How to identify
- Fine stippling on upper leaf surfaces
- Fine webbing on undersides in heavy infestations
- Hard to see without a hand lens — look for moving specks
Damage: Bronzed leaves, drop, and reduced yield in heat waves.
Control methods
- Hose undersides of leaves; mites hate moisture.
- Reduce dust and drought stress; mulch helps.
- Avoid pyrethroid sprays that kill mite predators and worsen outbreaks.
