Doesn't help that winter osr plants have been bred to be palatable to everything, and have pee poor vigour. Even compared with the plants of ten years ago like Excel, modern ones seem......like the feeble cousin.
Isn’t he saying look how neonics don’t really work here...It gets a lot colder in Canada in Winter. Can’t compare the two nations
I'm not sure if thats quite true. osr was thought to be introduced by the romans but from limited knowledge the growing of osr gradually died out before coming back a bit in the middle ages from what I've read. So to say it was grown successfully for over 2000 years seems at the very least dubious as for one it wasn't grown constantly for 2000 years and secondly how do we know they grew it successfully?neonics have nothing to do with the loss Osr in the uk - it’s just the scapegoat as we can just never accept any responsibility can we ?
osr was grown by the Romans and i’m fairly confident they had no chemistry at all ! what changed in just 20-30 years after a couple thousand successful ones ?
it’s gone because an entire generation farmed like idiots thanks to brain washing by “big ag” and a succession of very badly thought out subsidy schemes
Exactly, I am open minded and don’t use much insecticide at all, but a lot of agchem wasn’t introduced just to make money, there was a need for it and it worked.I keep telling you Clive in pre ag Chem days CSFB was a pest and crops regularly lost to it. Normally kale as it was the most grown

£20 quid a day they can come whever they like. Metal detectors too. It's leisure, not a service.
Could be, I may have misinterpreted.Isn’t he saying look how neonics don’t really work here...
Also cold doesn’t really matter when the insects survive it.
Fantastic post.I'm not sure if thats quite true. osr was thought to be introduced by the romans but from limited knowledge the growing of osr gradually died out before coming back a bit in the middle ages from what I've read.

Clearly our intensive osr rotations have not helped the situation but to say neonics have nothing at all to with the loss of osr in UK is clearly not fully correct. It is surely a whole range of things including the way its been farmed and the loss of neonics that have combined to lead to this point. Climate change cant have helped either with much warmer years and very few winter frosts.
I'm not one of the previous generations that you refer to as idiots but i think to call people idiots for what was done in the past is ridiculous. Everything is easy with hindsight but you have to do what is deemed right and hopefully profitably at the time. Farmers may look back on us in 30/40 years time and think that we are idiots, who knows.
Lastly, a question I've been wondering for a while is, why have all the pests become resistant to the insecticides that we use but the beneficial's have not? You would have thought that eventually with the large increase of flea beetle eventually there would be a large increase in its predators?
How many? sorry....keyword alert.
Neonics are used everywhere here.Could be, I may have misinterpreted.
I thought he was saying that where neonics are not used in Canada (I have no idea whether they are or not) the crop yields well. ie cultural controls work.
Could be wrong though
It will grow but don't trust those who say it will grow fine. It really doesnt yield well.Anyone ever used home saved hybrid seed? Think I am a bag short of new seed for next year and thought I’d try some off the heap just too finish off. Know people say not to do it but thought I might give it a try. Volunteers seem to grow fine
I am fairly sure that a good autumn seedbed and rapid autumn growth here gets the seedlings away from grazing danger here even without insecticide. The problem is then the egg laying into the stems in the autumn. By the following spring the larvae are hollowing out the stems and the crop yields very poorly.Neonics are used everywhere here.
Some farmers may decide not to use them because there are years they don’t seem particularly effective but probably statistically most canola is seed treated with it.
Seed treatments are the only neonics we’re allowed to usr I believe.
There is one type of flea beetle that is less bothered by seed treatment than others because of how it eats. But any stress in the seedlings like frost or lack of moisture and it seems most bets are off. The best protection is have the seedlings take off fast so they outgrow the damage. If I remember right that scenario gains only a 10% seedling loss to insects or something.
I wasn’t just posting about neonics. Canada has much harder winters and the OSR grown there would not be sown until spring.Neonics are used everywhere here.
