7 years I believe is how long wild oats can lay dormant.
I've heard up to 80 years.
That is more like it
I ploughed a neighbour field 4 year ago here first time since 1952
Bloody wild oats in it
Docks are 80 years or more. Haven't heard of wild oats lasting that long.
If you spray properly for a few years and rogue stragglers (shouldn’t be any where you spray) you should wear them down in a few years.
I did a project on wild oats in university, in general, the seeds don’t survive beyond 13 years maximum.
Clever plant. The barb (hair) on the seed is actually twisted like a wire rope. It will bend when wet and straighten out when dry - this movement will allow the seed to pull itself into cracks in the ground.
Look at the barb under a magnifying glass and you will see it’s coiled design.
Weren't you lucky you went with the Axial Pro! Must be over 20 years ago since that field was ploughed let alone in tillage!
I've been spraying the same two fields for wild oats for twenty years, haven't seen one in it since I've been spraying it. If I didn't do it next year what's the chances of them being plagued with oats again? I'd hate to chance it, might leave one tramline out for curiosity though.
In theory you'd imagine in a plough based system every seed ever released would have a good chance of germinating and then getting sprayed off. I also roundup off all tillage fields every December. In an ideal world these fields should be free from wild oats.
Wasn't I just. They're that much behind the barley they'll be very noticeable in the sample too! Oats going there next year anyway
Apart from the spring germinating ones
They'd nearly be blowing in the wind in the adjoining townsland anyway!
Yes plus the ahem 'anaerobic' nature of the soils there mean they'll be viable when dug up by aliens in a thousand years.
Farm was rotten with wild oats when I took over 7 years ago. Up to last year everything got wild oat spray when I decided to chance not doing the spring barley as felt it was under too much stress with drought. Was easily rogued so decided not to spray for wild oats at all this year. Big money saving and seem to have very few oats to rogue so looks like it was a good decision
Yes the cost does add up significantly allright.
The difficult decision is when to chance stopping the spray routine so.
I don't think I will keep spraying it for the next 80 years
Chance a few acres to start with. You will generally spot them coming through before the final timing for spraying them. Not ideal but it’s a get out of jail card!
Put in troops on the ground to assess the Barley. I might call into Easons and see if any of the Vulture funds or the Criminal Assets have any decent yachts for sale. If we get heavy weather I will be sitting out side Green Acres singing Follow me up to Carlow trying to fill a hat with coins .
There are plenty of dimples after last nights rain here in Wexford anyway!
There’s a few in Cork as well!
It seems the later sown barley is worst affected. Anything sown at the end of March is lightening off now.
I came on this 2 weeks ago
Ahh shure your only jealous you didn't find that niche market
Given that's the reduced section I'd say it's not selling well.
Could be a good business in that, sterile brome black grass and wild oat mix, convince the vegans that it's the new superfood and away we go, no more resistance to worry about
You wouldn't want to be getting human sludge though or biosolids or whatever it is these days
Bit ruffled but the amount of weeds coming through
