Lush spring barley

I don't recall having ever used canopy on spring barley, the use of terpal was always nearly automatic for most people but it is a later on job.

Moddus/3C is an early-on job and no good done later.

Magphos K can be used to pump a bit of foliar potash on but cheaper ways of doing it on larger acreages.

Never put growth reg on spring barley before but did T1’s yesterday & looks like it could do with something.
Very lush & leafy in places. Particularly wheelings, headlands alongside trees, double sown bits etc.
T2 usually goes on at awns peeping to cover ramularia. Should I bring that forward a week and put something like terpal in tank mix with it or does it need something going on before that?

Do it before awns emerge. Pref at flag leaf peeping out. The fungicide can go on at the same time, no good driving through the crop again for the sake of two weeks at most.
 
I don't have my resources to hand. What's the difference between Terpal and Cerone?

I'm going entirely from memory now but terpal and canopy are quite similar, though canopy can be used earlier and works in a few points of the chain,

Cerone is straight (and a lot of) ethephon and just works by taking a cudgel to the crop.

I was always under the impression that in order of harshness (and outright efficacy) to the crop: Canopy<Terpal<----Cerone.

0.5 to 0.7
I’m putting it in on planet as it’s a 4t crop on 3 ton legs
Anytime from 32 to 39
Terpal is one of those PGR that you need a magic ball for, if you firefight just as awns emerge you stop it in its track and head is slow to emerge from leaf sheath and if weather turns wet you can it can damage grains
If you have lush crop with expectation of more rain and rapid growth and variety such laureate I would just do it
We had a dry may but now we have got rain and crops are turning into silage with rapid growth as soil N becomes available

Id agree completely with that comparison. I found Canopy too mild and unpredictable on barley. I like Medax Max on wheat though.
Terpal is the pgr the pgr that I’ve always found does exactly what it says on the tin.
 
Perhaps we should have a PGR ready-reckoner in terms of products, rates and a mention of potentially hot mixtures on crops? My problem is I can't remember the rates any more and what I would consider 'normal' in my region is vastly different from somewhere in the East where you'd need 100 units to get a wheat plant to do so much as move.

What is medax max?

I've also used meteor but can't for the life of me remember how and when to use it.

I think barley is just able to grow through some of these products without penalty. I remember spring barley crop I sprayed with manganese, some zephyr and 0.2 moddus early on and I went back about two weeks later and had a fright because the awns were coming out and it was barely 8 inches tall. It was a very dry hot time and I thought: 'fudge, I better not terpal that' so I sent the T2 straight away and left it alone.

About a month later it was windy and a good rainstorm saw it (and in fairness most barley crops in the area) bashed about and half brackled, bloody stuff was around my waist and going for it prior to that as well.
Barley just must have some slightly different physiology and metabolism to wheat.

Terpal is 30 percent mepiwuat 15 percent ethephon. Cerone is 50 percent ethephon. Canopy is prohexidone calcium plus mepiwuat. I don't believe you can get a straight mepiquat .

I find half a litre of terpal pretty keen. Third of a litre of cerone is enough to halt wheat . You can use terpal as a split dose in barley if it looks like it is going mental.

I agree on canopy being mild, have used it in past and crops went flat.

Here you go http://www.pcs.agriculture.gov.ie/m...s/labels/05507 - Medax Max - 2017 to date.pdf

I do wonder sometimes if the added Moddus to the Canopy to make the Canopy a bit more reliable.

I’ve done harm with most PGR’s at this stage and I prefer to avoid them where possible. Moddus has been the most common offender for me.

Winter crops were very forward here this year and February CCC has been useful to avoid apical dominance getting away too early.

I don't think I ever got near a crop in a February, most years it would to be cold for it to work properly I suspect.

At what stage do you prefer to avoid PGRs, approaching ear emergence? I would tend to avoid it as well. T2 was the latest cut off in my mind.

I agree, getting activity in Feb is rare. But we are in a mild area and it was at the end of the month.
A lot of Septoria (even more than normal) in wheat over here this year. Uneven tillers and the resultant uneven leaf emergence has hampered Septoria control. No curativity over here now I think.

In terms of avoiding pgrs I use them if I think it’s needed but I see some people just lashing them on as blanket treatment - for example Moddus on stiff varieties like Costello. Pgrs have a yield penalty so only use if really needed.
