Redekop Weed Seed Control Unit and blackgrass seed.

[Pilatus]

I apologise for starting yet another thread about the above combine attachment.
Simple question , as blackgrass seed is “so small” , is it nearly impossible for the Redekop Weed Seed Co Unit to “mill” the blackgrass seed to powder to stop it germinating?
I believe the Redekop Weed Seed control Unit was designed for milling ryegrass weed seed which is a lot larger than “minute” black grass seed, perhaps @ajd132 may wish to comment.

Only gets 5% of blackgrass from our trials, did about 70% on ryegrass and brome.

Thanks,do you think it is because Blackgrass seed is so small?

That's still a lot of ryegrass seed left behind (30%). I guess when used with other cultural control options it helps but did you find it enough? Cost effective?

No, it falls out of the ear before harvest. The first year lots didn’t which gave some hope but it was a strange season.

I don’t have ryegrass, that was results from one of the other combines. I think for ryegrass and brome to take out 70% accumulating over 4-5 years is massive in conjunction with the other methods. Nothing is a silver bullet.

When combineing most blackgrass seeds have shed as stated above

May work with riegrass
