Interpretive Summary: Excessive fruit abortion is a major industry-wide problem for pecan producers. Abortions occur due to a variety of reasons that can be controlled by orchard managers. An overview is provided describing the types of abortions and their causes. The primary causes are low tree resource reserves from the previous growing season and failure to achieve egg fertilization due to pollen associated problems. This information provides producers with the background information needed to adjust orchard management strategies to minimize fruit abortion and to subsequently increase orchard profitability.
