SureFire Metsulfuron Methyl Herbicide 500g: Selective Herbicide for Brush, Woody and Broadleaf Weeds

SureFire Metsulfuron Methyl: A Selective Herbicide for Brush and Broadleaf Weeds

SureFire Metsulfuron Methyl is a highly potent, selective sulfonylurea herbicide containing 600g/kg metsulfuron methyl as a water dispersible granule. It's registered for the control of brush and broadleaf weeds in native pastures, rights of way, commercial and industrial areas, and certain broadleaf weeds in winter cereal crops, as set out in the label's Directions for Use. It's a Group 2 herbicide (previously Group B), made by PCT Holdings in Queensland. This 500g pack suits landholders, contractors and farmers treating woody and broadleaf weeds across large areas.

How Does Metsulfuron Methyl Work?

Metsulfuron is a systemic herbicide with both foliar and soil activity. It's absorbed through the leaves and roots, then moves to the growing points, where it blocks the ALS enzyme that plants need to make amino acids. Cell division in the shoots and roots stops, so weeds stop growing within a day or so. Visible yellowing takes 1 to 3 weeks or longer, and complete brown-out of woody weeds can take 3 to 6 months. Because it works at very low rates, a small amount treats a large area.

What Weeds Does Metsulfuron Kill?

Metsulfuron controls more than 40 brush, broadleaf and bulbous weeds listed on the label. It's particularly effective on weeds with bulbs or tubers. Common targets include:

• Woody and brush weeds: blackberry, lantana, gorse, bracken and tree-of-heaven
• Broadleaf weeds: Paterson's curse, thistles, sorrel and erodium
• Bulbous weeds: onion grass (Guildford grass), doublegee and cape tulip

Always check the label for the weeds listed for your situation and state.

Where It's Used

• Native pastures: removes broadleaf and brush weeds while leaving most native pasture grasses.
• Rights of way: roadsides, rail lines, fence lines and easements.
• Commercial and industrial areas: depots, yards and non-crop sites.
• Winter cereal crops: wheat, barley, oats and triticale, for certain broadleaf weeds as per the label.

Not for Home Lawns

SureFire Metsulfuron Methyl isn't registered for use on domestic lawns. It can severely damage or kill common lawn grasses such as buffalo, kikuyu, ryegrass and blue couch. Clover and other legumes in pastures are also removed. For broadleaf weeds in a home lawn, use a selective lawn weed killer made for your grass type.

Soil Residue and Plant-Back Intervals

Metsulfuron stays active in the soil for a period after spraying, which helps control new weed seedlings but also affects what you can plant next. Sensitive crops can need long plant-back intervals, in some cases up to 22 months. Don't spray over the root zone of trees, shrubs or garden plants you want to keep, as roots can take up the herbicide from the soil. Follow the label's re-cropping intervals before sowing.

How to Use SureFire Metsulfuron

• Read the attached label booklet for your weed, situation and application method.
• Half-fill the spray tank with clean water, add the measured granules and agitate until fully dispersed, then top up.
• Always add a non-ionic wetting agent or penetrant, as directed on the label, so spray spreads and sticks to waxy leaves.
• Spray to thoroughly wet the foliage of actively growing weeds. Don't spray weeds stressed by drought, waterlogging or frost.
• Avoid drift onto desirable plants, crops, gardens and waterways.
• Clean spray equipment thoroughly after use, as small residues can damage other plants later.

Safety

Harmful if swallowed and will irritate the eyes and skin. Wear gloves, eye protection and protective clothing when handling the granules and spray. Don't contaminate dams, waterways or drains. Store in the closed original container in a cool, well-ventilated place away from children, animals and food. If poisoning occurs, call the Poisons Information Centre on 13 11 26.

Frequently Asked Questions

What is SureFire Metsulfuron Methyl used for?

It controls brush and broadleaf weeds in native pastures, rights of way, commercial and industrial areas, and certain broadleaf weeds in winter cereal crops, as per the label.

Can I use SureFire Metsulfuron on my lawn?

No. It's not registered for domestic lawns and can severely damage buffalo, kikuyu, ryegrass and blue couch. Use a selective lawn weed killer made for your grass type.

What weeds does metsulfuron kill?

Over 40 brush, broadleaf and bulbous weeds, including blackberry, lantana, gorse, bracken, tree-of-heaven, Paterson's curse, thistles, sorrel, onion grass and doublegee. Check the label for your situation.

How does metsulfuron methyl work?

It's absorbed through leaves and roots and blocks the ALS enzyme, which stops cell division in the shoots and roots. Growth stops quickly, but visible symptoms take weeks and woody weeds can take months to die.

How long does metsulfuron take to work?

Weeds stop growing within about a day. Yellowing usually shows in 1 to 3 weeks or longer, and full brown-out of woody weeds can take 3 to 6 months.

Does metsulfuron need a wetting agent?

Yes. Add a non-ionic wetting agent or penetrant as the label directs, so the spray spreads over and penetrates the leaf surface.

What is the best herbicide for broadleaf weeds?

It depends on where the weeds are. For brush and broadleaf weeds in pastures, rights of way and industrial areas, metsulfuron is a widely used, low-rate option. For broadleaf weeds in home lawns, use a lawn-safe selective herbicide instead.
