WSU-TFREC/Postharvest Information Network/Tree Fruit Market Diseases/Quinces (in general)



Quince production has been on the decline for many years. Losses caused by the oriental fruit moth (Grapholitha molesta Busck) in the middle Atlantic-coast States has probably eliminated production there. Some commercial plantings of quinces may be found along the northern fringe of commercial peach orchards where control of the oriental fruit moth on quinces has been effective. There is also an occasional planting of quinces in California.

Quinces are subject to many of the diseases that occur in the orchard and after harvest on apples and pears. Some of the most important ones are discussed.
