pgr on stressed crops.

[Chae1]

Agronomist has put out chlormequat 750, and another one canopy to put on spring barley. Now my understanding is the purpose of these is to encourage rooting and more tillers. However the crop has been stressed for the past 4 weeks with low temperatures and high winds. Will the environmental conditions not have had the same affect as the growth regulator will?

chae, we did some of our dd'd spring barley a few weeks back with ccc, and have just followed up with moddus to encourage tillering really, all looks as well as where it went in following plough now. depends how well it looks/ how lush it is i guess? wished id gone with terpal or cerone on some last year as it went down in places dont want the same again!

hope alls well up youre way?

cheers dh.

I would send it back!

Yeah good thanks. Just watching a hale storm out the window just now!

Doesn't look lush at all so not putting it on too keep it standing. But does look thin so anything I could to thicken it up would be welcome.

Chae, have you growth there at the moment? CCC wont work unless you have growth.

I'd agree with your perspective. No point hurting a crop any more than you need to!

Warm days and cold nights can make a PGR really hurt a crop. That said 0.5L/Ha of CCC (enough to tiller spring barley)probably wont hurt a crop unless temps are extreme but there does need to be growth for it to do any good.

Canopy is supposed to be quite crop safe compared to straight Terpal or Moddus.

 

[Chae1]

Very little growth at moment, most of weeds controlled by pre emergence spray so not a big rush. Trace elements would give it a boost though.

 

[spin cycle]

most spray labels advise against using on stressed crops...bit of a disclaimer i know but i'm with iben

 

[Spencer]

I've been wondering the same, but forecast after today is pants til middle next week, so just done 50ha this morning as no pre em and weeds were getting a bit big! It's moving slightly and temps aren't too low with all the rain moving in, needs to tiller more, so hopefully 0.6 of cc 750 will help and not hurt it! Time will tell!

I put on some this week 1l/ha and to be honest it's the only fields that I can visibly see growing but the weather is holding up doing the rest

 

[MF 390T]

I put about 0.25 l/ha Canopy and about 1 l/ha Opteman on the barley on Tuesday the 26th of May. Looking today, I'm well pleased in how they're starting to tiller. At the time I put it on I would have said the crops were mildly stressed but I thought the manganese would do good. This month has been terrible for everything here, hardly any growth what so ever due to the cold and wind. The only thing that would have done well is a wind turbine!
I also would be keen to go out with a low rate CCC to thicken things up a bit more. However could this negatively affect the crop as the Canopy should still be active or would I be better to go out with more Canopy? Any thoughts anyone?

I agree send it back from the info you have given us, you always have the choice of doing something later if it does run,,

Never GReg spring barley(malting) here.

 

[Brisel]

I rarely do my spring barley but gave it 0.5 Terpal + wetter here as it looks pretty lush.

I have done the same on some of mine, and feel I may go again on a few bits where fertility is very high(mixed farms-FYM)

 

[Brisel]

The same as in 0.5 Terpal?

Was talking to our agronomist today, he was saying a lot of spring barley is not tillering purely down to the weather. Thankfully ours is god knows why. We really need some warm weather to get things going before it is too late.

14mm of rain and extremely strong winds here today, probably in the UK now. I've decided to spray a couple of fields of spring barley with Canopy during the week, they are quite lush and today's weather made up my mind.
The second last leaf is nearly out.

Winter oilseed rape got a bit of a tossing too.......at least the price of it took a big jump today.
