Plant Selection is Priority 1!!
Highly susceptible:
Most lindens Purple leaf plum Sassafras Norway maple Roses Certain crabapples Roses Hibiscus
Resistant:
Red maples Most oaks Flowering
dogwood Redbud Beech Hickory Tuliptree Sweetgum
Traps contain two lures: a floral scent, and the female sex pheromone
Traps were evaluated in home landscapes and on golf courses

Summary
• Pyrethroids (DeltaGard, Talstar, Scimitar, Tempo) gave at least 19 days’ residual protection; longer than Sevin
• Most “homeowner” organic products were ineffective
• Pyola® (pyrethrins & canola oil) and Neem-Away® deterred feeding for 3-7 days.
