Fruit Disease Fact Sheets
This site provides information on the common diseases of apple, grapes, small fruit (blueberry, strawberry, brambles), pear, and stone fruit (peach, plum).
For more information on fruit diseases as well as the entire fruit production process, see the online guide called "Fruit Production for the Home Gardener". You can also order a print version of the guide for $12 plus shipping. This is a wonderful resource for people who wish to produce fruit on a small scale and are not legally licensed to use pesticides.
