Sclerotinia pics

Most digital cameras are capable of a "close-up" view and it would be helpful in assessing what is going on in this particular situation...otherwise we are just spinning our wheels. It doesn't look kosher though...some ting is a wrong.

Agree with willy, I am 95% sure sclerotina infected about 30-40%. Also agree with S/F, do not swath on the early side. Again , field walks yesterday and today confirmed what is going on, early - bad infections in certain fields not sprayed.
One thing though, S/F - spraying was almost 100% effective and it is an increadable diff. It will make an easy $100/ac proffit - if it dont hail before combines roll. I will show results from check strips done in this area. Close to 0% infection on sprayed to 30 on non sparyed you do the math at current prices and 40 bus/ac "potential" crop at this time.

Each area is different our area we would have
needed multiple applications. one was not
enough, that's the experts recommendations. Yes
in a normal year, but what's normal anymore.
Great it worked in yours. Good luck with the
harvest.

In my 20 years in the canola industry (dating myself .lol) i have almost never hear of multiple applications of fungiside for sclerotina. Were your experts drumk or just trying to make you feel better cause you were at the lake at 20% flower?

I guess one other thing us with thin stands is that possibly the leaf hoppers could not jump from plant to plant. Looks worse in thicker stands.

Furrow I like you but no they weren't drunk, funny
year our way. More leaf hopper damage than any
thing.

All good, just hear the same thing around here from some who run off and play instead of looking after their crop for a few more days. Took me 2 days to spray canola. Still had alot of lake, fishing days afterwards.
All the best to you, I think the bloom has come off this crop substantialy here as well.

Sorry to here you think it's lake time. Study
growing conditions and crop. Your area lucked out
and will win prov best no doughty about that.
Aster yellow no cure and it gets wheat and canola
and barley. Also our test strips show very little
difference from what I sprayed proline, even
bayer rep says we would have needed more than
one app with all the rain. Can't spray leaf hoppers
with Lorsban every three days. So take your good
crop and be lucky.

Gee furrow you've only been in the game for 20
years we have since 1970

cut and paste from Canola Watch #23 canola.ab.ca

Fungicide: Fields that were sprayed with fungicide in the 20% to 50% flower window can still have sclerotinia. Fungicides will reduce the incidence and severity of infection but will not eliminate sclerotinia completely, especially if conditions are favorable all through flowering. Spraying twice will help prolong the protection when the flowering period is extended, but even that will not completely eliminate the disease when pressure is high.
