Interpretive Summary:

Technical Abstract: The Hagberg-Perten Falling Number (FN) method is used to detect starch degradation due to ''-amylase enzyme activity in wheat meal. Wheat can be severely discounted when the FN is below 300 seconds. Farmers in the northwest wheat-growing states suffered serious economic losses due to widespread problems with low Falling Numbers (FN) in 2016. This article discusses the roles of preharvest sprouting and Late Maturity Alpha-Amylase in triggering low FN, and discusses possible management strategies.
