Grasshopper Reports

Over the past few days I have received several reports of large grasshopper populations in several soybean fields. Initially, grasshoppers tend to occur along field edges and areas near drainage ditches. No economic damage has been reported due to grasshoppers yet. But consider this an early warning to scout fields. There are no good thresholds established for grasshoppers in corn or soybeans. Generally consider treatment in pre-bloom soybeans if grasshoppers are present and 40% or more defoliation is encountered. When in the pod forming and pod filling stages treatment is recommended with 20% or more defoliation.
