Post-seed glyphosate burn-off

[Jay-mo]

I'm looking for some advice on doing some post-seeding glyphosate on wheat next spring.
It sounds a bit risky to me.
Spray too soon and theres not enough weeds, spray too late and risk hitting your emerging crop.
Just wondering what kind of results guys have had doing this.

what are you seeding with disk drill or hoe? it will work well with disk drill.

What's the difference between hoe vs. disc drill?

Last spring did one field post seeding. Wind blew so 1 day late spraying, some wheat barely peeking through, some damage, good control of weeds-wish I woulda done it right!

in post seed burn off with disk drill there is less dust

[mustardman]

The hoe drill will cover up some weeds with dirt that it moves ,whereas the disc drill moves hardly any dirt so weeds are still uncovered after seeding

I'm using a hoe-drill airseeder.
The issue of dust and weeds being slightly buried are good points.

I suppose theres alot of issues to consider. It seems to me that if conditions are right for a post-seed application you're definetly ahead.
However, if conditions are not right a guy only has a couple days to make up his mind and then its too late.
Then it might have been better to do a pre-seed burn-off.

Have done quite a bit. works really well BUT if mother nature does not agree with your plans you can have a very ugly mess.

Had poor weather, could not spray for a week, damp, misty, but could still seed. We soon ate up the sprayed acres, and thought we could catch up post seed. Missed three ¼s one year and it cost quite a bit.

In a few situations I will still do it, but mostly try to do it pre. I liked it best on peas and oats.

Jaymo your burried weeds will not pop back out before your wheat has emerged, IMO. If you have not post harvested, then best to pre seed. I like to post seed peas because you have a dependable 11 days before emergence. Wheat usually emerges faster unless soil too cold.

We have "0" tilled for over 10 years, and this is the first year that we tried some post burn off. We rented some land that had been previously seeded into Invigor canola, and the field was really dirty. We seeded our wheat early on those fields hoping to get all the weeds incrop. Well the wheat sat in the cold ground for ages, but the weeds didn't, so we gave her a shot. We were skeptical, but it was either lose the field or spray...so we sprayed........and it was the best thing we did. Wheat was in the ground 7 days before we sprayed. Air drill used for seeding.

Pre-pass works great just before the crop emerges. You must have the sprayer ready to go. This has worked very well for us every year we try it. Even if the wheat/barley is just breaking the surface you will not damage your crop. Many times we have not needed to spray in crop.
It is a timing issue and may not work out for all your acres.
