Sclerotina alert....

[furrowtickler]

For those of you who never sprayed and in suseptable areas, it may not be pretty. Aster yellows may be the least of ones worries. Seen very severe infections in the check stips, worse than I ever observed before. Upwards of 40%, 5 -10 days of further maturation of canola will show severity. The stage was set for an outbreak in May and June - the first time in 5 years we had any real rain/soil moisture to activate it. Any heavy canopy canola in this area not sprayed may be in serious trouble. Just a heads up.

[wd9]

Maybe its your variety. Asters look worse
than they really are as they are tall and
obvious.

Aster yellow is really bad in East central manitoba. Had it back in 2007, where swathing canola crops that looked like they had the potential for 55 bushels that yielded 20 to 25 bushels, and in some cases were even down to 6 to 10 bushels. Some fields that year that we thought were going to be worse ended up being better than expected. Sclerontina seems like it is not as bad as expected. I think there is no sense in thinking about it, it will be what it will be. Wheat yeild will certianly make up for some of the losses we are going to have in canola. Still all and all going to be a very profitable year. Could be a lot worse.

Has SFA to do with variety unless scerotina resistant. Seen it in Liberty, R/R and clearfield. Swathing time will tell story, I am just giving heads up for those in this area. It is far too late but just dont be suprised when the crop lays down and is a bitch to swath if it was not sprayed. Half our canola is scerotina res and is less than 5% infected.

[wd9]

Its schlerotinia, and varieties have an
impact on infection. Even just standing
well has an effect.

The pioneer stuff is not resistant, its
tolerant. Yield trials show there is
little difference between it and top
varieties untreated which still most
times out yield it anyways. Looks can be
deceiving. Weigh wagons and identically
grown plot trials never lie.

[furrowtickler]

I hardly need a lesson on yield results or plot work. I also own a weigh wagon for 6 years. Low disease pressure years you are partly right. Time will tell on this one.
Have you grown the 45S52? Side by side in your own field with anything else? I have. Or going by propaganda spread by competitors?

[furrowtickler]

Spelling lesson , yes for sure.

[wd9]

Um yes.

Typical Bayer plot showing S52 is not
that special.

Pioneers own trial summary from all
sites. Again, not so special S52.

[wd9]

Perhaps you could point me to some
published trials that show the yield
advantage?

[Daylate]

S52 wAs in my opinion, a weak plant when we
seeded it. S53 is way better in comparison from
what I see so far this year but I still love h29's
yields. However im wishing now I would have
sprayed for sclerotinia cause the h29 has main
stems that are rotted almost completely off, still
looks ok but is going to dry up fast. the s53 has
a very little showing up so far, but does not
have that same heavy look to. I sprayed half of
every field last year and it was a waste of
money. This year the infection looks worse so it
might have payed, shit! That being said I bet the
h29 still out yields the s53. Oh and Bertha are
out there in pockets. We're too early yet to
worry about spraying here but stRt your checks
guys! Does anyone else Think we might possibly
grow ourselves right out of a profit in canola
faster than we first thought in the near future!?
We're gettin close now, don't stop feeding the
beast.

Last year was a completely different growing season, actualy the last five were. We had very little rain if any until the end of June. Thus the sclerotina never set in till late. This year the process started 4 weeks earlier, setting the stage for high infection rates. Nobody should be suprised at disease levels this year in this area.

wd9, you are right that Pioneer genetics is tolerant but they are getting close to a 7 out 10 in the "tolerance" scale. all other varieties are a 1-2 out of 10. If you are saying 45S52 is a couple bushels shy of other varieties that are treated (which is area speicific), i would say that you are way head finacially and time wise. The slectotinia genetics cost approx. $5-$7/acre compared to $25-30/acre slcerotinia app ( product with rebates and app). PLUS, you have to get it done in a tmiely matter but maybe you dont have the slceritinia pressure.

[wd9]

There is no industry agreed upon scale for
schlerotinia. If pressure is high, you
have to spray both. You may as well go for
the one that yields better. After all,
isn't farming about making money?

[tman]

What part of the prairies are you located in furrowtickler? I'm curious since from my experience in MB and SK plus hearing of the field scale trials in Indian Head, I'm quite reserved on the sclerotinia sprays on canola. You must obivously be in a hot spot for white mold.

[furrowtickler]

We are this year. North west Sask.
On average not a serious issue here, but this year is different b/c on the early loisture and sclerotia bodies built up over the last 4 years. Lentils the last 3 years were loaded and they don't just disappear.
Most years it would be a waste of time , this is about a 1 or 2 in 10
