Dwarf Yaupon Holly: Spider Mites + Whiteflies Dual Infestation

Two Pests

Miticide Options (Mites)

• Dicofol (Kelthane) – best but scarce.
• Horticultural oil + insecticidal soap rotation – practical.
• Predatory mites – biological.

Insecticide Options (Whiteflies)

• Contact: Acephate (Orthene/Isotox), Malathion, Permethrin, Bifenthrin – 3× at 7-day intervals.
• Systemic: Imidacloprid (Merit/Bayer Advanced) soil drench – best for sustained control.
• Old systemic: Disyston (granules) – toxic, restricted.

Integrated Plan

1. Horticultural oil spray (covers both pests initially).
2. Imidacloprid soil drench (systemic whitefly control).
3. Monitor; spot-treat mites with oil/soap as needed.

Autumn recurrence = overwintering populations. Early spring oil + systemic drench breaks cycle.
