Dear apple-croppers... Last year at this time of the year, we had a fun thread on a mystery apple. This year, I would propose one on a mystery disease... Hopefully it will trigger just as much interesting discussion! I have taken pictures showing the symptoms/damage. Please look here: http://picasaweb.google.com/cjoliprsf/AppleDisease2010 Let me give you a little information on this: - Pictures were taken on August 14 2010 - The size of the apples on the picture is about 1 inch across - The apples didn't grow any bigger during fall - All the apples show the same symptoms - There is only one tree affected in the orchard (a small 1 acre orchard) - Affected variety: Wealthy (there are other Wealthy trees around that are normal) - This appeared about 5 years ago and reappears every year on this particular tree - The affected apples ripen later than normal - actually, they don't really ripen, but they stay attached on the tree until snow. - The foliage is otherwise healthy and the tree normally vigorous - Other trees about 20 feet away do not show any similar symptoms Thanks for looking at this.
