pre-harvest glyphosate on Canola

[bluefargo]

Can't help you on the chemical jag. No experience with it. But I would like to comment on wind direction. Theoretically our prevailing winds are WNW. But some of my worst wind damage came from the south.

strange , the volunteer canola (rr nexera) was killed dead by heat in peas ,they did use high rate though $10 /ac with 240 gm transorb

There is also discussion around whether or not narrow leaf hawks beard (or any winter annual) sprayed in spring is better controlled without heat if under stress - but that doesn't help with small rr vol canola that needs to be sprayed. Tricky.

Maybe that means Express SG is a better option in front of peas in the spring?

yea we used express sg in front of canary and some other crops to help glyphos with rr canola . I was really pleased with the results .

So those with experience, would you recommend Heat alone with 20 gal/acre water or Heat plus glyphosate to desiccate canola?

We don't need weed control, just dry down. Also, I was concerned that if the Heat worked quickly the glyphosate would run out of an actively growing plant and be wasted.

X2 on the water. Lots is better.15 US works good.

Braveheart, but it will only work if the plant has reduced moisture and has begun senescing (dying). The water in the cells prevent heat from exploding them ie working like a slow reglone - same technique - and are able to repair the damage. If too green and living they will keep growing.

This limitation is not well advertised or known.

We were going to spray at 75% colour change. That's beyond the usual swathing timing.

We were happy with the job on the peas we did for seed with straight Heat...(20g/av 30ac per jug) But the late cereals and wildoats did not burn off as good as Reglone.
Very happy with Heat roundup tank mix on commercial peas. 12 days to brown dry down 14 moisture.

I'd save your money for the 3 days it may or probably won't bring it in quicker.
