Product Description

METSULFURON METHYL is a herbicide containing 600 g/kg metsulfuron-methyl, in a 500 g pack. Metsulfuron 600 WG labels list non-crop areas (rights of way, commercial and industrial areas), pastures, winter cereals and brush weed control, for weeds such as blackberry, bracken, gorse, lantana and Paterson curse, with rates from 1 g to 20 g depending on the weed and the method (hand gun, boom, gas gun or aerial). Domestic and public service areas are listed alongside pastures, forests and rights of way for certain weeds. Lawns are not listed. Check the label on your pack before use.

It can damage plants you want to keep. The label says to minimise contact with desirable plants, and not to apply, drain or flush equipment on or near desirable trees or other plants, on areas where their roots may extend, or where the chemical may be washed or moved into contact with their roots. Many crop species are sensitive to metsulfuron methyl, legumes will be damaged or removed, and introduced grasses may be severely damaged. The product stays in the soil for a time that depends on soil pH, moisture, temperature and organic matter, and recropping intervals apply before sensitive crops or pasture species are planted.

Restraints and safety. Do not spray if rain is expected within 4 hours, do not treat weeds that are under stress or not actively growing, and do not store the prepared spray for more than 2 days. Do not contaminate streams, rivers or watercourses, do not apply to weeds growing in or over water, and do not spray across open bodies of water. When opening the container and preparing the spray wear elbow-length PVC gloves and goggles; if applying by hand also wear cotton overalls buttoned to the neck and wrist and a washable hat.

Tips for use

Application Tips:

Avoid spraying if rain is expected within 4 hours.
Only prepare spray you can use within 2 days; do not store longer.
Do not mix this product with others in the tank for storage.
Avoid applying on pastures with paspalum notatum or setaria spp., as growth will be reduced.
Newly sown pastures may be damaged—do not apply.
Not suitable for pasture seed crops.

 

Using a Surfactant/Wetting Agent:

Always use a surfactant or penetrant with this herbicide.
Metsulfuron alone: Use a non-ionic surfactant (100 mL per 100 L of spray).
With Glyphosate: Use a non-ionic surfactant or an organosilicone penetrant (e.g., Pulse, Probe). Check mixing instructions carefully.
Gas Gun Applications: Add an organosilicone penetrant (10 mL per 5 L or 200 mL per 100 L of spray).
With Mineral Oil: Add 1 L of oil per 100 L of spray but still use a non-ionic surfactant.
Follow the companion product label when tank mixing.

 

Product Compatibility:

Compatible with glyphosate and common herbicides like MCPA, 2,4-D, Dicamba, Clopyralid, Fluroxypyr, and insecticides like chlorpyrifos.
Always check the label of the other products for restrictions.

 

Environmental Effects:

Low toxicity to birds, bees, fish, and earthworms.
Breaks down faster in acidic, moist, and warm soils but may move more in alkaline soils.
Absorbed quickly by plants, breaking down into non-herbicidal compounds.

 

Safety Directions:

Harmful if swallowed. Avoid contact with eyes and skin.
When handling the product: Wear PVC gloves and goggles.
When spraying by hand: Wear cotton overalls, a washable hat, and gloves.
If it contacts skin, wash immediately with soap and water.
If it gets in eyes, rinse thoroughly with water.
Wash hands and all protective gear after use.

 

Livestock Protection:

No withholding period; stock can graze immediately.
For best results, remove stock for 3 days after application.
Avoid grazing on treated toxic plants (like bracken) until they are fully browned.

 

First Aid:

If poisoning occurs, contact a doctor or Poisons Information Centre (Australia: 131 126).

Frequently asked questions

Do I need a licence to buy or use these?

Most products here are unrestricted and can be bought and used by anyone following the label. A few are restricted chemical products that need a chemical user permit in some states - those are flagged on the product page. If in doubt, check the poison schedule on the label.

How do I work out the mixing rate?

The label gives a rate either per 100 L of water (a concentration) or per hectare or per 100 square metres (an area rate). For a knapsack, work out the area one tank will cover, then scale the per-area rate to that tank volume. Calibrate the sprayer before you start.

Why do the same chemicals come under different brand names?

Once an active ingredient comes off patent, several companies register their own version. A generic glyphosate 360 and a big-brand glyphosate 360 are the same active at the same strength - the difference is formulation quality, surfactant load and price.
