Field Identification
Microscopic tarsonemid mite that distorts new growth—crinkled, hardened, 'bronzed' leaves and scarred fruit on peppers, tomatoes, citrus, and many ornamentals. Damage often appears before mites are seen.
Adults are nearly invisible without 15x magnification; eggs are pearly and studded on peppers. Feeding toxic saliva causes the characteristic downward cupping and narrow 'strap' leaves.
How to Deal With It
Organic Control Methods
Sulfur, horticultural oil, or soap—applied early at first distortion—can suppress broad mite; repeat on tight intervals because eggs are protected.
Neoseiulus cucumeris and Amblyseius swirskii predatory mites are used commercially in protected crops; outdoors, conserve generalist predators by avoiding unnecessary sprays.
Remove and destroy first symptomatic terminals; avoid moving infested transplants between houses; lower humidity extremes that favor tarsonemids in tunnels.
Nothing reliable besides exclusion in greenhouses—focus on biocontrol and sanitation.
Quarantine new plant batches; sticky tape on boots between houses; scout growing points with random leaf pulls.
