So, I’ve had this tree 3 years and except for the year I planted it, it has had the same leaf spots. The fruit itself has no damage at all.
Because of the whitish leaves, I hit it with a high N urea mixed in a 5 gal bucket of water but there was no improvement.
Is it fungal?
That is caused by an iron deficiency. It is text book symptoms. Iron by itself wont correct the issue. “Chlorosis can be corrected by applying iron and manganese”. Make sure manganese is not applied directly to the soil. If it was my pear i would also apply epson salts for magnesium once right now. I would apply a foliar spray asap of iron and maganese. Add epson salt mixed with water around the plant about a foot or so away from the trunk.
Does the lack of iron typically affect pear more than other fruits? I have apple, peach, cherry, fig, nectarine that aren’t affected
No it doesn’t. Sometimes excessive water or root damage etc. can present the same symptoms. The chlorosis should respond to the foliar spray. A friend once applied epsom salt aka magnesium to his rosebush that was growing in heavy clay and the leaves turned from yellow to dark green correcting the issue. The wasps that had been feeding on the rose stopped.
I’ve used “Southern Ag Chelated General Purpose Flower & Garden Nutritional Spray” before as a foliar spray, but only once a year if I see leaves are yellowish and suspect a deficiency. It’s has a broad ingredient list.
CONTAINS: Iron 2.75%, Manganese 1.00%, Zinc 0.50%, Magnesium 0.50%, Copper 0.25%, and Sulfur 3.8%. USE ON: Flowers, shrubs, trees, vegetables and lawns CONTROLS: Minor element deficiencies, yellowing of foliage, etc. NOTE: Deficiency symptoms can be caused by improper soil pH. RATE: Foliar: 1 tbs. per gallon of water
I have just a few pear trees they start out kind of looking like this (black patches on the leafs) but they quickly grow out of it.
I was thinking it was caused by as too much water at the beginning of spring during leaf budding. However, reading this thread makes me think adding magnesium (epsom salt) to the soil would help? Probably wouldn’t hurt none?
Yes it looks to me like some magnesium would benefit your pears. I would add some. You would only know for sure with a soil test.
Thanks @clarkinks 
I’ve yet to get the soil tested. Been meaning too, just haven’t got around to it yet.
Someone turned off the sky water, so I need to water anyways. I’ll go ahead and add epsom salt to the water when I water all the trees
Fixing to hitch up the buffalo and add 100 gallons of water. If I recall correctly, I think normal epsom salt application is like 1 tablespoon per gallon of water. So that’s about 6.25 cups, sound about right for 100 gallons of water?
Thanks
@clarkinks Thanks, looks like I’ll need a trip to dollar general, because they are everywhere out here in the country 
None of my other fruit trees are affected but I agree it looks like iron chlorosis. The only thing i could find over here in Italy was an iron sulfate powder. I will try that
If you cannot find iron that should work. Read through this it will help How To Add Iron To Soil Naturally - AGreenHand
I forgot to say that I mixed powdered sulfur 1:1 with the iron sulfate, mixed it in water and poured it around the tree.
I’m going to get some Epson on Monday. How much do you use?
In your case i would use 2 tablespoons per gallon once.
I thought it only right to post a picture. After 6 days of an application of 2 tablespoons epsom salt and 1 tablespoon regular unscented anomia per gallon of water. applied to soil around this Moon Glow pear tree picture. My opinion it’s looking a lot better. Thanks @clarkinks
Before epsom salt and nitrogen ground application
6 days after
I also ordered a gallon of Southern Ag Chelated General Purpose Flower & Garden Nutritional Spray, it came in today and I’ll pick up another 2 gallon pump sprayer and apply it as directed in a few days. Thanks @sockworth
I applied the epsom salt to the pear tree…let’s hope it helps
