Herbicide

Get on top of weeds before they take over — glyphosate for total knockdown, selective herbicides that leave your lawn untouched, and pre-emergents that stop the next flush before it starts. Whether it’s bindii in the buffalo or woody weeds along the fence line, there’s a product here sized for a backyard spray or a full drum for bigger jobs.

Selective (lawn-safe) and non-selective (total-kill) options
Pre-emergent and post-emergent control
Pack sizes from 250mL trigger packs to 20L drums

Frequently Asked Questions

What is the difference between a selective and a non-selective herbicide?
A selective herbicide kills target weeds while leaving desirable plants unharmed – for example, a lawn-safe product that removes bindii and clover from buffalo or couch without damaging the turf. A non-selective herbicide such as glyphosate kills almost any green plant it contacts, so it is used for driveways, fence lines, garden-bed prep and total vegetation control, never on lawns.

What is a pre-emergent herbicide and when do I apply it?
A pre-emergent creates a barrier in the top layer of soil that stops weed seeds from establishing as they germinate. It does not control weeds that are already growing. Apply it before the target weed germinates – late summer to early autumn for winter grass, and early spring for summer grasses like crabgrass and crowsfoot – then water it in.

Will herbicide damage my lawn?
Only if you use the wrong type. Non-selective herbicides (glyphosate) will kill or badly damage turf. Selective lawn herbicides are formulated to be safe on common Australian turf at label rates, but tolerance varies by grass – buffalo is the most sensitive – so always check the label lists your turf type before spraying.

How much herbicide do I need for my area?
Most concentrates are mixed at a set rate per 100 square metres or per 100 litres of water, listed on the label. As a guide, a 250 mL to 1 L pack suits a home lawn or garden, a 5 L pack suits a large block or acreage, and 20 L drums are for commercial and broadacre use. Buy the size you will use within the product shelf life once opened.

How soon can it rain after spraying?
It depends on the product. Many systemic herbicides need a rain-free period of one to six hours to be absorbed; some newer formulations are rainfast in under an hour. Spraying dry foliage on a still day with no rain forecast gives the most reliable result. The label states the specific rainfast period.
