I reckon the dynamic lifter is attracting All sorts of flys / bugs probibly not the reason the layer is failing
And I don't think its a good idea to use dynamic lifter on pot plants it can become clogy reducing drainage and also can make the soil ph increase becoming alkaline .
Did the layer have plenty of roots? and did u disturb the roots? Did u tie the new layer into the pot so it couldn't move about in the wind ?

Don't use miticide unless you really have mites so you need to check what bugs you actually have. Capture some and take to a nursery for id and recommended treatment. Mites have 8 legs. Fungus gnats breed in decomposing organic material and like Dynamic lifter. The larvae are white grubs and the adults are tiny flies but should not affect the tree.
I am happy to use some pelletised chook poo on my trees but not too much and use other ferts as well.
You can sterilise any potting mix in the microwave or in an electric frypan. I put a 4l icecream container of damp mix in the microwave on high for 15 min (less would probably do but I want to be sure!)
I think the temp to aim for is 72 deg C (pasteurising temp which kills most pathogens and would certainly kill any bugs, eggs, etc) but I aim to bring it to boiling point (100C) to be sure there are no cool spots left in the centre, etc.

Has anyone used this stuff before?
what was the outcome?
will my tree eventually die from being sprayed?
Will it regain its original colour again?
white oils and the like shouldnt be used on junipers, it actually clogs the trees breathing holes and will suffocate the tree. I did the same thing and lost 3 prized junipers a few years ago..
make a proper ID by getting a sample and taking it to your local nursery. then use control methods as recommended. best way to keep your trees from this sort of thing is to keep them in the best health you can. a tree has natural defenses for infestations and can generally fight them off themselves if the tree is in good-great health. I rarely have any pest/fungus/bacteria problems because health is a key importance.
