Spraying Roundup on canola late

[farming101]

What is your experience with spraying roundup in canola after bolting has started?
I am thinking with the crop under stress from excess moisture it could be a big mistake this year.

Haven't grown RR in while. Maybe varietys have improved.
All I know is that I have seen it lead to. (Cause ??)
A section of abortions on main stem.
Expensive agronomist can natter about manganese and boron and that's nice, but I would be careful. Last I knew company wouldnt admit to it.

Well I finished 800 ac of spraying glowering canola... would we do it on our farm? No.

I have sprayed late before and it has not hurt it at all. The weeds will cause way more yield loss and mess for years than the 1/2l of roundup. I have even sprayed when the field was yellow and it turned out fine. Get it done you wont be sorry.

Thanks for the replies. Unless there is some awful weed problem I don't think it's worth the risk.

I did it in 2010 with waterlogged fields and where I sprayed we still had a crop and were I didn't it was a total cluster%$^%. It wont stunt the crop, RR canola is impossible to hurt when flowering, just try and spray it out of your summerfallow.

I ****ed myself pretty good by not spraying once

Obviously situation specific. Risk/reward.

Let us know how it turns out. I'm curious.
