PGRs on spring barley

[Brisel]

I know most spring barley isn't anywhere near needing PGR yet but this discussion point has come up in my malting barley group.

What PGRs are TFFrs using & why? What are your ideas behind using them? Spring malting barley shouldn't fall over unless seed rates are excessive. Is it for tillering? Would a bit more seed not do the same thing? There is a discussion on rolling to promote tillering going in here too.

Discuss.

We sometimes use trepal for brackling and pgr

 

[CORK]

early (pre stem extension) pgr will promote and maintain tiller production. Later pgr will shorten and stiffen straw.

trials have shown that you need over 300 plants/m2 for maximum barley yield. Plants can only fill a given number of tillers therefore you really need this amount of plants.

i would only apply early pgr if my plant numbers are too low (pest attack etc). Early pgr would be 0.5l/ha ccc.

late pgr would be terpal and only if its looking dodgy in terms of lodging. Be very careful as Terpal can increase screenings.

I've occasionally use Terpal on Spring Barley being pushed for the high N market.If I have to use it,I consider it to be a failure of my crop management..

We used it last year for first time, new agronomist. It's a good idea as I generally feel our spring barley crops are thin. Wasn't convinced on how it worked last year. One field it definitely did, crop was really thick but barley was just small shite that was no use for malting which it was grown for due to high screenings. Grow 130 acres of propino for feed going to push it this year and give it 120 units N and go for @CORK yields. It will get proper pgr treatment.

 

[Sandy]

We always put it on with the first spray but we've changed agronomist and he's not too keen so will wait and see how it looks in a month or so

 

[CORK]

I've asked BASF about the validity of putting CCC on a young spring barley crop to increase tillers. It has quite a visible effect in terms of tillering.

BASF tell me it doesn't increase yield unless the crop was too thin in the first place.


We will start sowing spring barley this afternoon. Paustian and a bit of Propino. 11.5 st/acre for Paustian and 11.75st/acre for Propino. Aiming to establish 330 plants/m2. Nice mix of Imperial and Metric there!

I have never done it @Brisel but wondering if 0.1 Moddus might help stimulate rooting and tillering. Have some bits that are thinner than I would like this year. Probably will try rolling first as in other thread though. Have used Moddus on spring wheat before but mainly because I was worried about lodging.

 

[Brisel]

Thank you for all the replies so far. I was thinking of Moddus but this could be harsh on the crop at T1 in May in hot weather. Perhaps some trials might be in order with 3C, Moddus, Terpal and a combination of Moddus/3C.

I'm not too keen on excessive rolling as I don't have LGP tyres for the tractor, only 650s on a 115hp Case MXU.

 

[T Hectares]

Late Terpal here, sometimes roll if on puffy soil too.
VRA seed definitely helps lodging I feel, high N going for feed or malting if grain N diluted enough and premium worth it !

At what stage are people rolling thin stands of spring barley? We have some fields thinner than we'd like but mainly due to staggered germination from dry weather since drilling mid march. Most plants now 2-3 leaf.

Did anyone try the modus on spring barley? Looking for a strong pgr program this year as anything that comes near 3 ton seems to go flat with me.

I've used it on lush spring barley. None of that this year!

0.1 maximum and little else in the tank mix as it's fairly hot on the crop.

 

[teslacoils]

Roll. Roll again. Roll.

If it looks good, terpal.

What about ccc and canopy I see they both have s barley on the label or are they too hard on it?

Canopy isn't much use in my experience. definitely not hard on it. Not hard enough.

I think using something to hold it back wouldn't be a bad idea this season.

It's going to come through ground and rush through growth stages to produce a head and forget to tiller.

Your thinking ccc at tillering for that?

It's more than the barley just seems to shrug it off! Cos it's warm when growing, unlike winter barley that you can bosh with moddus early and turn it into a little bush.

An method I did consider was repeated, low doses of pgr, but for me spring barley needs growing cheap. Dad like rolling, so that's our main weapon, followed by robust terpal as required. I only want to go through twice with the sprayer really - manganese, blw and potentially mildew first, then robust fungicide.

 

[Chae1]

Will have a chat with agronomist about it. It is something we are considering.

Do you think it's a bad idea?

The first drilled stuff seems to be tillering fine at the moment.

Was up to 300kg/ha seedrate with last drilled.. So shouldn't require much tillering.

My agronomist is a fan of it. I used Selon last year at tillering can’t remember the rate. I did turn the sprayer off for a bit in the middle of the field and couldn’t see any difference but it did yield well in the end. I would like to try rolling this year to see how it goes.
