Lawn Weed Image

Weeds, Pests and Diseases are something that will be part of your lawn’s life cycle. However there are ways to help prevent them from taking control.


Weeds are very easily dispersed, so are almost impossible to eradicate completely. A longer lawn, with a dense growth habit helps in outperforming weeds, while an aerated soil is a much better option than a compacted soil.

In saying this, weeds can be transferred on shoes, in manure, with animals, or even the mower. Common weeds such as dandelion, bindii, clover and creeping oxalis are all treatable. Some can be removed by hand but often a weed spray is the preferred and better option.

You need to check the suitability of the product you are using for the weed you are trying to remove. Some are not suitable for different varieties of lawn. 

Weed identification


Bindii is an annual weed which looks like a small ferny rosette about 20mm in diameter.


Marshmallow, dandelion, cat’s ear, lamb’s tongue, chickweed, plantain, fleabane and dock are some of the common broadleaf weeds found in lawns and home gardens.


Capeweed is an annual which starts appearing from February to about April.


Clover is a very common weed of lawns.


Dandelion is a perennial herb that has a very long tap root.

Moss Algae Lichen

Algae (a green or black scum) and moss are usually problems in shaded, over-wet or badly drained and compacted sections of the lawn and garden.

Onion Weed

Onion weed stinks and Yates can help rid your garden of this unpleasant weed. Known for its hardiness, we can help you remove it effectively with our products.


Creeping oxalis (Oxaliscorniculata) has tiny clover to heart shaped leaves that form roots wherever the stems touch the ground.


A tough perennial grass growing out from a central base or crown that is very difficult to pull out by hand when mature.


There are many varieties of thistle in Australia and New Zealand, of which Scotch Thistle was a declared a weed as far back as 1850. Thistles grow as a rosette of leaves close to the ground from which grow tall stems carrying the flowers.

Winter Grass

Tufty, soft, light green grass with masses of seeds occurring all over the weed that will eventually overtake the lawn in winter.


The most common lawn insect pests are curl grub (the larvae of beetles like the African black beetle) and lawn armyworm.

Curl grub eat grass roots just below the surface. The lawn can turn yellow, then brown and die, and the lawn can be rolled up like a carpet. Lawn armyworm are caterpillars that strip grass foliage, causing rapidly expanding bare patches. Other symptoms of curl grub and armyworm are birds pecking and scratching in the lawn.

Adult African black beetle and lawn armyworm can both be controlled by applying Yates Baythroid Advanced for Lawns. Apply Yates Baythroid Advanced for Lawns from late winter to late spring to control the adult African black beetle (before it has a chance to lay eggs) and in mid to late summer and autumn to control lawn armyworm.



Many common lawn diseases include brown patch and dollar spot, which appear as dying spots and patches of lawn.

Diseases can be more common in lawn areas with compacted or poorly drained soil, in shaded areas, areas that are damp overnight and underfed lawns. Only water lawns in the morning, so that the grass has the chance to dry before nightfall. Keep the lawn healthy and well fed to encourage disease resistance. The most common lawn diseases can be controlled with Yates Zaleton Fungicide.
