Manage My Recovering Crop
Please take a moment to share your feedback with the Hail Know Team. Take our survey
Hail damage to plants can increase the likelihood of inoculation of some plant pathogens and infestation of some insect pests. These organisms can increase yield losses and, in some cases, make grain unmarketable.
Hail can strike late enough in the growing season that replanting isn’t a feasible option. This infographic focuses on several considerations for managing a recovering crop.
In addition to primary plant injury from hail, damage can occur later in the season from bacterial pathogens that enter plant wounds. This video addresses the potential for continued plant injury from bacterial disease and how best to manage harvest and grain storage. it also notes research showing that fungal pathogens do not cause additional injury post-hail.
Production loss estimates in corn from hail damage is a critical first step for determining the need to replant or to make adjustments on future inputs. Regardless of crop development stage, it is critical to wait 7-10 days to allow the crop to respond for proper evaluation. Production loss estimates by the Federal Crop Insurance Corporation in corn may include remaining plant stand, defoliation and direct losses from ear damage depending on the stage of development. Additional losses and quality issues can occur with fungal infections so continued scouting of hail damage fields is important. Be sure to contact your crop adjuster before making any management decisions on a hail damaged crop. Justin McMechan, University of Nebraska Crop Protection and Cropping System Specialist.
