Plaintain is common weed in turf especially once the soils has been disturbed and is moist. Flowers from mid spring through until summer.

Pythium Leaf Blight

Pythium Leaf Blight appears suddenly during hot, humid weather. Infected leaves become light tan to brown, shriveled and matted when dry.

Pythium Root Rot

Affected turf may appear thin, off colour and growth slows. It may occur in patches or as a general decline of large areas.

Red Thread

Dead leaves are interspersed amongst uninfected leaves giving an overall diffuse, scorched or ragged appearance to the patch.


Ryegrass is a cool season perennial grass with a tufted growth habit, glossy dark green leaves and resistance to many herbicides.

Seedling Damping Off

Damping Off appears as blighted seedlings. Individual seedlings are stunted with water soaked leaves.

Sod Webworm

Sod Webworm is a thick caterpillar up to 25mm long with a pale green-brown body that is marked with characteristic dark spots.

Spring Dead Spot

Circular patches of bleached, straw coloured dead grass appear in spring as the dormant grass regrows.

Summer Grass

Summer Grass will compete for nutrients and space against desirable turfgrass species or when turf is this and open.

Take-All Patch

Take-all patch symptoms begin as a slight reddening or bronzing of bentgrass usually in a ring in the summer months.


Thistle is an invasive species in some parts and infestations can quickly increase in density and can dominate vegetation.

White Clover

White Clover usually occurs in parkland and golf fairways throughout early winter and spring. It flourishes with heavy rainfall or irrigation.

Winter Fusarium

Circular patches appear as small. Water soaked spots less than 5cm in diameter. Patches change in colour.

Winter Grass

Winter Grass can establish itself at any time during the year but is prevalent in winter and spring. Also known as Poa annua.
