Herbicide Resistance

[flea beetle]

cultivator works wonders on chemical resistant weeds...

[Rareearth]

Once you have resistant weeds they will always be there due to the seed bank ( the seeds they drop for the next 10 years to germinate and regrow).

A one off cultivation or different crop type doesn’t eliminate resistant weeds, ( but it helps, just like normal good farming practices, clean fields, etc)

[AlbertaFarmer5]

On a similar vein, anyone have any solutions for agricultural topic resistance in certain posters? Or common sense resistance? Or polite, tolerant discource resistance?

It is an ongoing problem on this forum. The best defense I have seen is to use thread titles that are purely agricultural, such as this one.

That helps to manage the problem, but doesn't control it. Any better methods?

Dunno if ya read my post mate, that longbheld theory is being challenged here.

Can't imagine leaving a field go to kochia to graze. We don't have an option for that anyway. No more livestock. Cows generally aren't great kochia eaters. Not sure about sheep but that would have the neighbors talking.

Tweety. If you would have seen what I saw the two past springs I doubt you would think tillage is a real good option.

Forages would be better than tillage.

Or only targeted pin point tillage.

But wide scale recreational tillage is dynamite under some circumstances in some areas.

I've even seen wild oats worse in tilled areas than untilled, you could see the line difference. Buried every wild oat that was laying on the surface then he had a carpet of it.

Tillage might be part of the solution but it is no replacement for an integrated program in my opinion.....not here anyway.

Completely agree. Tillage is also a difficult option in crop, its why selective herbicides are pretty much the only option - and why the resistance problems.

There is another scheme: https://www.youtube.com/watch?v=-1CX2adzhoM https://www.youtube.com/watch?v=-1CX2adzhoM

Was looking at Avedex , but at $25/ac that option absolutely will never work
Lol 35 year old chemistry for $25 / ac , WTF is wrong with this industry

If you want it to work, you have to apply it on a Sunday when the sun is rising in the west and setting in the east and chant "long live Gowan" while swinging a dead chicken by the neck three time over your head.

No shit, read the label!

[farmaholic]

Just think, you might have to follow up with an in crop application of wild oat herbicide because ________. Fill in the blank for the multitude of reasons why the Avadex never worked.

[furrowtickler]

Or Edge or rival or or or

They should be viable add ons to a herbicide rotation , but priced way too high
Rival / Bonanza not too bad

you can lay on 540g/ac of glypho, full rate express SG, 4oz of 2-4D, and 2oz of banvil, and the kochia laugh it off!

1.3L of glufosinate at best kinks them.

540g of glypho with full rate heat, blackhawk, goldwing, aim, or even double rate distinct and they at best quit getting any taller... They still set seed and fail to dry down.

Hit them with reglone and they sort of defoliate. Sometimes they require 2 passes.

I think there is a common denominator here. Check your water quality. You may need to amend it with additives.

Water is not just water.

Water is not just water.

How much better can potable water direct from the Henry Kroeger Water Treatment plant be?

We've tried 5gal/ac, 7.5gal/ac, 10gal/ac, and even 12 gal/ac. We've tried spraying it in both directions to make sure all sides of the plant gets a decent dose.

EVERYTHING ELSE DIES! Kochia does not... If we were the only ones not getting results, I would think there is something that we are doing wrong. NO-ONE out here is getting results. The only thing that seems to make an impact is very strong doses of chemical with varied modes of action no more than 3 weeks apart.

As soon as they are past the rosette stage you are absolutely SOL here. And considering that they can flush after every single rain event greater than about 2/10ths, that makes for incredibly expensive chemfallow!
