Favourite pear. I referred the photos to NAFEX but got no response. My
infected pears rarely develop beyond one inch in diameter. They just go
black and shrivel up. I recall opening the infection and vaguelly recall a
small larva - but could find nothing on the INet - hence the NAFEX message.
This has occurred again this year; 90% of the pears are gone. Last year, I
had a good crop. I do have occasional splitting in some of the pears, but
nothing consistent.
The picks for the black spots are #'s 7, 8 and 9 on the Photobucket link. A
split line may be seen in photos 4 and 5.
