Choosing a Weed Killer

Selective weed killers or selective herbicides are chemicals that are used for the control of weeds in lawns and turf. These weed killers only kill broad-leaved weeds, they do not harm the grass, hence the name ‘Selective’.

A chemical that is used in these herbicides is often referred to as an active ingredient. The majority of selective herbicides contain at least two active ingredients. The reason for this is to give the weed killer product a broader spectrum of weed control (controls a wide range of turf weeds) and increase the effectiveness of control.

The most common active ingredients used into today’s herbicides include:

2,4-D
Mecoprop-P
Clopyralid
Dicamba
Fluroxypyr
MCPA
Florasulam

Although there are others these are the most common ingredients used. Certain ingredients are more effective at controlling different weeds. For instance mecoprop-p is great for clover & trefoil, 2,4-D is ideal for plantains & creeping buttercup. Fluroxypyr has been shown to have some effect against speedwell, one of the most difficult turf weeds to control effectively.

Before reaching for the weed killer, it is important to identify the weeds that need controlling correctly. After all applying the incorrect product can be a waste of both time and money. We have taken much of the guess work out of weed identification with our hand weed id chart.
