How to Manage Pests
Pests in Gardens and Landscapes
Molds may start to invade the nuts in midsummer if the husks have been damaged by sunburn, drought,
or husk fly; damaged husks adhere to the shell and allow the mold to penetrate into the kernel, usually
through the soft suture. The chance for mold infestation increases rapidly once the husks start to split.
Mold develops rapidly under warm, moist conditions. Whitish gray mycelia form on the surface of the kernel
and often bluish green to grayish black spores, depending on the mold species.
To prevent contamination by molds as much as possible, protect the husk from damage and harvest and
dry the nuts rapidly.
