Timing of damage: V8 to R6
Type of damage: Leaves will be chewed away from the outer edges inward. Fresh silks will also be eaten.
Scouting: Estimate the level of damage and number of grasshoppers per square yard in five locations. Damage is typically greatest along field borders, but move beyond borders when scouting.
Economic threshold: In field borders, eight or more grasshoppers or 15 or more nymphs per square yard; within the field, three or more grasshoppers per square yard.
