I agree with your Agronomist.

Bear in mind that BASF are selling products that manage the disease.

surely its too soon yet?, although I suppose it depends on how developed the crop is. Most crop around here (Cheshire) are only just starting to flower.
The most high risk time is when the flower petals begin to fall and the weather is wet/crop has a dew, meaning that the petals stick to the leaves and transfer the disease

I shall be going for LLS rather than sclerotinia so timing as normal for me, 25 days after previous teb application (got a feeling it could be LLS year but hoping not).
@Fromebridge - please let me know if you'd rather I didn't put these up - I'm sure you recognise where this picture came from...
Just thought I'd post the odd taster of what resources members have at their fingertips...

Am a member but can't find the 'sclerotinia risk charts' on the website... Any pointers where to find it @Brisel?@Fromebridge - please let me know if you'd rather I didn't put these up - I'm sure you recognise where this picture came from...

No problem, anyone can work out their own temperatures and do a similar chart if they have a couple of hours. Not everyone would believe the data anyway as they go by sclerotia germination and what their agronomist tells them
Ugo, you need to log on to the new niabtagnetwork site, you should have been sent access details, then look in crowd source, sclerotinia then risk alert (if you've entered your own farm)

Also bear in mind there was little or no germination in 2007 as it was too dry.BASF's sclerotinia monitoring site; http://www.agricentre.basf.co.uk/ag...ia_monitoring/osr_sclerotinia_monitoring.html

PM me or Fromebridge if you're having troubles finding it. It should be in the new website as described.

Ahdb trials show a yield increase even in the absence of disease I believe for a flowering fungicide. Agree this would be a low risk year
And that is the only year I didn't spray, boy did I regret it!!!!!!!!!!!!!!!!!! I have never seen sclerotinia like it, never, ever again will I omit it, the crop just died on it's feet, or at least the majority of it did. All advice was too dry so no need to spray, how very wrong that was.
It also happened to coincide with a hailstorm just before the crop was ready to cut, the dead plants from sclerotinia had little or no seed left most went from 28cwt an acre to 3cwt

I'm with @Badshot in that despite all the conditions being wrong for schlerotinia to be an issue, I would still worry. It's going to be a long flowering period, there's still too much LLS about so I'm just working through our rapes to treat. Also there's the physiological greening from the Az. It's not good when you spend all season questioning the agronomist and cutting rates then demand a spend on the rape when he feels it's totally unjustified.

Did a block of Nikita last night with 0.8l/ha of Highgate. It's been in flower for a good six weeks and starting to pod nicely.

i agree totally, with the cold nights they say there is no pressure and I suppose are aiming for one spray programme, but I am nervous its going to be a protracted flowering period I am still wanting to go now and do a two spray approach but as you say its hard to keep the agronomist reigning in spend and then going over him on this?

Gone in with skyway this last three days. Forecast will bring sclerotinua into play from middle of next week I reckon and we are >20 podset plus >30d since previous fungicide so exposed to LLS which isn't hard to find.
Expect to go again with topsin in 2-3 weeks plus insecticide if needed for pod midge.
One advantage of going in now is not having to worry about insecticide plus triangle mixture.
