Grass weed control in oats

Just wondering what the greater group use in this battle,very limited options here in nz and just thinking there might be some old chemistry out there that might still be available over here,no blackgrass to worry about but mainly concerned with poa and ryegrasses,thoughts anyone?

Is trifluralin still available out there? It's not great but it does add a fair bit of grass weed control. Linuron, flupysulfuron.

I miss treflan. I'm sure it was nearly as good as PDM and cheaper as I recall. If I could have that and IPU back I would be very happy.
 
thanks for that ,we are going to do a small trial with linuron but the interesting one is sempra which is available over here and is used to control nutsedge in maize mainly in the north island,interestingly its also used to kill native grasses in seed turf grass crops.does anyone know if it will control ryegrasses and if so when is the application window,im presuming its a purely contact killer and needs to go on early tillering ?
Dff has been tried before and with some control but unfotunately lexus isnt available.
Cheers

Sempra is diflufenican over here. The earlier it is applied, the better it works. Grass weed activity isn't great but it helps other residuals like flufenacet. It is really designed for broad leafed weeds like cleavers, chickweed, speedwells and brassicas.
 
Thanks guys and again the pit fall of same common names of product rears its head,cheers brisel as sempra here is a halsulfuron methyl -thought it strange that no one else had given it a go!
Been consulting our chem company gurus for bayer ,basf and nufarm and all say that flufenacet is a no goer because of different soil types and climatic conditions,trials have been done and in some years have worked but in others it hasn't and so isnt worth the risk due to crop damage.
Even diuron has been mentioned as its used on oats in oz but over here again crop damage is the reason for not using it
Looks like apart from dff we are up the creek without a paddle,but today some research into flurtamone will be on the cards,never say die!
