Spring barley BLW control and rates

I'm never keen in spring pre ems because of lack of moisture and when applied in the autumn I find pdm let's several BLWs through, could add picolinafen but that's expensive and a bit pants in my opinion.
Yes that would be my worry, never been a fan of spring pre-Em unless blackgrass is a problem. Can you still get those spitfire type products

It scares me that some people use just a SU on its own year after year also I'm finding I'm having to use more ally/hiatus type SUs in all cereals to tidy up BLWs. In the olden days when I could use ipu/ctu that did for all BLW and the only crop that got an SU was spring barley one in 3 or 4 year in the rotation.

Has anyone got any ideas on a broad spectrum BLW spray for spring barley that avoids SU so rape can be established without worrying about residues.
I've been told to use fluroxpyr and mcpa on mine because I want to establish a herbal ley after.
Are SUs that bad on residues at low rates?
 
I’ve never tried it but someone on here swore by 15g ally, 0.5starane and 0.5mcpa for small weeds

There is not much that will withstand an application of that if the application and timing is spot on. Starane will sort cleavers, the MCPA will do fumitory and the ally will do the rest that would escape the starane/MCPA (i.e speedwells etc.).

I have often used half-ish doses of ALS type products in conjunction with half or reduced rate pixxaro, starane, MCPA or CMPP type stuff. Indeed, half rate ally (or similar) and headland polo as a one shot wonder on spring barley used to work very well if I had a good mess in front of me.

I used to use 1/4 rate ally equivalent on wheat crops if I had established docks from root mass only but it needs to be done in growy conditions. Docks absolutely hate- and are extremely susceptible to- metsulfuron-methyl.

You may some across combined both-barrel products that contain thifensulfuron/metsulfuron/tribenuron in a single can, this has a broader weed spectrum as well but both are ALS actives and will not do all weeds, particularly if you have any SU resistance issues around. Partnering these kinds of products with other chemistry is a good idea where rates are being reduced and you don't want resistance issues occurring.

PDM is not a cure all. The addition of picolinafen broadens it a bit but groundsel will still come through it from memory. The main bonus is not having a carpet of salad on the first dry day in March which gives you more options to wait and see. Things like groundsel are readily done away with using simple (cheap) phenoxies when they are small.

Which phenoxies???? I've always used Thor/taxi which is straight tribenuron for mayweed and groundsel.

The Livestock and Meat Commission (LMC) recently submitted oral evidence to members of the Stormont Agriculture, Environment and Rural Affairs (AERA) committee on the content and potential impact of the Northern Ireland Climate Change Bill (No.2).

This draft legislation was recently introduced to the Northern Ireland Assembly by the Department of Agriculture, Environment and Rural Affairs (DAERA) in conjunction with agriculture minister, Edwin Poots.
