Oilseed Rape after Beans

Residual weed killer might be a problem.

Thinking of the residuals, I looked up the label for metazachlor. You could drill beans in the spring following an autumn application of Shadow (metazachlor + quinmerac + dimethanamid-p) which covers the heavier duty residuals used in osr. Kerb/Crawler is approved in beans at certain timings so I don't see major issues with this.
 
I'm considering growing Wosr after Beans on some small fields to help with my rotation.
Is it a good idea ?

Like this idea a lot except the other way around due to the general september harvest date of beans on this land. If the osr could auto cast on then the beans no tilled then surely the following wheat would be relatively clean. Might help us with the flipping ryegrass that is in abundance and just keeps coming back.

I think No till beans could work into OSR stubble, should make for a kind seedbed. I have found by DDing beans in the past weeds issues are not so much of a problem. But for me this year the crop growing is beans, so wosr is plan A for now. The weather as always will determine if I need plan B.

We double cropped winter beans once and they did well.

How are you dding the beans though?

I have been thinking about this today, except the other way around. WOSR WB as a double break on our worst grass affected fields. This would give us two years of kerb/crawler so should really help to clean the soil up. we also are now getting lots of charlock/cranesbill in the WOSR so WB would also give us a chance to clean this up (Nirvana) as well and put a legume in the rotation. What are realistic WB margins though??

Could I use Nirvana pre-em, Crawler post em?

Going back to the original proposal, if you did grow rape after beans, then using Nirvana on the beans may be a problem, as the imazamox will cause issues for the following rape

Imazamox applied 10 months before the osr should be ok. I'd be less confident using it in front of March sown spring beans with osr sown in September without much topsoil incorporation. I've found spring beans to be quite dirty if dry early in the season so switched away from Nirvana pre em to clomazone + PDM then follow up with bentazone+ oil as contact material.

Would 2 years of maize have the same effect?

Could you not inter row plant, or maybe spread, the canola into the beans 6 weeks later ?
Manipulate quickest & slowest varieties to bring dates closer together ?

It could be done with RTK and a good operator. Spring varieties of both beans and osr wouldn't have vastly different maturity dates & looking at the threads on peola (peas + osr) the crops seem to mature together anyway.

It wouldn’t work that way at all for autumn sown crops. Spring sown maybe. Several people on here have tried peas and osr which are probably more suited to sowing at the same time
