Tomato russet mite (Aculops lycopersici)
Symptoms
Rusty-brown, greasy, or bronzed appearance on stems and leaves, typically starting from the lower parts of the plant and moving upward; leaves dry up, curl, and wither.
How to verify
Compare the photos above with the plant, and check the symptom description against the look-alike records below before acting. The source guide does not carry a separate laboratory verification note for this record.
Next step
Wash tools and hands after handling to prevent mechanical spread; isolate or remove heavily infested plants.
Product / label options
PRODUCT / LABEL OPTIONS: If thresholds are exceeded, apply registered miticides. Complete coverage of foliage and stems is critical.

P. persimilis: allowed / avoid
PERSIMILIS STATUS: AVOID / RESTRICTED. • AVOID: Spiromesifen (sterilizes predatory mites) & Sulfur (harms beneficials). Fenpropathrin is highly toxic to beneficials and bumblebees. • RESTRICTED: Mancozeb (damages egg-laying; 7-day pre-release interval); Emamectin benzoate (3-day interval).
Label matters
Active ingredients below are examples, not universal prescriptions. Confirm the diagnosis; use only products registered for tomato and the target problem in your country; and follow the current label for dose, pre-harvest interval, worker protection, compatibility and re-entry. Rotate IRAC/FRAC modes of action. When symptoms are uncertain, obtain a laboratory or extension diagnosis. Integrated pest management (IPM)—sanitation, resistant varieties, irrigation management, monitoring and biological control—should be the first line of defense.
