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.

Winter Grass

Winter grass (Poa annua) is a soft, tufty light green grass that is usually noticed when it produces masses of creamy coloured seed heads during 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.
