Submerge the entire tree n pot underwater for 20 minutes, then spray with a insecticide

Bringing it to a boil should be enough to kill any virus, but I will also add a few drops of alcohol just in case. I've been using it routinely for about a yearish, but occasionally for many years when store bought stuff failed, even on tomatoes and peppers. I've yet to have a problem. I'm either lucky or doing something right.

I tried this solution and didn’t work. Please see photos on my first post. These insects are not similar to what I have in my tree, they are tiny white sport on the leaves that are barely visible. I managed to take the photos with a macro lens.

Is this safe for a Chinese elm?

For 20 minutes, yes. It takes a long time to drown a tree, but not long at all to drown a bug.
Oddly, we still don't have a good idea what these things even are.

Before resorting to chemicals, just submerge the entire tree in water for 24 hours.
It will not harm the tree at all.

I don't understand. You realize neem oil is an organic, naturally occurring pesticide that has been used for thousands of years? I use neem oil on literally 100's of trees every year - less as a pesticide and more as a deterrent. Japanese beetles hate the smell. So does my wife
I actually like it. Smells like... victory.

I have aphids for the second time this year... and only on my Japanese quince, including now on my chojubai. I didn't have neem oil, but I had some Sevin spray from the last time I had this issue. I sprayed them 2 days ago, checked yesterday and they were gone. I'm going to have to try what Jelle mentioned about granular garlic in the pots to prevent them from getting into the trees.

Seven, even though it is not the Seven of years past, always exceeds my expectations. Great stuff.

Same here, I never heard of it till I had the issue of whatever was eating my trident leaves last year and one of my neighbors told me to give it a try. I used the powder on most of it, and the spray in parts I couldn't reach. No more holes in my leaves after that.

Can you post any clearer pictures of the actual insects? Your photos arent very clear so its impossible to be sure if they are aphids, however for such a small tree If you submerge the tree canopy and branches for a couple of hours in soapy water that will kill aphids and most other sapsucking insects [ie use washing up liquid at normal strength used for washing dishes] Are you keeping it outdoors? Elm are pretty tough so it will probably recover well but with the heatwave conditions here this summer and the chemicals you have sprayed it with this probably stressed and scorched such a small plant and recovery may take time .

Sevin may be effective for killing insects but unfortunately its not that great for wildlife generally as its also highly toxic to honeybees and other pollinators which is why many other counties including Britain have banned it!

These tiny things NOT aphids
! Can you see move? Any bugs seen on personal trees have been removed with insecticidal soap. Have had only bad results from neem and will not use again.

I cannot see them move but they are defined spreading as every day I can see more and more white spots on the leaves. They like young leaves on new stems. Today I will take more photos with my phone so you can see it in scale.These tiny things NOT aphids

No honey bees in my area... other than a bunch of wasps which I really don't care much of as my daughter is allergic to them. Here are the idiots that were in my quinces.Sevin may be effective for killing insects but unfortunately its not that great for wildlife generally as its also highly toxic to honeybees and other pollinators which is why many other counties including Britain have banned it!

@ficusmania - my guess would be white fly. But cure for white fly usually cures aphids and many other pests. It "could be" one of the mites, spider mites tend to be red and live under the leaf, but flat mites and other species look a little different and localize in other areas including upper face of leaf. Cure for mites must be different, as mites are arachnids, different neuro chemistry than insects.
In the UK and EU the range of pesticides is much more limited than in USA, most USA products are not available in EU or UK. @AJL and @leatherback and @Wires_Guy_wires will have better suggestions than any of the USA based members as they will know products available in UK.

Most folks haven't learned, yet, to use/apply/mix NEEM correctly....this, I believe, correlates to the "mixed results" you hear of.
Agitation and treatment schedule are more important than exact mixture ratios.
Also... Aphids CAN just be manually removed.....
Also.... They can't breathe water (dunk your tree) OR sharp particulate (dust your tree with chalk, ash or DE powder)....
A good hose blast first will remove excess.....
But NEEMing CORRECTLY.....it ALWAYS "does the trick", at least for me.

Hmmm.... This ALSO resonates strangely in my direction.
Systemic insecticide, when used correctly effectively DOSES your plant cell's "transfer fluid" with poison..
a plant with systemic running through it's veins really won't be eaten... Or else the pests die.... We then treat again. For the eggs (anywhere from 3-14 days later ((product and critters depending)))... With NEEM the schedule is different, but if you treated with systemic, and are STILL having problems, it is possible that your tree isn't moving it's "water" around correctly, anymore.

Sorry, I don't know about the UK guideliness for pesticides anymore.
But if you can find Karate from the brand Compo. Then you're pretty much good to go.
