Timing of damage: VE to R8
Type of damage: Adults skeletonize leaves. Larvae feed on roots.
Scouting: Examine five plants in five locations to determine percentage of defoliation.
Economic threshold: In V stages: 40% defoliation. R1 to R5: 15% defoliation. R6 to harvest: 25%
defoliation and beetles are actively feeding.
