Pest: Siphorinus phillyreae
Symptoms
White appearance in patches on lower surface of leaf in initial stage of infestation.
Control
Management of heavy whitefly infestations is difficult.
Remove infested leaves or hose down with water sprays.
Insecticidal soaps or oils such as neem oil may reduce but not eliminate populations. Systemic insecticides may be more effective but can have negative impacts on beneficial insects and pollinators.
