Tulip Poplar Aphid Honeydew: Systemic Treatment for Large Trees

Mature tulip poplars dripping sticky honeydew (puddles on deck). Early spring, 5-week drought.

Cause

Aphids sucking sap, secreting honeydew. Sooty mold often follows (blackens foliage).

Treatment

Large trees = hard to spray. Use soil drench: imidacloprid (Bayer Advanced Tree & Shrub Insect Control). Roots translocate to canopy. Takes weeks to reach top; season-long control. Product Link
