Eleven insecticides were evaluated against the threecornered alfalfa hopper, Spissistilus festinus (Say), the potato leafhopper, Empoasca fabae (Harris), and the tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), in alfalfa. Control of S. festinus was extended to 28 d post-treatment with a single application of cypermethrin applied to the alfalfa stubble. Control of E. fabae was achieved with the majority of the insecticides evaluated, but control of L. lineolaris was more difficult to obtain.
