In this case, taking a stand count of viable plants a week after frost will better reflect the yield potential of the field rather than using the defoliation chart. There are 3 factors which will affect final yield in fields which have had hail damage. The percent of leaf surface which has been lost. Decreased photosynthesis results. The stage of growth.
Small plants continue to grow new leaves replacing lost capabilities.
Extent of stalk and ear damage. Hail causes severe bruising on the stalk which can result in breakage or stalk rot. This affects the general plant health and late season standability. If the ear is damaged , there is a potential for ear molds to set in. Inc. All rights reserved.
