Canker has been on pear tree for many years, but has spread to other shrubs in the garden.
Cankers are caused by fungal or bacterial infections. The best treatment is 1) optimal cultural practices to ensure that plants are healthy and able to ward off infection; 2) removal of diseased areas and rigorous disposal of fallen plant material.

It just got done blooming and the leaves shriveled up. We have watered it.
Pear trees are generally hardy and free of disease, however there are a few things such as pear blight that can get to them. You need a positive identification of what is causing the leaves to shrivel. Take some leaf samples to the nearest Extension Service, they will tell you what is going on, and what to do about it.

I have just bought a grafted pear tree. The varieties being Williams and Beurre Hardy. It has been many years since I studied horticulture in college and had to give up though disability so I have forgotten a great deal.
Both grafts are healthy, although the point of graft seem a little narrow to support the tree as it grows. Is there now a way I can thicken the main trunk or will this automatically strengthen as the tree grows? Also, with regards to pruning, can anyone give any ideas of when is best? Should I simply allow this winter to fully establish itself or should I be pruning from this year?
Many thanks,
Justin

Pear trees are 4 years old and have never produced. No flowers in early spring and consequently no fruit. Apple trees just beginning to produce (Sweet 16). No fruit on apricots or plums. Is the orchard just too young yet?
Yes, your fruit trees are still pretty young. I hope this resource will be helpful to you: https://www.gardeningknowhow.com/edible/fruits/
The past several years I have worked and worked. I thought about spraying Malathion every week on my 7 apple trees and 2 pear trees. I was soooo disappointed last summer. I worked so hard and they were still wormy. How can I ZAP those moths, worms, insects from ruining the fruit crop? There are also about 50 bee hives stored throughout the spring, summer on the corner of the circle about 1/2 mile away. What can I do? Please help! Thank you!!
Tricky question because Malathion is highly toxic to bees. This may be a good question for your local Cooperative Extension agent: https://www.gardeningknowhow.com/extension-search/
Also, this article offers suggestions for non-toxic control:http://pcmg.ucanr.org/files/171600.pdf
Every year our pear tree looks fantastic with blooms and then these black spots show up all over the leaves and most of the blossoms dry up. Why?
There are a number of possible diseases that this might be, impossible to say what it is without an in-person analysis. The best thing to do is to talk to the folks at the county extension service, before the tree flowers, and then later you might want to take in samples.

In the meantime, make sure that the cultural requirements of the tree are being met - a strong tree has the best chance to ward off disease and pests. https://www.gardeningknowhow.com/edible/fruits/pear/growing-pear-trees.htm
My trees used to bear good sized fruit, but in the last few years they blossom like a flowering tree but produce miniature sized fruit. Nothing that I know of has changed. Any ideas?
If you have had good growth of pears in past years, and now have a stunted crop, most likely their is some depletion of soil quality.
Lack of pollination could also be a cause for your small pears, so make sure bees are welcomed to your garden. Pears don't send out a large amount of pollen scent, so it's important to attract them by other means.
Here are a few links about care of your pear tree and pruning guidelines.
I would suggest a soil to determine proper fertilizing of your trees.
