The UK aphid monitoring network | AHDB
Found out about a network of traps providing regional information on aphid species and numbers.

Just to inform
Oh christ what have I done, thought it was quiet on here regarding this!
What threads are about, no ones really posted one until now from what I can see?

How to stop using insecticides?
I also went aphid hunting with the agronomist today on some of my wheat drilled on the 20th Sep. It's romped away and has nearly closed up the gap on avatar 25cm rows. DD x bean and OSR fields. We found a few green and cherry aphids in the middle of the field and quite a few more along a...

Mind even this didn't last forever, though less of an issue for you mainstream arable guys drilling that bit later.

Not used or know much about deter but if it’s anything like the insecticide we get on canola seed which is supposed to get protection from flea beetle it’s not worth the bother. Seed applied soil moisture activated after an average 5-6 days to emerge you’ll be lucky to get a weeks worth of f all after that.
Did it work better when it was first introduced?
Such a ludicrous amount of those seed dressings were used on everything all the time it’s no wonder they got banned
Now where have we seen that before?

One could spray twice in October, Nov, Dec, Jan and Feb, tramlines ruts up to the axle.. put insecticides in or leave it out results will probably be much the same, or am I wrong

No. Always been hit and miss. Sold as a wonder cure for flee beetles but most still need to spray. Past two years have been very high numbers. Lots of two and three passes with sprayer then a reseed. Hutterite colony not far from me reseeded 2500 acres and still no crop. All mine was sprayed early and it got away before the next flush started chewing.

Wrong, as I've said before on here, when you have been combining for 2 days and only harvested 80 tons of barley, when you have gone and cut a 12 acre field of wheat a couple of years ago that when you went to spray it and you couldn't because severn trent had dug up the gateway, you get the combine rolling and its only reading 6 to7 tons per ha when all wheat harvest it had been reading between 9 and 11 then this concentrates the mind, so okay I get that there are many in the country who don't have a problem or maybe never see it, but I hate it when we get looked down upon like we are the scum of farming because for some reason our area seems susceptible to bydvOne could spray twice in October, Nov, Dec, Jan and Feb, tramlines ruts up to the axle.. put insecticides in or leave it out results will probably be much the same, or am I wrong

Was that in recent years? I am not criticizing your use of insecticides, you do what you feel is right. They always appear on my recs, sometimes they go in the tank sometimes they stay in the store, depends on my mood rather than any science... Our worst year for suspected BYVD we did apply with the Autumn herbicide and again in the spring... There were aphids present during the mild January when the ground was too wet to do anything about them even if we had been willing to pay the contractor for another pass I consider preventative Ag chems as a means to reduce how lucky one needs to be... but for insecticides to be effective one seems to need either extra luck or impeccable timing
Virtually all of us have used insecticides at some point so shouldn't be looking down on anyone. That said the seem to be less and less effective and I have no doubt will be banned soon so looking at ways of doing without or removing the need of them seems a good idea to me.
