Spring barley volunteers

[Laggard]

How much Roundup VISTA plus 450g/l

glyphosate to take out these volunteers please? OSR drilled Saturday 22th August, rained 25th August. How long have I got before OSR emerges? How long between glyphosate and OSR emergence safely?

1 litre would kill those stone dead.

You need to check if the OSR has chitted at all and how far it is from emerging. You may need to wait and use a graminicide instead. Won't be long before all that barley has 2 leaves and you can use falcon etc.

I'd be careful with using glyphosate on that, although glypho is contact only it's been shown in trials to improve the efficiency of pre ems in cereals so must have a mild residual effect hence be careful if the osr has shot, which I assume it has by now.

 

[deleted user 837354]

I have not heard that glyphosate has any residual effect and have used it pre-em many times. But usually only after a day or two. In warm soil and good weather crops can be emerging a lot quicker than you realise so it always pays to dig around and check first.

At the end of the day it may be that those barley volunteers are going to increase in number as more poke through so a go with graminicide may be preferable anyway. There's never any right answer.

I've seen a couple of trials that showed a marked increase in cereal pre em efficiency when glypho is added without any visible weeds.

I think I was once told that t was said glypho had a mild residual effect when it was first launched.
I seem to remember it was something to do with the time between it hitting the ground and being broken down by soil microbes.

But I may be completely wrong and just talking[emoji90]

 

[Laggard]

Thank you for the advice. It does talk of rain here this afternoon so would that be better or worse for the OSR? It’s also completely still here @ the moment

I’d wait for the falcon. So I’d be able too sleep at night.

Yes just wait to put a graminicide on, what’s the point in risking it.

 

[Chae1]

Forage rape been through in 2-3 days last few weeks. I wouldn't risk it

 

[Laggard]

Ok I’m not going to spray glyphosate. Which graminicide is best on spring barley?

More likely there are tiny weed shoots, just very difficult to spot.

Aramo/Falcon/Fusilade will all do the job.

Fusillade is probably the fastest acting and dearest. Co pilot and falcon will both do the job perfectly and cheaper. They will stop any further growth once applied but may take 2-3 weeks for total kill. I have Clayton sachmo in stock ready to take winter barley out. Agronomist reckons on 0.5- 0.75l/ha but I shall wait and see nearer the time to decide. FYI.I have taken barley out of a sugar beet crop on several occasions with co pilot at a eighth of the recommended rate. Timing and application conditions need to be ideal though for it to work. If you are trying to remove blackgrass too there is centurion max but I’m not familiar with its use.

If you want to learn more about agronomy and chemicals i can recommend joining NiabTag.

The vanilla fops and dims are the first place to go. I can't remember the rate but if you catch the volunteers at 2-3 leaves you can do it at a reduced rate. Adjuvants (I think I used to use biopower or LI700, again can't remember, torpedo or drill probably just as good) helps speed the kill up but they stop growing near immediately anyway.

Why don't you go back to agronomy?

There's a lack of young enthusiastic individuals like yourself in industry

As much as I enjoy it, it all revolves around selling stuff. People have said 'ahhh, you should be a vet' which is kind of logical given my experience with animals but again, it revolves around selling stuff. 5 years of cold calling is enough to tell you if a job is suited to you or not and the selling part of it is central to it, it never goes away. Even when you are 50 or 60 you are still having to think about the fact that your customers might retire, pass away or sell up. I had a very specific niche working in this area which I enjoyed a lot, but I didn't see it going anywhere beyond where it was. Other people have taken on those shoes now and maybe they will be better or more successful than me. I believe I gave it a fair go, I learned a lot from it too and you won't find a better employer anywhere I know that, but it becomes a stress, grief, life vs reward question. Probably I made it harder on me than it needed to be, I never ever turned off my phone. Clients would ring or text or email virtually around the clock 7 days a week. I rarely did holidays, even when I was away I always took my bag and laptop! Agronomy can become all consuming. Some days I would be driving around thinking it was the best job in the world, and in many ways it is. Other times things aren't going as well, you've lost a quote or a client or a crop is looking less than perfection (I became quite a perfectionist which is absurd in agronomy) and it would put me in a mental downer all day. It's quite a lonely world as well if we are honest.

Going to spray the volunteers with 0.75l/ha Falcon (propaquizafop). Is it worth putting any nutrients in for the small (first true leaf) OSR?

 

[robbie]

If its mn prone ground then yes chuck a couple of lts/ha in itll cost under a quid and if it doesnt do any good it wont do any harm.

Itll help as a adjuvant with the falcon aswell.
