Zylam Liquid Systemic Insecticide can be applied as a soil drench, soil injection, bark banding, foliar spray and broadcast spray treatments for insect control in landscape ornamental plants. The label does not give instructions for injecting into the actual tree or plant. We would recommend contacting the manufacturer to confirm if this product can be used in that application, PBI Gordon can be reached at 800-821-7925.
