gardengal48; thx for reply.

Looked up scab and bitter pit. From descriptions not either of those. spots are less than skin deep. back side of apple peel shows no discoloration where spots are. Ditto for lenticel breakdown; spots do not get worse and become pits.

Mark in MN

Did you have a very wet growing season? Looks like mildew spots, just skin deep is not a problem.

Thx for comment. In general not particularly wet; my pond is lower than usual. However, we did have a couple of weeks wetter than usual at the end of the summer so maybe that's all it took.

sooty blotch imo

It sure looks like sooty blotch to me. Don't feel bad. If so it will only be on the skin so the flesh will be fine. actually if you polish them with a dry cloth or scrub with water before eating about 75% of sooty blotch will come right off.

I has sooty botch this year (first time ever) and I do spray with Captan diligently. The problem for me was my last spray was early August. I wanted one more spray late August but the weather did not cooperate (rain for the last 2 weeks in August). My bartlett pears were coated with sooty blotch when I picked them in early September. First time I had blotch on pears.

MSU put out a warning on sooty blotch for Michigan growers in late August due to all the rainy weather. It appears WI and MN suffered from the same results of all the rain as well.

You mention you sprayed with triacide. That will not help as this is a fungal not insect issue. A preventative fungicide spray is normally the best answer. With all the rain we got not sure if it would have helped much as we got 2.5" rain in one week and almost 3" the following week in late August. Normally an inch of rain or more will usually wash off so much fungicide that it would not work anyway on prevention and would have to be re-applied. I would blame your problem on the terribly wet weather in the upper mid-west

we got in late August and all of september so far.

Calcium Chloride applied as a foliar spray, will help with the lenticil splotch, A few times like 3 or 4 through-out the growing season
