Herbicides are used to control weeds in many situations including the quest for growing a food or fibre crop, managing turf or an ornamental garden, controlling woody weeds or simply to maintain a weed free amenity area.
Non-selective herbicides are usually used to manage existing weeds and are designed to kill any plants to which they are directly applied (Knockdown herbicides). Examples include products containing glyphosate, paraquat and glufosinate. Non-selective herbicides may also be used in some cases to prevent establishment of weeds by preventing germination through a residual action in the soil.
Selective herbicides target certain plant species only and may be used just prior to (Pre-emergence), or during a crop growing season (Post-emergence) to target those weeds that are likely to compete with the crop for nutrients and reduce its yield potential.
Before using a herbicide to manage weeds, be sure to seek advice from your local CRT store and always read the label carefully to ensure that you choose the most suitable and cost effective option for your situation, including information regarding crop or desirable plant safety, any plant-back waiting period restrictions, stock grazing withholding periods and best practice in terms of managing herbicide resistance.
At CRT, we know herbicides, and we are here to help, so call into your local store and ask them for a weed management solution that is right for you.
