Following some issues with aphids and alfalfa weevil prior to first cutting, we now are moving on to a second major insect pest in alfalfa prior to second cutting and beyond, the potato leafhopper. Last year on June 15, we found potato leafhoppers using a sweep net during a site visit in Gage County on June 15. Though I have not had any reports yet this year, it is not too early to start scouting your alfalfa. Potato leafhoppers can cause tonnage and significant economic losses, so good scouting and timely management is justified.
