Blackgrass in spring barley

[turbo]

Is there any chem that can take out blackgrass out in spring barley.

Axial at 0.6l/ha and Adigor at 1.25l/ha. Needs to be done before blw application and black grass past 3 leaves for best results.

Pre em:
Liberator or Crystal at half rate SOLA
Defy SOLA
Stomp SOLA
Avadex
Roundup!
Ploughing!

Post em:
Axial at full rate & early on. Use Adigor adjuvant - it's more expensive than normal methylated seed oil but Syngenta (unsuprisingly) claim that Adigor has the edge.

Does CTU/DFF only have a pre em sola or post em too?

It's a pain. The one year you think that we Willgive bg a headache and it all grows in the spring!!!!

I have put axial on 2 weeks ago at 0.6lha with mixed results

Did you use an adjuvant with it or just put it on straight. Also is your BG susceptible?

 

[Brisel]

My BG at my previous farm tested as fully cross-resistant to all ACCase herbicides including Axial, despite having never used it.

Not joking there. BG is the number 1 threat to profitable farming here.

Yes used adigor.

The one big difference I have noticed is where I used the seed Hal and did not roll afterwards there is very little disturbance therefore little if no blackgrass. Whereas where I used my Claydon and rolled it has tickled the whole surface and germinated the bg really well.

Both, but read the document for rates pre & post em.

Thanks. Are most current spring barley varieties tolerant? A list for next year might be handy. Ta

Have a trawl around the MAUK website for lists of tolerant varieties. If you go to the product pages there should be a link to variety lists.
