glyphosate on RR canola,,,how many grams?

[boarderbloke]

How many grams have you been able to put down? Looking at a split application(likely will be 10-14days apart), moisture conditions would likely be regarded good to excellent.
Would like to use 250g for the first and 200 for the second. Have used 400g in the past, 200g plus 200g, have also sprayed 400g in a single shot.(of course old liter is 356g)
How many grams would be reaching the max on DeKalb RR

I would still go with 200grams per application X 2. If only going one I would use 250grams. Its pretty much impossible to hurt, you sure can't see any overlaps or double sprayed spots.

What the heck are u trying to kill at 400 grams?

Guys spray way to much glyphosate on RR canola that is not completely resistant to glyphosate. RR2 is much better. 180 is registered for 2 pass. You may not see the damage, but its there. especially the later you go.

You didn't actually say what crop you are spraying. Corn, canola, soy?

Maybe use tweetys info, seems to know it all. I've even used full liter on the bolting flowering crop in a wet boggy field and it didnt even touch the canola. Works great can't kill that crap. If you touch it you probably have express residue in your sprayer.

It was explained to me that it stops the plant from growing but I wouldn't know it to be true

tweety, canola in the topic line. Going after some foxtail barley in areas that haven't been seeded for the last couple years, but are getting the land back this year. Did get a good burnoff before planting, but the odd one was missed and a few younger ones are coming now, 3-4 leaf stage.

Thanks breadwinner, like i always say, Angryville, its the culture.

Anywhere from 11 to 35% yield loss.

Topic line, shoot, read the post a few times, but missed it in the topic line. Sorry border.

Its always interesting and yet disturbing to listen to farmers say it doesn't harm the canola.

You can use a full 360 for a one pass shot, it is right on the label. I do know that volunteer rr canola will not die using 720 in a glyph alone burn off, and still produces seed and lots of it.

You learn a lot when it is too wet to seed!

[tweety]

Half a liter of 540 per acre in single pass. Third of a liter in 2 pass. Up to 6 leaf.

That's on the label.

Of course you can spray 2 liters on it and it will "survive". I understand sometimes we all have to spray later and blast outside rounds and low weedy spots. But you can't say it doesn't hurt yield. That is absolutely incorrect. Its herbicide tolerant when its small only, definitely not resistant.
