Have you checked for red spicer mites as well. We have had a huge infestation of them this year.

Vance that sounds more like a pest for peppers than junipers.

The "latest" treatment is ZeroTol. It is little more than hydrogen peroxide, so you don't have to go through the hassle of buying a gallon of it on-line.
Get 3% hydrogen peroxide from your grocery/pharmacy store. Drench with one quarter cup peroxide per quart of water. Also makes a good general purpose fungicide/disinfectant spray at the dilution of 2 tablespoons per quart.

He means spider mites and they are juniper killers
I suggest you try to nail down what the issue is before you employ the shotgum method and start treating for something it might not be.
Shake the branches over a white piece of paper to check for mites
Examine the roots to see if it's really root rot.

Maybe I should have said a pest of those that view adult entertainment.
It was a joke. He obviously meant spider mites, not spicer mites.

Sometimes I fat finger the key board and if the mistake comes up with a comprehensible word the spell checker does not let me know. Such is the case when you can no longer feel your hands.
I just did miticide sprayings 2 weekends in a row. One of the junipers I did a emergency repot on--roots look inactive--no white growing tips

If you suspect root rot and do an emergency repotting, make sure you use an open mix that will allow the roots to breathe without drying out.
Otherwise make sure you don't OVER water after repotting, and make sure you keep your tree out of direct sun until it recovers. Bright light - but no sun.

Were the roots black, slimy and falling apart?
If yes then root rot
If no then not root rot

I may be on shaky ground here a bit, evidentiarily, when I say this, but I'll go ahead anyway ... the only roots that rot are dead ones. As others have alluded, look for reasons why the roots died. Overwatering with poor drainage could, I suppose, be one, as could pathogens or pests.

It's a good point, if roots die they then rot (decompose). Finding rotting roots in a pot doesn't necessarily prove the presence of a root rot pathogen.

I don't believe in root rot. I believe in bad soil and too long between repottings, with a helping of over-watering

Interesting article Wireme. It is inconclusive however in that it says similar symptoms of fungal infection can be shown simply as a result of the waterlogged conditions without any pathogen present. So I guess the practical takeaway is still to make sure your soil is well drained.

I have used Hydrogen Peroxide. This should help , be careful before watering. One teaspoon per gallon 3% . Hydrogen Peroxide will do all your trees good as it get Oxygen to sick roots.
Be careful to use diluted correctly though.
