Pesticide control The RHS believes that avoiding pests, diseases and weeds by good practice in cultivation methods, cultivar selection, garden hygiene and encouraging or introducing natural enemies, should be the first line of control. Encourage predators and other natural enemies of leafhoppers, in the garden, such as birds, ladybirds, wasps and ground beetles.Often leafhoppers do not affect the growth or vigour of plants and so can be tolerated, they are part of the biodiversity a healthy garden can support.They have piercing sucking mouthparts to feed on plant. Pesticide treatments are likely to kill natural enemies and are only likely to be successful if the entire plant can be reached. Leafhoppers are small insects, generally less than 1/2-inch long, with hind legs modified for jumping. Normally leafhoppers are not noticed, unless one looks very closely at the grass blades. Their color is variable but many of the more common turfgrass species are generally light colored or brown. They are small insects, typically less than 1/6-inch and are slightly wedge-shaped. Within pesticides the shorter persistence products (that are usually certified for organic growing) are likely to be less damaging to non-target wildlife than those with longer persistence and/or systemic action. Leafhoppers can be common insects of lawns. When choosing management options you can minimise harm to non-target animals by starting with the methods in the non-pesticide control section and avoiding pesticides.
