If it is a fungus please advise good fungus killer sparys.
Here are two articles to help you determine what's going on with your tree:

Since you'll be removing some diseased parts of the tree, I would suggest you take a stem and leaf to your local gardening center for recommendations on how to treat the problem. We don't recommend specific brands, and it would be best for someone to have a good look at this before deciding what's needed.
Hello I planted two pear trees very close to each other, about 2 feet apart. They both also got planted closer to fence. They are more than a year old, so far good. Can I leave them like this or uproot and replant them?
It may depend upon the variety you planted. If they're dwarf trees they will last longer being this cramped. If not, you may want to transplant them before they get too large. Even dwarf varieties generally need at least a few feet between them, so give this some thought.

Established pear tree is healthy and flowers every year. However, no fruit is produced. I wonder if it needs to be pollinated - if so, how do I do this?
No, there are likely many insects in the area. This will not be necessary. It is likely a soil fertility or pH issue.
Testing your soil will reveal what needs to be done in order to bring it back up to par. These articles will help:

If you happen to have a pear cultivar that is not self fertile, then you will need a pollinizer tree in your yard. This will be a compatible pear variety to yours. You will need to consult the nursery that you bought your tree from in order to find out what will be compatible with your tree.

Thanks BushDoctor for your guidance. Over the last few days, the tree has become obviously distressed and many of the leaves are turning black. I fear I am going to lose it. I have not yet checked the soil, but it seems more likely that insects are the problem - particularly since the flowers were so healthy and plentiful. Would it do any harm to spray with an insecticide?
I have picked some pears off that have just come through black
Here are some possibilities:

Hi, I have a pear tree that is about 2-3 years old. I am noticing that something is happening to the leaves of this pear tree. I will upload images of the current state. Please let me know what seems to be the issue.
I believe this is related to your other issue. Wet, or infected soils.
I have posted the fungicide article on your other question, but I will include some articles on the care of pear trees, as well:
The tree is one of six miniature fruit trees. One I know is a pear and I know two of the others are apple, but not the one that is diseased or another one that is showing signs of the same thing. Can you help please?
Is your weather suddenly hot? That can cause leaves to curl as can overwatering or insect invasion. There is a fungal disease called peach leaf curl that affects peaches and nectarines. Pears also have a leaf curl disease.

I believe that a pear treen is grafted from a quince.
Yes. Always prune out any branches coming from below the graft. If you don't, it could soon take over the whole tree.
