I recently bought a young ivory silk and 2 weeks later he look sick...Almost all of the leaves are 'infected', there's no parasite that I can see so I think it may be fireblight? Could you give me your opinion please, I'm really worried and thinking of bringing it back since it's still it's not planted yet...

I agree, it may have a bacterial infection call 'Lilac Blight'. Take it back.

I don't know where you live, but here in the Midwest, this kind of bacterial (usually) blight on lilacs is not uncommon and seldom life threatening. It is not fire blight. Symptoms begin to show show 5-7 days after infection, which occurs during wet and usually cool weather in the spring. Trees grown in pots are especially susceptible due to the inherent stresses they endure. While this may or may not have began before you bought it, the nursery should take it back, pursuant to their guarantee. Realize though, that this is no one's fault, and if you get another one, there is the same chance that the blight will occur again, given the same conditions. This is normally a temporary problem in the Midwest and requires no treatment. Unfortunately, the disfigured leaves will remain for the season, as lilacs (including your Japanese Treelilac) don't grow much beyond their spring spurt of growth.
