pre-harvest glyphosate on Canola

[ado089]

What pissed me off was that it worked on the really late flowering plants and the really early stuff that was pretty much mature but it did nothing for the stuff that was about 60% and needed a push. I would have even been happy turning it to pepper but it did nothing. At 80% you're only a week away without a desiccant.

ado, heat works like reglone, just a bit slower. If its still actively growing and there is sufficient water in the plant it easily outgrows it and the plant continues growing.

Something to keep in mind when using heat or reglone.

Its a harvest aid, a plant that has already senesced is the only plant that can effectively be sprayed with heat or reglone.

Tweety, I'm aware of that. I've used enough reglone to know if it's too early it will burn and green up again. It was the initial burn that was absent.

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.

[tweety]

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.
