Practical guidance to reduce mold in walnuts through smarter harvesting and irrigation.
This book explains how mold develops in walnut nuts and how farming practices influence quality and value. Based on field studies, it connects irrigation timing, picking order, and handling to the grades you can achieve at packing.
The work shows what causes mold, how mold appears on kernels, and why many nuts that seem sound at harvest become culls later. It also covers different types of “stick-tight” nuts and how irrigation and harvest timing affect their mold levels. Readers will find clear recommendations for managing the orchard, speeding harvest, and sorting nuts to protect overall crop value.
- Understand how mold develops on walnuts from the tree to the curing yard.
- See how late-summer irrigation and harvest timing influence mold percentages.
- Learn practical steps to separate or husk problematic nuts before they degrade the crop.
- Get results-focused guidance for improving grading outcomes and packing outcomes.
Ideal for growers, extension readers, and students seeking concrete, field-tested strategies to protect walnut quality.
