Deodar Cedar Decline: Pest Identification and Diagnostic Resources

A Deodar cedar in Spartanburg, SC shows browning, needle drop, and "tiny fuzzy brown things" on branches. The owner has healthy Deodars nearby, suggesting a localized issue.

Differential Diagnosis

• Sawfly larvae: If needles are chewed/consumed.
• Mealybugs or aphids: If "fuzzy" structures are present—these are waxy secretions covering soft-bodied insects.
• Needle cast fungi: If browning follows distinct patterns with fruiting bodies.

Immediate Steps

Contact the SC Forestry Commission for a free forester visit. Two specific resources:

• Laurie Reid, Forest Health Specialist (state office)
• Spartanburg County Forestry Commission office

Links provided in original response. Soil-applied systemic (Bayer Advanced Tree & Shrub) controls aphids/mealybugs; contact insecticides target sawflies.

Key Insight

Proximity to healthy conspecifics rules out site-wide abiotic factors. The problem is biotic and treatable—accurate ID is essential.
