Scale on Lilac Spread to Grass? Likely Rust Fungus, Not Scale

After removing scale-infested lilac, owner finds orange-brown dying grass under a crabapple, suspects scale spread. Asks for treatment.

Key Insight: Scale Don't Infest Grass

Scale insects feed on woody tissue, not grass blades. The orange color suggests rust fungus on grass.

Test for Rust

• Rub grass blades between fingers.
• Orange powder on fingers = rust spores.

If Rust Confirmed

• Mow and bag clippings to remove spores.
• Apply lawn fungicide if severe.
• Identify grass type: Bermudagrass and Zoysia are rust-prone.

If Still Suspect Insects

Respond with grass type and close-up photos for further ID.
