This field was hit hard by potato leafhoppers. Many entomologists consider potato leafhoppers to be the most significant economic insect threat to profitable alfalfa production.
Growers scouting for potato leafhoppers infestations, which usually start to increase by early June, have another weapon in their arsenal. It’s a newly published pest profile.
The eight-page document is entitled Potato Leafhopper Ecology And Integrated Pest Management Focused On Alfalfa. It offers up-to-date information on the biology, life cycle, injury, hosts and management options for this alfalfa pest. Scouting, economic thresholds and foliar insecticides, as well as cultural control options and host plant resistance, are also included.
The profile was put together by a team of entomologists from the University of Wisconsin, the Illinois Natural History Survey, and USDA-ARS. Photos of the pest and damage are a part of this resource package.
