The website walks you through the process with videos and quick infographics that provide information on the hailstorm, assessing plant damage, handling insurance, and managing a recovering crop. HailKnow, a product of the University of Nebraska-Lincoln, is a one-stop shop for making informed and timely decisions after a hailstorm. "You can’t prevent hail, but it is critical that you assess the extent of damage to determine the best management practices for the remainder of the growing season," Justin McMechan, UNL crop protection and cropping systems specialist, commented. Hail damage to row crops can occur at any time during the growing season. Following the weather event, it was the TAPS team's decision to cancel the insecticide decisions due to the low pre-storm infestation rate and an expected decrease in egg masses due to leaf damage. Julie Peterson and her team scouted for western bean cutworms on July 21 and found 2%-3% infestation in the SDI plots. The only management decision that was affected by the storm damage was the insecticide decision in SDI corn. Therefore, there will be no insurance payment based on the hail damage instead, any indemnity payments will be based off the final yields at harvest along with the type and level of insurance coverage the participant selected at the beginning of the year.Īs for management decisions, competitors are still afforded the opportunity to apply late-season nitrogen fertilizer via fertigation, as well as irrigate on Mondays and Thursdays. The TAPS competitors are required to carry at least 65% multi-peril crop insurance, but no hail or wind insurance is offered. The popcorn competition was approximately one growth stage behind the other corn competitions and is estimated to have a similar yield loss range. Consequently, the estimated percent of corn yield loss is from 17%-31%. Therefore, it is estimated that there was approximately 35%-50% leaf defoliation. LAI is the ratio of one-sided leaf area per unit of ground area and is used to quantify the amount of leaf material in a canopy. The same data was collected on this research area following the storm with new values of 2.9 ft 2. The adjacent study had similar crop growth conditions with resulting values of 4.4 ft 2. Leaf Area Index (LAI) measurements were collected the week prior to the storm in an adjacent study located on the same variable rate irrigation sprinkler system. With those steps in mind, the TAPS team has determined that the TAPS sprinkler and SDI corn fields were averaging R1-R2 growth stage at the time of the weather event.
