Thank you very much ! Last spring I used Axial(Pinoxaden) from Syngenta. It worked on emerged wild oat but it didn't work on Apera. Also wild oat 2nd wave emerged late in may. I need a good residual herbicide at least for wild oat.Triallate pre emergence is good on oats. Granules but now available as a liquid as Avadex.
Fenoxaprop and clodinafop will kill wild oats.
Apera is silky bent grass family. Not normally a UK problem, so I'm not sure how to control that. We use more expensive sulphonyl ureas like Atlantis or Hatra (mesosulfuron + iodosulfuron) for blackgrass & I believe the Germans use it for these types of grass weeds.
I cultivate winter wheat in rotation with wosr. Fenoxaprop active also doesn' t work on apera and later wild oat waves. Do you use chlortoluron in UK? Is it effective and safe for winter wheat tolerant varieties? Only options left on our market are iodosulfurone, chlortoluron and the active from Atlantis. What do you recommend?Axial is expensive but the only option on barley crops later in the season. Clodinafop (Topik) is ok up to growth stage 41 flag leaf sheath extending. Winter or spring sown cereals? I doubt you would make a residual last long enough.
Autumn germinating very effective but spring germinating no use depends which species predominates on your landCTU was pretty good but you can only use it on tolerant varieties. Used to help with weed grasses. Wild oats used to emerge much later so I would never rely on it for that alone. Half rate axial will sort them.
