Rugose Spiraling Whitefly

Rugose Spiraling Whitefly (RSW) produces “honeydew,” a sugary substance that can stick to your house, car, or patio and make a real sticky mess. Leaves or fronds may have excessive and unattractive dark sooty mold that grows on the honeydew. Leaf drop may occur in some species of trees and plants.

Symptoms

whitefly infestation

An infestation of Rugose Spiraling Whitefly is generally easy to spot due to the sticky "honeydew" the insect produces. Black sooty mold may also grow on the honeydew, drawing further attention. The most obvious sign of an infestation is seeing the flies themselves as well as the white spiraling patterns they make on the bottoms of leaves, which may look like dust.

Treatment

Arborjet recommends a treatment with IMA-jet or AzaSol to combat Rugose Spiraling Whitefly. The TREE I.V. or QUIK-jet methods may be used, especially in combination with the palm injector kit for palm trees. IMA-jet works quickly throughout the tree's vascular system to deliver results within 3-4 days of treatment.

Why trunk injection?

  1. Fast Acting: Formulation is injected directly into the tree's transport system and is quickly distributed throughout the tree
  2. Effective: Proven by university trials
  3. Environmentally Responsible: Treatment is sealed in the tree
  4. Long Lasting: Trunk injection provides season-long protection

When to Treat

Generally, the best seasons for injection are fall and spring, as uptake occurs when trees are transpiring. The environmental conditions that favor uptake are adequate soil moisture and relatively high humidity. Soil temperature should be above 40 degrees F but no more than 90 degrees F for trunk injection. Hot weather or dry soil conditions will result in a reduced rate of uptake, so trees should be watered if applications occur when soil is extremely dry. Extra caution must be taken when treating trees in hot conditions, as doing so may result in an adverse reaction for the tree. Tree health will also affect treatment efficacy, so assess tree health prior to treating. For example, a declining tree (>50% canopy dieback) is a poor candidate for treatment.

What to Expect After Treatment

Trunk injections of IMA-jet for Rugose Spiraling Whitefly should act quickly to knock down the current infestation. We recommend spraying the undersides of leaves with a steady stream of water to remove the spirals and any remaining insects.
