Turfgrass-Leafhopper

Cicadellidae (several species)

Pest description and crop damage Slender, less than 0.25 inch long, green, yellow, or brownish gray insects that hop and fly short distances above the lawn surface. Feeding causes grass blades to look mottled or whitish.

Management-biological control

Research indicates larvae are not affected by endophytic fungi common in some varieties of perennial ryegrass, fine fescue, and tall fescue. Research in the PNW has indicated limited efficacy of beneficial nematodes. Biological controls in general have not been shown to be effective on this pest.

  • beneficial nematodes-Read label carefully for application procedures, timing and appropriate soil temperatures for best efficacy.

Management-chemical control: HOME USE

Reinfestation may occur from adjacent, untreated areas. Repeat applications may be necessary. Do not permit children or pets on the treated turfgrass until it has been watered to wash the insecticide into the turf and the grass is completely dry. Most insecticides are toxic to bees exposed to direct treatment or to residues on blooming weeds/ flowers in lawns: mow and remove clippings prior to applying insecticides.
