Nut Diseases

Kernel Discoloration (several fungi)

Key words: Several fungi, insects, drying

There are several fungi that have been associated with discoloration of pecan kernels. Certain insects (stink bugs) can cause kernel discoloration. Since delayed harvest can also cause this problem, do not allow pecans to lay on the ground for any length of time. Pecans should be dried before sacking and forced ventilation in storage is recommended.
