Summary: This webcast reports the results of research on early season hail damage, which can affect a number of field parameters later in the season. Nearly all hailstorms occur during the first half of the growing season and therefore early in the development of corn plants. Multiple time-sensitive factors must be considered in assessing the yield potential of the damaged field and deciding whether to replant. In addition to physical damage, the potential for diseases such as Goss’s wilt to develop because of open wounds in plants must be considered. Future research with a new simulated hail machine will focus on opportunities to standardize applications.
