Metsulfuron Methyl

Metsulfuron Methyl is a residual pre and post emergent weed killer which targets broadleaf weeds, onion weed (guildford grass) and creeping oxalis. It is labelled to control broadleaf weeds and some annual grasses in pastures and industrial areas. It is very effective on weeds that include bulbs and tubers. It is recommended to only spot spray weeds as it can kill different types of plants as well as the targeted weeds.

Metsulfuron Methyl is extremely effective weed killer, especially on weeds with a small surface area such as creeping oxalis and guildford grass. It is also very effective against broadleaf weeds, so while it is more expensive initially then other broadleaf weed killer, it will do more weeds and go a lot further.

Other products which have the same active ingredient that we have stocked include Brush Off, Ken-Met and Associate. SureFire Metsulfuron is the best value for money.

Remember, weeds become a problem in eroded areas. This usually happens when areas do not get enough water through summer or there is to much shade. The less bare areas, the harder it is for weeds to compete.

Metsulfuron Methyl has

  • Low application rates per hectare
  • Environmentally safe to use
  • Very high efficacy
  • Grass-friendly

Metsulfuron Methyl  is a very safe, low toxicity and highly effective weed killer. It has a low toxicity to birds, aquatic organisms, bees and earthworms. It also has a low toxicity to mammals and not classified as a poison in the Standard for the Uniform Scheduling of Drugs and Poisons.

When to Use: Completely eradicating the weed before it seeds and improving the general health. All weeds are easier to kill when they are healthy with more surface area to suck up the chemical, so try not to slash the area before spraying. Try and spray when the weed is more juvenile. This way you spray before it seeds and before the stem gets more mature and woody, allowing the chemical to be absorbed better into the plant. Spray when as dry as possible and allow to stay on the plant for a couple of days before watering.


Product Type: Herbicide
Mode of Action: Group B Herbicide

Group B herbicides block the ALS enzyme essential in the production of the
branched-chain fatty acids (amino acids) leucine, isoleucine and valine. These amino
acids are essential for the production of proteins and for normal plant growth, while
also providing precursors for a number of secondary products such as cyanogenic
glycosides, glucosinolates and acyl-sugars.

Group B herbicides are weak acid herbicides with moderate water solubility and are absorbed via the leaves and the roots, using the aqueous pathway.
