Description
How Kamba M Herbicide works
Kamba M Herbicide is formulated with two complementary synthetic auxin herbicides, dicamba and MCPA. Once absorbed through a plant’s leaves, these chemicals mimic plant growth hormones and disrupt cell division, causing uncontrolled growth (e.g., twisting and distortion) and eventually, total death, in susceptible broadleaf weeds. Crucially, most turf grasses are tolerant to both dicamba and MCPA, which makes Kamba M naturally selective and only effective against unwanted broadleaf species.
Why Kamba M’s dual-active approach is so effective
A selective broadleaf herbicide for turf, Kamba M relies on dicamba and MCPA to control critical weeds whilst leaving other desirable plant species unharmed. What makes it so effective is its dual-active approach.Â
Dicamba excels at controlling tough, deep-rooted perennials (e.g., docks, thistle, oxalis), while MCPA is highly effective on fast-growing annuals (e.g., capeweed, chickweed, bindii). Together, they deliver broader-spectrum control than most single-active herbicides and reduce the risk of resistance development.

Which desirable plants or grasses can’t Kamba M be used on?Â
Critically, Kamba M must not be used on buffalo grass, lippia, or strawberry clover, as severe damage or total plant death will occur. When applied to Kikuyu, carpet grass, or Queensland blue couch, transient yellowing may appear but these grasses tend to recover quickly.
Getting the best results out of Kamba M Herbicide
If you’ve selected to use Kamba M Herbicide in Australia, keep these top tips in mind for getting optimal results from your application:
- Spray your lawn when weeds are young and actively growing
- Do not mow turf for at least 2 days before or after application
- Do not spray within 4 hours of rainfall or general watering
- Do not spray when weeds are wet with dew or rain
- Do not spray if soil fertility is low or if the soil is waterlogged
- Avoid spraying weeds under stress (e.g., heat, waterlogging)Â
- Ensure thorough wetting of all weed foliage
- Do not fertilise turf for 2 weeks after spraying
- Do not allow grazing stock onto the sprayed area for 7 days after application
- Keep domestic animals off the treated area until the product has dried
Frequently asked questionsÂ
Is Kamba M safe for couch and Kikuyu lawns?
Yes, Kamba M Herbicide is safe for use on common couch, couch hybrids, and Kikuyu. Note that when applied to Kikuyu, some signs of transient yellowing may appear, but this is temporary and grass will recover quickly without permanent damage.
Why choose Kamba M over non-selective herbicides like glyphosate?
While glyphosate is a powerful herbicide, it kills everything in its path – weeds and grass. Kamba M, on the other hand, is selective, meaning it only targets broadleaf weeds whilst leaving your turf unharmed. This makes it an ideal choice for established lawns, sports fields, and golf courses where land managers are seeking weed control without total destruction. It’s very possible to spray and maintain a healthy, green lawn even while actively applying Kamba M.
Will Kamba M kill bindii (bindi-eye) in lawns?
Yes, Kamba M is a highly effective bindii weed killer for lawns. For best results when targeting bindii (Soliva sessilis), spray Kamba M Herbicide in late winter to early spring (August to September) before spiny seed heads form. Young, actively growing bindii plants are the easiest to control.
Can I use Kamba M on Buffalo grass?
No, buffalo grass is extremely sensitive to Kamba M, and will suffer severe damage or death when it comes into contact with the chemical. Never use this product on buffalo lawns – instead, look for buffalo-safe herbicides specifically labelled for addressing weeds in these varieties.
How does Kamba M compare to Bin-Die and other bindii killers?
Compared to single-target bindii products, most of which only rely on one active ingredient, Kamba M offers broader-spectrum control. While Bin-Die focuses specifically on bindii, Kamba M controls over 50 broadleaf weeds, many of which co-occur with bindii. This makes it a much more versatile and cost-effective option for lawns with multiple weed problems. The dual-active formula also reduces resistance risk compared to single-active products.

I had penny wort through my lawn and gardens. Roundup and weeding made it grow stronger until I discovered Kamba M. It’s all gone. I may get one or two here and there but I just hit them with Kamba M and I am now penny wort free.
