Cutworm

Cutworm

Situation: A number of Cutworm species are known to damage turf grass. The periods of activity of cutworm species are winter and early spring (common cutworm), late summer and autumn (cutworm) and mid-spring, summer and early autumn (brown cutworm). The larvae are inactive during the day when they live in vertical larval holes in the soil. 

Occurrence: Damage by cutworm larvae occurs at night when they come out to feed on bowling and golf greens. The symptoms appear as circular spots up to 5cm in diameter, devoid of foliage.
