Kernel Molds

Hazelnut kernels develop mold inside the shell, reducing marketability. Kernel mold fungi attack during storage or high-moisture conditions. Dry and store kernels properly at low humidity and cool temperatures. Harvest at the right time and avoid injury that provides entry points for fungi.

Cultural management is your first line: remove infected material, clean up debris, and improve the growing environment to make conditions less favorable for the pathogen. Avoid wounding plants during maintenance, as many pathogens enter through fresh cuts. Chemical options are available for severe cases, but they work best as preventive treatments applied before symptoms appear.
