Pest on Meyer Lemon: Scale or Mites? Switch from Oil to Botanicals

Persistent pests on a container Meyer lemon (ovoid adults, clear/white egg clusters) with severe leaf drop after horticultural oil treatment suggest oil burn. Oil can damage foliage if overused.

Better Organic Alternatives

Pyrethrum or rotenone sprays: Effective, organic, can be applied liberally without leaf burn risk.
