Symptoms

Although tiny, whiteflies are clearly visible on plants, and you will easily be able to make an accurate diagnosis if these pests have infested any of your ornamentals -- just think “flying dandruff.” As the pests suck juices from plant leaves, buds, and stems the plants weaken, and the leaves turn yellow and die. Fruit and leaves may be covered with shiny, sticky honeydew, and a black sooty mold fungus may grow on the honeydew. Fruits may be undersized and poorly colored.
