• Abstract: Carbaryl, fenpropathrin, deltamethrin and acetamiprid were evaluated for their ability to kill glassy-wing sharpshooter nymphs emerging from the egg mass under standard commercial nursery operations (including transportation). Carbaryl provided the best overall results resulting in near absolute control (98%) of emerging nymphs on all plant types (trees, shrubs, bedding plants). Fenpropathrin also achieved very good control. Control of emerging sharpshooters was poorest on bedding plants; this is largely due to the tremendous number of densely packed leaves within a small plant canopy and the resultant difficulty in achieving adequate coverage of the insecticides.
