Top 10 garden weedkillers

Updated on July 6, 2009

Top Weedkillers

If you do gardening you definitely need them or in other way i should say that if you know weeds you know them. In this hub i would like to talk about Round up, vigilant, turfix, escort, DAS, Prefix, Hydrocotyle, Woody weedkiller, Pulse Penetrant and Amitrole. You may be aware of some of them or may be not but i think that this information can guide you a little bit while you go to buy weedkillers.

These weedkillers are sold by Yates, Mcgregors, watkins, Kiwicare and other popular brands but as you do not know about actual chemical in them you just go and ask the brand and pay for it.

 Whenever you go to market to buy any weedkiller, you just know the brand name and go and buy any branded weedkiller but do you know that if you know the active ingredient (chemical that actually works) of these weed killer you would be actually paying very less money. So to save money you should know the active ingredient or lets us take it otherwise if you know what chemical control what sort of weeds than you do not need to pay for the brand.

Knowledge is very powerful and it can save money as well because there are lot of brands that make the same chemcial with different names and the only thing you are paying is the label on the bottle, so stop paying for the label, start paying for the chemical.

i will discuss one by one the active ingredient and tell you what you can use it for.

360 g/litre glyphosate as the isopropylamine salt in the form of concentrate liquid

Also Known as: Round Up, Watkins commercial weedkiller, 360 degree, Total control etc


Controls: It is a broad specturm weedkiller. it effectively controls broadleaf weeds, grases and other difficult to control weeds. it is a non selective herbicide so be careful not to spray on desired plants.

The best thing about is that it has a very less soil life so that it is safe to use in garden beds, rockeries, driveways, along fencelines and lawn edges, around buildings. It is absorbed through the foliage and moves in system of plant, killing both treated foliage and root system of plant.


Also known as: Yates Amitrole, Mcgregors Amitrole


Controls: It is mostly used to control bamboo. It also controls broadleaf weeds, cape ivy, wandering jew, wild oninon, docks, sheeps sorrel, mercer grass and periwinkle, couch and indian doab.

A mixture of 400g/litre simazine, 125g/kg amitrole and 257g/kg 2, 2-dichloropropionic acid in the form of a wettable powder

 Also known as : DAS


Controls: It is a mixture of three different chemicals which gives a long term protection against the broadleaf weeds and grasses up to 12 months once sprayed. It has a long soil life so it is best to use on driveways, patios, and othe path ways.

A mixture of 100g/litre 2,4-D and 50g/litre dicamba, both as amine salts, in the form of a soluble concentrate

Also known as : Woody Weedkiller, Mcgregors weed out


Controls: It is a selective hormonal weedkiller that controls broadleaf weeds. it is more targeted on woody scrub weeds, convolvulus, docks, sorrel, cape ivy, thistles, buttercups and re sprouting tree stumps (willow, poplars, tree privet). It can be used on broadleaf weeds in lawns.

67.5g/kg dichlobenil

 Also known as : Prefix D

Controls:  It is also a long term weedkiller controlling broad leaf weeds and grasses. it also prevents germination of weeds up to one year.

It comes in the form of granules so it is easy to use. The best place to use this is along the driveways, patios, pathways and near building where you will not be planting anything as it remains active in soil for a longer time.

120g/Litre triclopyr

Also known as: Hydorcotyle, No hydorocotyle (by Kiwicare) a lot cheaper

Controls: It is a selective weedkiller for the control of hydrocotyle, creeping oxalis. it also controls broadleaf weeds (including daisies and clover) in grass lawns.

It is a mixture of 200g/litre mecoprop, 50g/litre MCPA and 6.2g/litre dicamba as the dimethylamine salts in the form of a soluble concentrate

Also known as: Turfix

Controls: It is a selective herbicide used to control broadleaf weeds, daises, onehunga weed, catsear, chickweed, chamomiles, docks, thistles and dandelion.

It does not harm any grass or lawn so you can use it in your lawn

It contains an organo-silicone copolymer penetrant and surface active agent.

Also known as: Pulse Penetrant

Although this is not a herbicide but i have put it here because it helps the weedkiller to penetrate the leaves and hence increases the effectiveness.

Sprayfix or spraystick are cheap alternative to this but they only help the weedkiller to stick to the foliage of the plant whereas pulse penetrant helps the weedkiller to go inside the weeds and hence increases its effectiveness

Vigilant is available in a 240 gram brush bottle, a 1.8 kg refill pack, and a 20kg pail with pump
Vigilant is available in a 240 gram brush bottle, a 1.8 kg refill pack, and a 20kg pail with pump

Also known as: Vigilant or Picloram


Agapanthus (Agapanthus praecox)

• Climbing spindleberry (Celastrus orbiculatus )

• Cotoneaster (Cotoneaster simonsii )

• Darwin's barberry (Berberis darwinii )

• Elaeagnus (Elaeagnus x reflexa )

• Kahili ginger (Hedychium gardnerianum )

• Old Man's Beard (Clematis vitalba )

To control these weeds, they need to be applied in a specific manner. i have provided a link which will help you to know more about this product.

It works best as a post emergence herbicide (once the plant has germinated). It can be used on conifers and other hard to kill trees.

Although it is very expensive herbicide but it is very effective as well.
