Can you tell me if foster 100/6 is good for asthma thanks?

Very likely: Foster 100/6 is a combination inhaler containing beclomethasone and formoterol. This drug is undergoing clinical trials currently for treatment of copd. While this particular combination is not currently available in the us, both it's components are available and similar combination medications are used commonly for treating asthma. Based on this i would say, yes, this would be good for asthma.

YEs it can: This european combination of a steroid and long acting beta agonist is very similar to product in the us called symbicort (budesonide and formoterol) (the steroid is different but works the same way). Asthmatics who require steroid "controller" therapy but also benefit from long acting agonist therapy (usually moderate to severe asthma) can be candidates.
