Green Leafhopper
Small green leafhoppers causing hopper burn, yellowing and reduced vigour.
Green leafhoppers (Empoasca spp.) are small, active sap-feeding insects that move quickly and jump when disturbed. They cause hopper burn, yellowing, leaf margin necrosis and reduced plant vigour. They can occur on fruit, ornamentals and protected crops. Biological control uses generalist predators such as Orius spp. and predatory mites, supported by weed control and avoidance of excessive nitrogen.
Biological Controls for Green Leafhopper
