My apricot tree has developed reddish spots on the leaves which I think might be bacterial spot. 

I'm really concerned as I know that this can affect other stone fruit trees but by necessity, all of my fruit trees are in large pots and fairly close together.

I can't find any info on treating this so would it be appropriate to spray them all (apricot, nectarine, cherry, apple) with Bayer Fruit & Veg Disease Control and if so, how often? 

There is no fruit on them as this is their first year and I would be gutted to lose them.

I'm afraid I don't know anything about bacterial spot and I'm not sure about the spray treatment but perhaps move the plants further apart to allow better ventilation to minimise the infection spreading.  Also, remove any infected leaves as you see them, and burn rather than compost (that goes for all the leaves dropped in autumn to remove a source) - avoid touching healthy leaves after handling the others.
