Fields should be sampled every 7-10 days. Each time the net passes in front of you is considered one sweep. Analysis Use of the sequential sampling plan will indicate the presence of an economic population. Early harvest of alfalfa can be effective in controlling economic populations. Green-chopping in strips is a poor management practice.
Chemical control is sometimes necessary when economic populations occur early in the cutting.
Consult the current Cornell reccomendations for potato leafhopper larval control. Implementation Treat only fields with a canopy adequate for spray reception. Clean harvest whole fields to eliminate harborage sites. Document allactions taken. Reevaluation Recheck fields after harvest to determine population status.
