    It's pear rust.
    There's not much you can do about it, but so long as it's not very severe your trees should be ok.

    Well now I've heard it all lol! I take it WD40 won't work?!? Ha ha!

    My dad wants to pluck all the bad leaves and burn them. My mum thinks that new leaves will return with the same problem.

    :) - my pears also have it, but I've not tried WD40

    It's a fungal problem. The spores that are produced on the leaves of your Pear trees can only infect species of Juniper. The spores cannot re-infect your pear tree.
    At this time of year the 'explosions' on the back of the leaves release the spores and they find a home on a Juniper to over-winter. In the Spring the spores that have been produced on the Juniper are only able to infect Pear trees - and so the cycle continues.

    According to the RHS, if you want to prevent it happening, you'll need to remove all the Juniper in a 1/2 mile radius - good luck with that :)

    Thanks Pete8, that's good to know. I'll let my folks know. Do you know if they can still eat the fruit, if the trees produce any? I appreciate your help.
