Understanding Weedkillers


October is weed month and, with spring now well established, weeds are appearing all over the place. The first and simplest way to deal with weeds is to dig them out. Sometimes, though, the problem is so bad you need to resort to a weedkiller or, to use the technical term, a herbicide. Because different herbicides have different uses, it’s important to choose the right one for your purpose.

Selective Weedkillers For Lawns

Selective weedkillers remove one type of plant from another and are mostly used to get rid of weeds from a lawn. These weedkillers work by targeting the botanical differences between broad leaf (non-grass) weeds and the lawn grasses. Here are some examples:

Yates Bindii & Clover Weeder:

Yates BuffaloPro:

Weed ‘n’ Feed:

With all these selective weedkillers, it’s important to follow the instructions. That includes applying the product over the designated area. Apply too much and you can damage the grass, too little won’t do the job.

Non-Selective Weedkillers:

These are total weedkillers that kill every plant they contact. Clearly, this means that they can’t be applied to lawns and must be used with extra care.

Yates Zero is a glyphosate-based, total weedkiller. Zero’s available in a number of different sizes and can be purchased as a concentrate or a ready to use. The concentrate is particularly economical because of its strength (490 grams per litre), which means it goes a lot further when it is mixed. Glyphosate works by disrupting the plant’s growth and travels through the plant’s system and down to the roots before killing the plant. Depending on growing conditions, this can take some time so, for faster results, you can use the Zero Rapid version that comes in a trigger pack.

Once the weeds have gone, the area can be re-planted. If you want to be sure of where you’ve sprayed, add some of the Yates EasySee Spray Dye to the mix which will leave a blue covering on the sprayed sections for a few days and makes it easy to check if you’ve missed any weeds.

Yates Tree & Blackberry Killer is the product to choose for killing unwanted weedy trees, or bushy weeds like blackberry and lantana.

Another type of total weedkiller in the Yates range is called Path Weeder. Yates Once a Year Path Weeder leaves a residue in the soil that stops new plants from growing for up to twelve months. So it’s obviously not the product that you use in garden beds or anywhere you want plants to grow, but it’s ideal for driveways, courtyards and areas like tennis courts.
