Sclerotinia spray.

[snipe]

What are people using this year?
is this a bit over kill, .3 (60%) filan with .6 (77%) remocco/metconazole to act as a bit of growth reg and make it bush out too. It’s a good thick tall crop and hopefully only going to spray it once.

If it stays cool there's a fair chance of sneaking through flowering with little risk of infection, so do you even need to spray?
My default position is not to spray unless there's a good reason to. I appreciate the opposite is true for most when talking about sclerotinia.

The Filan seems usual.
Not so sure you need the pgr tho. Had you applied any pgr previously?

It's the showers that'll be the issue though? Enough to stick the petals but not wash them off.

A job I hate doing, along with the dessciation, but will grin and bare it next week

I was led to believe the overwintering sclerotia needs temps of around 15C to form apothecia, sporulate and become infectious.
Yes if the sun comes out and we get a hot 2 weeks, with the recent rain, canopies will be humid and the pressure will increase rapidly. But for now I'm not concerned at all. It needs to be wet and warm

Miles too cold
if it warms up a lot next week there is a small risk
