Sclerotinia pics

[SASKFARMER3]

Ok get better pictures because that's not bad. If
the stems are dying sclerotina but from the first
two crops heat stress at flowering. Still a 25 to 28

I thought mine was a result of seeding some on lentil stubble but checked the stuff seeded on cereal stubble and its the same thing. Infection levels here are low but scattered throughout the field (5-10%) with some isolated pockets a little worse. This is something we now have to be aware of and assess risk accordingly from here on in this area. I never knew this prior but most data I have read since seeing it suggests the yield loss is typically half the infection rate. Therefore 50% infection results in a 25% yield loss etc. Is there any truth to many just doing the 1/2 rate split apps of fungicide and then not doing the second application?

Saskfarmer: Let's say it "could" have been 40 bu/ac. Now you think it may be, say, 27. That's 13 bu difference at (pick a price)= holy shit I should have sprayed. LOL. Nobody to blame but me.

Looks better than mine!


I guess it's hard to tell without seeing stem length...
IMHO still a 30bu crop... don't see any Asters in it.

Send picture of the underside of the canopy with
stems. I'm betting their is jack shit you could have
done to get the crop any better. 37 temps at
flowering with wind is your yield robber.

I'll trade you for any one of mine canola fields, and you can pick the field you want!!

Sask: the yellow tinge of the top of the crop is simply an extension of what is below it. It should be a green colour not yellow for the number of days it is seeded. Flower blast will leave blanks on the stems not white and grey discoloration of the stems below the pods--come on you've been farming long enough to know this crop isn't right especially with all the info I provided.

Where SE of Regina. I'm heading to Bismarck in a
week and taking that highway. Looks like heat.

I agree it's not the nicest but take a drive a
majority of the canola crop out their isn't as nice. If
the stems are drying up it sclerotina. Did any
neighbour spray later in flowering in area what do
his fields look like. Let's all face it it 2012 will be
the year of the cereal in western Canada for yield.

Hard to tell from picture. Based on my experience, there will be no doubt at harvest if sclerotinia was present.
Caution, one year the number of sclerotia bodies in the grain sample nearly exceeded limits.

[SASKFARMER3]

True when your swatting dead grey stems all over
then yes it's bad. Don't swath to early.

Don't be too hard on yourself farmaholic. Common practice in our area took time to evolve, with quite a few still not using any fungicides.
The sclerotinia decision is the worst one to make because you can't see it, and you spray pre-emptive. A 'leap' decision. Insurance?
A day after spraying peas a second time (maybe unneccessary), I found an old notebook listing prices at $3.54 for peas, $5.60 for canola. Sobering thought. "How would I do that now?"
After last year spraying wheat has become commonplace!?
Good luck
