Leaf Miner Control on Serviceberry: Systemic Insecticides and Sanitation

Why Sprays Often Fail

Leaf miner larvae feed inside leaves, protected from contact sprays. A systemic insecticide (e.g., Dimethoate) moves into leaf tissue and kills miners.

Timing and Sanitation

Spray when mines first appear (late April–early May). Rake and destroy fallen leaves to reduce next generation. Populations cycle yearly; treat only when damage is observed.
