Leafhoppers

I was out scouting some alfalfa in Burlington County and was finding pretty significant leafhopper numbers. Some plants were showing yellowing, which translates into yield loss. Remember to continue scouting for leafhopper. Treatment is generally recommended when the number of leafhoppers in 100 sweeps is 10 times greater than the average stem height. For example in 6 inch alfalfa you would need more than 60 leafhoppers in 100 sweeps. Complete scouting and treatment information can be found in the Mid-Atlantic Field Crop Pest Management Recommendations.
