Sclerotina alert....

[furrowtickler]

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.

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?

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.

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

[wd9]

Two things. If the S varieties were the
answer, we'd all be growing them.

What we need are traps, like insect
ones, to accurately determine via PCR if
spores are an issue. Like you furrow, I
need to be able to detect that 1 or 2 in
10 and use fact to determine thresholds
and spray accordingly.

So lobby the provincial canola
organizations to make this happen. It'll
go a long way to making spray decisions
much easier.

Sclerotina canola will be the answer, IMO, time will tell. No diff than blackleg resistance. Have you tried one yet, side by side? I could not get that link to work. I have seen almost all data from everyone. This year's set up was a no brainer for us. The table was set at end of May and early June and dinner was served in early July - in this area. Now the heartburn is hitting hard. For me the piece of mind is huge knowing that there is a much much higher level of tolerence in the crop I grow. That is why we also grow Goodeve mige tolerant. Woundering weather to spray or not is more stressfull than actualy doing it, and far less expensive not to worry at all. I disagree with you on one thing, that if scerotina levels are high you have to spray anyway that is b/s. Right now the S52 has less than 5% infection and we have Liberty and r/r in checks with over 30%. Take the loss and price , no other time in my career has a tough decision been so easy. Still hurts to write the check, but seeing control levels in the S52 and sprayed canola i know the payoff will be at least tripple. Never did say anywhere S52 was the rock star but we have seen 60 two years ago and this year it is looking good so far. Still a long way to go though with storms every 3rd night.

Peace of mind is important too.
Schlerotinia resistance is a tough nut to
crack and will be quite a while for
products to appear. True resistance that
is.

With $14 canola, it was $12 for product
without bundling. $20 total including
custom application and for the cost of 1.5
bushels I have done my best (not a new
premium product but even that would have
cost 2 bushels/acre).
Lets me sleep a bit easier.

Boys this years canola had environmental factors
that are taking yield and theirs ps all you could
have done.
1 st aster yellows, nothing controls it's like ergot.
2 heat at flowering probably did more damage
than anything. Full flower in 30 plus temps.
Flower blast happens after 28
3 wet muddy spring to seed in.
4 some new varietys aren't worth jack shit.
5 mother nature wins all the time.
