Whiteflies

Symptoms

Infested leaves often have small, yellow spots where feeding occurred; with high infestations, leaves become yellowed and leaf undersides are covered with sooty mold.

Management

If necessary, spray the shrub thoroughly in mid-summer when adult viburnum whitefly begin to appear. Use thiacloprid (e.g. Bayer Provado Ultimate Bug Killer), acetamiprid (e.g. Bug Clear Ultra) or deltamethrin (e.g. Bayer Sprayday Greenfly Killer) or pyrethrum (considered organic e.g. Py Spray Garden Pest Killer).
