a total field failure would mean every variety in the bag failed at the same time. There will be another issue.

I have a 6m strip in a 60ac field without a single plant on it - was where dad ran the last wheat out of the drill in autumn. Not a bloody plant.

Find grass and these other small seed mixes very delicate to things like spring SUs, or spring barley with a pre em.

I’ve put pellets on maize this year. Never done that before.

slug have been a big problem in some fields and some parts of fields
timeing of drilling and following rain seed bed consolidation previous crop /cover
amount of green(other slug food) at drilling all affect slug damage

I've been over fields at night to check for slugs ,one grass reseed was more or less a complete fail last autumn although it had slug pellets at seeding , on night inspection there were places you could hardly put your foot down without treading on a slug

We have same problem, thought it was germination but sadly on very close inspection, seed has germinated then died through lack of moisture !
Very fine shallow seed bed, just not had the rain at the right time !
