Ally persistence?

[DanniAgro]

Stupidly I mixed some Ally Max in with the weed control of one field destined for OSR this autumn - stupid because the normal method I use for planting rape is scratching and drilling, and the Ally label says you must plough before planting rape in the same year.
Does anyone know if this advice is just being cautious, or you will definitely get bare patches if you don't plough? My soil is clay, if that's relevant.

You'll be fine. Don't worry about it. At the worst there might be a bit less vigour in the osr. Have you sprayed it yet? If not, leave a small strip untreated and remember where it is though you'll have some useful markers! Watch any differences in growth rates and report back to TFF please

 

[DanniAgro]

Phew, you don't know much better your reply makes me feel!
I vaguely remember years ago when the SU sprays first appeared, when there were several stories about patches appearing in fields after use, and my mind was running riot about failed crops etc!
The field has already been sprayed so there's no possibility of control strips.

Metsulfuron is one of the more persistent SUs. I've grown osr direct drilled after Ally before without a problem.

If everyone did that when the label said so, then a lot of direct drillers would not be direct drilling.

That's great, thanks for more help for a worried mind.

I once didn't flush out sprayer properly before spraying kale. The SU left in pipework wiped out 2 lots of kale. After which I gave up as just a small area at gate.

I've seen osr crop write off when DD after late applied ally (later than this) so it can be a problem especially after a dry spring/summer
its fairly rare tho……….
depends on all the obvious factors but it certainly can be a problem

You may get a bit of effect on the overlaps, but the rest should be fine.

I presume that if it says 'must plough' on the label, then that is a legal requirement of using the herbicide. Would that be the case? @Brisel might know.

If it is the case, are some direct drillers or mintillers potentially breaking the law?

 

[Brisel]

Technically, yes.

Not sure what the case is now but in the past labels had a statutory box which was the legal requirement and some advisory information which was just advisory.

 

[Grass And Grain]

That's a worry for most of us if we value our BPS.

Makes one think.

The whole label is statutory now.

 

[Grass And Grain]

Think there are a few herbicides where the label says 'plough before next crop'. Kerb? DFF?

Not even including the DD people, lots of others mintill for rape after cereals or first wheat after rape/beans.

Surprised the DEFRA inspectors haven't picked up on this.

I don't like to even slightly bend the rules when it comes to safeguarding my BPS.

 

[franklin]

The whole label is statutory now.

and I have yet to find a propyzamide label that doesnt say "must" plough to 6" before sowing a cereal.

Interesting Kerb fact of the day (!) if you apply on 1st Feb, it means you cannot plant wheat until 1st September even if you really wanted to drill Claire at 75kg/ha.

 

[DanniAgro]

On the Ally Max label, it says soils "should" be ploughed before planting other crops, so I'm not so worried about compromising my BPS in this case.

 

[DanniAgro]

You may get a bit of effect on the overlaps, but the rest should be fine.

Good to think so - thanks.
