I've had good control from Broadway Star + non ionic wetter (+ water conditioner if the water is hard). Ryegrass has a waxy leaf, so I wonder if a combined wetter/MSO adjuvant would be better. @Corteva Technical ? Your trade off is crop damage, so don't go overboard on adjuvants.wheat.
I’ve said this before but Ryegrass is worst than Blackgrass and I think will be a much bigger problem for this country. BG can be effectively managed by a mix of cultivation, no till drilling, rotation and chemistry. RG can’t. We’ve got two options for RG and that’s roundup and Defy - see attached.Axial Pro does nothing. Would Pacifica Plus maybe do the job this spring?
Spring crops are ok but you end up glyphosating multiple times which lets face it is bad for the environment and not a long term solution.It's an awful weed. It germinates when it feels like doing so, though stale seedbeds and spring cropping do help, if only by having more time outside a cash crop when you can use glyphosate.
For what it's worth, I've had good control of tested & confirmed RRR black grass with Atlantis applied when the weed was very small as part of an expensive tank mix.
Have you tried rimsulfuron, niceosulfuron or the twin ALS product i.e maize herbicides?I’ve said this before but Ryegrass is worst than Blackgrass and I think will be a much bigger problem for this country.

Ploughing and stale seedbeds don’t work for it and crops like spring barley or rye that smoother ground are less effective also.
The arable weed problems are usually from Italian Ryegrass. Seed breeders of ryegrass may have been unknowingly breeding up resistant types.Non arable farmer reading with interest. It seem the battle with grass family weeds just keeps evolving.
Why has RG become such a problem? What about farmers grown PRG as a rotational crop or are the cultivated varieties killed off more easily?
Interesting. If it was meant as a water conditioner then it’s not much good. AS only helps glyphosate though there may be other benefits.Its normal here in france to use an oil with Pyroxsulame (active in Broadway Star) but many people also add Ammonium Sulphate. Its recommended by Arvalis (sort of French ADAS).
