SureFire Dicamba M Selective Herbicide 5L – Dicamba Lawn Weed Killer for Broadleaf Weeds in Turf

Selective Weed Killer for Broadleaf Weeds in Turf

SureFire Dicamba M is a selective herbicide that kills broadleaf weeds while leaving suitable grasses unharmed. It combines 340g/L MCPA and 80g/L dicamba, both as the dimethylamine salt, in one concentrate. As a dicamba herbicide, it is registered for the control of certain broadleaf weeds in winter cereals, pastures, turf and non-crop areas. This 5L pack suits large home lawns, sports fields, golf courses, parks and rural properties, where a targeted weed killer is needed rather than one that kills everything it touches.

What Weeds Does Dicamba Kill?

Dicamba M controls a wide range of broadleaf weeds in all states, including:

• Bindii (bindy-eye), capeweed, cats-ear and chickweed
• Clovers, cotula, creeping oxalis and cudweed
• Dandelion, dock, fleabane, fumitory and Jo-Jo (onehunga)
• Lamb's tongue, medics, mustard and narrow-leaf plantain
• Pearlwort, pennywort, peppercress, radish and scarlet pimpernel
• Thistles, toad rush, wild turnip and wireweed (hogweed)

In Queensland, New South Wales, Tasmania, South Australia and Western Australia, the label also covers fat hen, purple top, red-flowered mallow, staggerweed and swinecress. It targets broadleaf weeds only, not grassy weeds.

Lawn Weed Killer That Spares the Grass

Used as a lawn weedkiller, Dicamba M removes bindii, clover, dandelion and other broadleaf weeds from couch, kikuyu and other suitable grass types, so you get a lawn and weed killer in one targeted spray. That makes it a practical weed killer for grass lawns, golf greens, bowling greens and sports fields. Dicamba for lawns must be matched to the right grass, though. It is not suitable for broadleaf turf varieties such as buffalo, which can be damaged, so always check the label for your turf type before spraying.

Two Actives: MCPA and Dicamba

Dicamba M is a Group I herbicide that combines two hormone-type actives. MCPA and dicamba mimic natural plant growth hormones in broadleaf weeds, causing uncontrolled growth, twisting and collapse, while most grasses are tolerant. Pairing the two gives this dicamba weed killer a broader spectrum of weeds than either active alone.

Pastures, Winter Cereals and Non-Crop Areas

Beyond turf, Dicamba M is registered for certain broadleaf weeds in winter cereals and pastures, and for non-crop areas such as fence lines, laneways and industrial sites. Follow the crop stage, rate and grazing directions on the label for these uses.

How to Use

Read the full label and attached leaflet before use. For small to medium turf and garden areas, the label rate is 100mL of Dicamba M in 15L of water, sprayed evenly over 150 square metres. Spray when weeds are young and actively growing, on a calm day to avoid drift. Keep the spray away from garden beds, vegetables, shrubs and trees, as broadleaf plants are sensitive to dicamba and MCPA. Avoid mowing for a few days before and after spraying so weeds have enough leaf to absorb the herbicide. Do not use on buffalo lawns.
