Lots here as well. Sprayed some and will do more as it comes to the right stage. Crop not the best but wet every night and windy every day which will spread spores from everywhere.Hmmm, looks like someone is away on holidays and not up-dating the map.
Lots of apothecia here. I will spray some for sure.
They are in fields that had canola last year, which would be this years wheat. Very thick canopy and moist at ground level. Just have to root around and find them while avoiding the mosquitoes.
We have been finding them in the wheat and canola fields. Don't really have to look that hard to find them. Lots of rain and really wet every morning has brewed up a perfect environment for it so far.They are in fields that had canola last year, which would be this years wheat.

If canola is thin and it gets drier from here out then it becomes a coin toss I would say. I actually have a fairly thick stand of canola so will spray.
Take note of the varieties and severity of infection. I had L150 with 100% infection 2 years ago, did 19 bpa! L154 on same field yielded twice that. Not all varieties are equal despite ratings. I actually harrowed some VT500 into some of the L150 stubble last spring(no other option/too wet) and it out-yielded the L150 with only the residual fertilizer from the failed L150 crop!
We grew L5440 and L140p and they both have blackleg along with every other farmer in my areas canola fields. These varieties are not as resistant as they used to be?Take note of the varieties and severity of infection. I had L150 with 100% infection 2 years ago, did 19 bpa!

So blackleg is becoming a huge issue IMO and is the reason why I am starting a major shift to other crops. I did put a Invigor canola variety trial on my worst L150 blackleg field from 2 years ago and will report back on what I see from that later. Need to know what to grow for canola going forward.
I don't know about that? There are many strains of blackleg and I think it is evolving from what I know of it. It really depends on how well these companies test/trial for resistance before they come to market. As evidenced by L150 the testing is obviously not up to snuff. I wish I could still get 5030 as it never was bothered by blackleg here when Dekalb and others failed on the same fields. But on we go to newer/better????/more expensive varieties.
Correct. Some fields not even touching. Did one field at half rate and one half of another field full rate as tests to see if one or other paid or if wasting money or prove if I should have done more.
