Bartlett Pear Webbing: Spider Mites or Mildew? Organic Solutions

Diagnosing the Webbing

Fine webbing on pear leaves with leaf drop suggests spider mites, not powdery mildew (which looks like white dust). Mites spin silk; mildew does not. Ants may farm honeydew from aphids, but webbing = mites.

Treatment Options

Atomic Grow: Organic systemic—cleans mites, heals foliage, boosts tree immunity.
Neem oil: Suffocates mites; repeat every 7–10 days.
Insecticidal soap: Good contact kill; thorough coverage essential.
Horticultural oil: Dormant or summer rates; smothers eggs and adults.

Avoid Malathion

Broad-spectrum organophosphates like malathion kill beneficial predators, causing mite resurgence. Reserve for last resort.

Tree Recovery

Pears tolerate defoliation if roots are healthy. Water deeply, mulch, and fertilize lightly. Monitor for new growth—recovery is likely with early intervention.
