Table of Apple Cultivar Susceptibility to Bitter Rot

Apples August 21, 2011 Print Friendly and PDF

 

Bitter rot is a fungus disease that causes fruit rot during the summer and the preharvest period. The bitter rot fungi are almost worldwide in distribution and cause an especially economically important disease in the southern United States. Outbreaks can occur rapidly, and losses can be severe, especially under prolonged warm, wet weather. This table lists the bitter rot susceptibility rating of many popular apple cultivars.

zMR = moderately resistant. Specific control needed under high disease pressure.
S = susceptible. Control usually needed where disease is prevalent.
HS = highly susceptible. Control always needed where disease is prevalent. These cultivars should receive first priority when control is required.
