Warhead Trio Broadleaf Herbicide 10L

Product Description

What is Warhead Trio?

Warhead Trio is a ProForce-brand herbicide manufactured by Indigo Specialty Products, containing 300 g/L MCPA and 20 g/L clopyralid (both present as the potassium salt) plus 15 g/L diflufenican. It’s a Group 1, 2, 4 herbicide for the control of certain broadleaf weeds in turf.

Who it’s for

Trade users and larger properties managing broadleaf weeds across established turf — the 10 Litre size suits commercial lawn care, turf management or larger residential properties rather than a single home lawn.

Why it works

MCPA and clopyralid are selective herbicides that disrupt broadleaf weed growth hormones without harming turf grasses when used as directed, while diflufenican adds residual activity. Apply as specified in the product’s Directions for Use for control of certain broadleaf weeds in turf.

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.
