Evaluating Fall Armyworm Thresholds in Whorl Stage Corn in Mississippi

Currently, Fall armyworm thresholds in whorl stage corn for the state of Mississippi are 100% infested plants before any insecticide treatment is warranted. Many have questioned the validity of this threshold. The purpose of this research is to research various infestation percentages in whorl stage corn and leaf loss as it affects corn yield. The paper addresses preliminary findings from 2016 research trials on how defoliation in whorl stage corn influences corn yield at various growth stages.
