Disease identification
 

Do anyone knows what kind of disease this is?

The younger leafs fall down on touching and they have this strange design....

If you don't get any help, send your picture to Nina Shishkoff, who is a plant
pathologist,

Looking again, my guess is rose mosaic, a virus disease. Dig the plant up,
destroy it, and don't plant another rosebush in the same place.

Before destroying the plant, and if you can't afford to virus test, I'd try
treating with an all purpose micronutrient. Roses respond in some rather
weird ways (and some predictable ones too) to lack of certain micronutrients
such as zinc, molybdomen, copper (or its overdose), and others. Buy a
fertilizer with a complete micronutrient additive and spray on the leaves as
well as drenching the roots. If 2 or 3 of these treatments doesn't cure the
problem, than it's probably fungal or viral. Treatments of Dithane and/or
Physan might help. If not, follow Iris's advice.

Rather than guessing send it to an independent lab. It will need a 1/2 cup
sample air dried. Cost is about $15. If a nutrient problem, they will ID
it. Send a note asking for help. I used to do this for a living.
