Turfgrass Scale

TURFGRASS SCALE (Lecanopsis formicarum)

turfgrass scale lawn damage


Adult scales are light tan in colour with a body that is about 5mm in size. They can be distinguished by two dark stripes running parallel down their back. The adults survive in the thatch layer of your lawn during the growing season. They may cause minor damage by piercing the crowns of grass with a stylet and sucking juices out of the plant.

Increased damage may appear from nymphs feeding off the grass, resembling that of the adult scales. They nymphs appear during the late spring into the summer. They look like pink pin head sized dots. They are frequently seen in large numbers clinging to grass blades. The nymphs are a nuisance. They can cling to your feet as you walk across the lawn.

Scale damage frequently resembles drought and nutrient deficiency symptoms. Large areas of your lawn may appear wilted with a yellowish brown colour, however, it will not respond to watering. Your local Weed Man Professional can make a proper diagnosis.

turfgrass scale life cycleLIFE CYCLE OF TURFGRASS SCALE

Scales survive the winter as eggs in a creamy coloured casing. Early in the spring the casings explode into a mass of white fluff. Within the fluff many young nymphs appear and begin feeding off the ruptured casing. After a few weeks these young nymphs emerge as crawling nymphs and begin to feed off grass blades during the heat of the day. If the problem is ignored your lawn may be weakened allowing weeds or crabgrass to fill in the damaged areas.
