What Is Happening To My Pears ?

[Nyboy]

I planted a lot of pear trees when I read they don't need spraying. Some thing is going on I hope it is not fire blight. Can anyone one tell me what ?

Black spot around leaf edge.

You need to spray a copper-based fungicide...

It might be blight. I had that with my Barlett pear (which produced 50 pears on 2015) LAST year (2016.) The advice was to cut back at least 8 inches beyond where the stems were dying and remove ALL leaves that may have fallen. I burned them, but you could toss them in the garbage--ANYTHING but leaving the fungus to reinfect. I saved my tree, which looks all hacked up this year, but has an abundance of new growth.
It happens when you have a lot of rain the spring and the fungus enters through the pear blossoms.

No blacken or dead branches yet. @w_r_ranch when should I spray ? @ducks4you NY springs are very wet.

Now I don't think it's fire blight. SO SORRY TO WORRY YOU!!!!! Please forgive!!
I'm batting zero this week. DD's went away, fed their two cats, only saw one all weekend--the two have been fighting lately--and I texted that something smelled dead under the porch.

Will it work now that it is infected?? Is it not more of a preventer?

when should I spray ?

ASAP. This will not 'fix' the damage already done, however it will stop it from spreading. Unchecked it will damage more leaves, causing them to drop. As mentioned earlier, clean up the fallen leaves & dispose of them by burning or in the trash. If you don't, the fungal spores will overwinter in the soil below the tree & in the spring these new spores are released to infect young leaves in a repeating cycle.

Remember, a severe leaf loss will ultimately weaken the tree allowing for additional problems.

Thank you will spray this week
