Leaf hoppers are yellowish in colour and around 2mm to 3mm long. As their name suggests they (the adults) will jump off if their plant home is disturbed. The immature nymphs are creamy white and crawl. Both nymphs and adults feed on the sap of plants.
Colonies on the underside of leaves will have up to 3 generations present at any one time. Leaves will become gradually paler with white surface mottling.
Treatment and control
Spray with a natural-based insecticide: Pyrethrin (a natural plant extract) based insecticides will control Leaf Hoppers and other plant pests. An example is BugClear Gun! for Fruit & Veg. For best results spray thoroughly.
Spray with a general insecticide: Most broad spectrum insecticides will control Leaf Hoppers. Examples are BugClear Ultra Gun! and BugClear Ultra. They kill very quickly on contact and also have a residual effect which lasts for a few days.
