I planted a very small prunes few month back, it grew 2 feet strongly

the leaves have small holes in it, they are droppy, many become
yellow. Most have holes except
the young one.

I use Ortho Garden Disease Control, no good. Use different product to
keep insect away, no good.

Go to nursery, they point me to different directions depending on whom
I ask, they are few time more expensive than the tree itself.

the branches become darken as if they have fungus infection, but buds
grow on them.

see some flies who use the leaf as bathroom or nursery for the young.

Out of wit, anyone who has idea what happened to the tree and how to
cure it?

Obvious to me that you bought infected nursery stock. Since you
haven't any time invested in that tree I would dig it up immediately
before it infects your other plants and bring it back where you bought
it and see if they'll return your money... if not just leave it there
(not worth arguing over a plum tree), you don't want that plant on
your property. In any case never buy anything there again... you
definitely do not want a replacement tree from them. Then heavily
drench the spot where you planted that tree with a general
insecticide, Sevin is good....

If it is indeed fire blight, insecticide will do no good what so ever. Get
it diagnosed by a a reputable source.
