Barley volunteers in turnips

[neilo]

Heavy rain after WB harvest meant every shed grain has chitted before the hundreds of marauding geese hoovered it up.

I normally spray them out with Falcon/Shogun (propaquizafop) if there are a lot, as most do.

What’s the lowest rate you can get away with?

Just trying to work out if I need another can to only use a bit of it.

0.5 should be fine. Agronomist was saying the other day he used to use 0.35 in good growing conditions, but that was a bit skinny.

We’ve always gone at 0.3 but was advised the other day that 0.25 would be grand ? rightly or wrongly

 

[deleted user 837354]

All depends on the size of the volunteers you are looking at. I seem to remember doing 0.3L and a bit of adjuvant (can't remember which mind) when they were 2-3 leaves.

Higher rates v’s lower rates........have more adjuvant in which speeds up the signs of kill.
Start at 0.25 l/ha for 2 leaf and increase by 0.1 l/ha for each additional leaf. Or there abouts.

Just done mine at .5 Neil

This is a very good calculation.
I go at about 0.3 for 2 leaves and increase accordingly as the barley tillers. Strong Well tillered barley plants will need a very robust rate.
Adjuvants are your friends, chuck in as much as you can.

Thanks all. At 0.3L I have enough chem already, at 0.5 I don't. I'll give it a go asap.

If too low a rate, will it leave the volunteers unscathed, or would it kick them enough to stunt them? Not to bothered about them being there in a grazing crop, just don't want them swamping the turnips.

 

[limestone brash]

I put 0.75 on in the hope of killing ryegrass
I have also found higher rates to be a lot quicker
Have done barley volunteers at 0.2 but took about a month to work

0.25 will do the job slowly but not 100% unless all conditions are in your favour. That rate used to sort them in sugar beet though. It was co pilot brand then which was an eigth of the recommended rate. Just done 0.5 of propiquizafop on barley in osr on Tuesday for the same reason. Barley shrinking back by the day now. At least you will know next year how low you can go?

 

[neilo]

Done this morning at 0.3, plus the same of adjuvant. All small volunteers yet, so we’ll see how the trial goes.

Should be fine if the weeds are small. Its when they are tillered out monsters you need the higher rates. I seem to remember using it with drill but dont take my word for it.

I use 0.1 Kantor & 0.3 Falcon @100L/Ha water
Never had great success at low rates until I used adjuvant

 

[Flat 10]

I use 0.5 with adjuvant and insecticide and manganese so well wetted and wouldn't go any lower on 2 leaf stuff. Very slow to work when the struggling osr needs all the help it can get.

Have some old galera also quaver flo . It was bought for oil seed rape 10 years ago. It won’t harm turnips ? Have a lot of barley vol I know will swamp them if I leave them. Chem being old doesn’t bother me tbf

 

[Flat 10]

Use a fop, off the top of my head those aren’t. Falcon is/was the cheapest.

 

[deleted user 837354]

Galera was a BLW herbicide wasn't it?

 

[RAF]

Yes I think it is . If anyone wants enough for 80 acres it’s free to a good home

 

[David.]

Any PQF will do Falcon, Raptor etc.
I tend to put 0.5 on if there is a decent growth, and nail it dead, 0.3 is enough apparently but I cba to go twice.
