Pruned trees dying where cut

Hey there. I pruned ALL the smaller 3-4 yr fruit trees on our farm earlier this winter. We had a warm winter and decided to get a good start on pruning... I was so proud and trees looked so good.I imagined them full of leaves and full of fruit.I also had just come back from a Permaculture Meetup in our PNW area on tree pruning even though I knew mostly everything we talked about and have pruned many trees in my years.... I disinfected my shears etc. Now We noticed that the trees look like they are dying and the branches where I cut are definitely showing signs of unhappiness. This is not good. I can't lose all of these trees! The manager says I cut them wrong and they were too young to cut, that the last manager cut the gingkos down below at this age and the same thing happened.... I did minimal pruning to establish proper branching. I admit some of the cuts are bad angles (horizontal) where water can accumulate and possibly go down into branch. But I knew enough NOT to make cuts like this and tried not to. Now this sloppiness on my part may cause the trees to die. ?!?!!! many of the cuts are good angled but it Looks like some kind of disease. It may have been wet/raining the day after pruning. Is there anything I can put on like an antifungal decoction of some sort? should I cut of bad parts? argh.an info, advice...

Hello Heather, can you post a picture?
