Whitefly Control


-adults are winged fly-looking insects

-usually found on undersides of leaves grey to white (1.25- 2 mm long)

-plant sap is removed from the leaves and young shoots causing plant stunting and leaf drop
-excretion of honeydew, reducing photosynthesis and causing sooty mold to colonize on the leaves
-often a disease vector, ingesting virus particles when feeding and spreading them to other plants
