Surefire Metsulfuron 600WG Herbicide

If you are applying Surefire Metsulfuron 600WG Herbicide in a pasture situation as per the label directions, the recommended knapsack rate for Onion Weed is 1 gram of product per 10 litres of water. It is essential to also add a non-ionic surfactant to the mix to ensure the herbicide effectively sticks to the waxy leaves of the weed. It is important to note that Surefire Metsulfuron 600WG is registered to control Onion Weed in pasture and non-crop situations only and is not recommended for use in a residential lawn, as it can damage many common turf species. Regarding your question about tank mixing, Weedforce BroadSweep Herbicide contains the active ingredients MCPA and Dicamba. While mixing Metsulfuron with these types of herbicides is a common practice, this specific combination is not confirmed as being compatible on the product labels. To ensure the products mix correctly, we recommend you first perform a 'jar test' to check for compatibility before mixing a full batch. For the most definitive advice, you could also contact the product manufacturers directly.

When using Surefire Metsulfuron 600WG herbicide, including a surfactant or wetting agent is important to ensure optimal herbicide performance. The recommended type and application rate may vary slightly depending on the situation. Surefire Metsulfuron 600WG herbicide recommends using either a non-ionic surfactant (e.g. PCT Reactor 600, Conquest Wetter 1000 Surfactant, or Alphakem Wetter 1000) or an organosilicone penetrant (e.g. PCT Reactor Penetrant, Eurochem Penetrant, or Consume Penetrant), depending on your situation, per the directions of use table. Where no specific surfactant or wetting agent is recommended in the directions of use table, you should use a non-ionic surfactant.

The directions of use table can be found on the product label under 'SDS and Technical' on the product page on our website.

Metsulfuron 600WG Herbicide is not registered or recommended for turf or domestic situations. We would suggest a selective herbicide, such as Fairway Turf Herbicide, which lists creeping spurge/caustic weed (Euphorbia drummondii) as a controlled species in established turf varieties, including Common Couch, Queensland Blue Couch, Kikuyu, Paspalum, Fescue, Bentgrass, and Ryegrass. You can find it by searching 'Fairway Turf Herbicide' in the search bar at the top of the Specialist Sales website. Please ensure you read the SDS and Label before purchase and use to confirm suitability for your situation. 

Surefire Metsulfuron 600WG Herbicide is not registered or recommended for removing Agapanthus. To the best of our knowledge, no herbicides are registered for this use. However, off-label applications with Vigilant II Herbicide Gel can be trialled at your own risk.

Metsulfuron 600WG Herbicide is not registered or recommended to control Biddy Bush (Sifton Bush). Herbicides such as Grazon Extra, Hatchet, Scrubba, Woody Extra and Trodon 75D are more suitable. Metsulfuron 600WG Herbicide is registered to be effective on St. John's Wort when mixed with Glyphosate. Herbicides like Grazon Extra, equivalents to Grazon DS (Hatchet & Scrubba), Starane and Ester are more suitable for St. John's Wort control.

Surefire Metsulfuron Methyl 600 WG Herbicide is a selective herbicide used to control certain broadleaf weeds in winter cereal crops and broadleaf weeds and brush species (woody weeds) in pastures, rights of way, commercial and industrial areas. Metsulfuron 600WG Herbicide kills many broadleaf plants but is not registered to control Angel's tears (Soleirolia soleirolii) and is not registered or recommended for use in any domestic turf or garden situation, and to do so is at your own risk. N.B. buffalo lawn is a broadleaf species and may suffer severe damage or death if Metsulfuron is applied. 

Metsulfuron 600WG Herbicide can kill or severely damage shrubs and trees, including gums (also broadleaf species). Metsulfuron will be leached into the soil after rainfall and remain in the ground for a time. If a tree's root system comes in contact with the Metsulfuron, it can be translocated throughout the tree. Depending on the application rate and the size of the tree, the result may be the tree's death or severe damage. To our knowledge, no selective herbicides are registered or recommended to control Angel's tears.

The best practice advice when using Surefire Metsulfuron 600WG Herbicide is to avoid application close to desirable species. Although Surefire Metsulfuron 600WG Herbicide does not claim control over any palm species, severe death or damage could occur.

Surefire Metsulfuron 600WG Herbicide is a water-dispersable granule (WDG). Hence the granules are formulated to be dissolved in water at the recommended rates indicated in the 'directions for use' label. They are not broadcast in their granular form. Metsulfuron tank mixes can be applied by 'hand spray', 'boom', or 'gas gun'. Always read the 'directions for use' carefully to ensure suitability to your situation. This can be found on the Surefire Metsulfuron product screen; scroll down to the heading 'SDS & Technical' and select; a PDF file will be available to print or download.

Although Surefire Metsulfuron 600WG Herbicide registered 'directions for use' does not list rainforest tree species, they are classified as broadleaf plants and are likely to be susceptible to the Metsulfuron-Methyl. When applying metsulfuron-methyl, there is a risk of root uptake of non-target species due to its mobility potential, which is affected by environmental factors, soil profiles, temperatures and rainfall. The half-life of metsulfuron-methyl ranges from 14 to 180 days, with a typical time of 30 days. Metsulfuron-Methyl is broken down in the soil mainly by chemical hydrolysis and, to a lesser degree, by soil microbes. Other factors which affect breakdown are soil pH, soil moisture and temperature. Research indicates it is faster in warm, wet, and acidic soils and slowest in alkaline, cold, and dry soils.

Surefire Metsulfuron Methyl 600 WG Herbicide is a selective herbicide used to control certain broadleaf weeds in winter cereal crops and broadleaf weeds and brush species (woody weeds) in pastures, rights of way, commercial and industrial areas.  Metsulfuron Methyl is not registered for the control of grasses. 

Herbicides made from MSMA, such as Militate MSMA Herbicide are registered to target Crab Grass (Digitaria sanguinalis), Summer Grass (Digitaria sanguinalis) & Paspalum (Paspalum dilatatum) in certain turf situations.

Surefire Metsulfuron Methyl 600 WG Herbicide is a selective herbicide used for the control of certain broadleaf weeds in winter cereal crops and broadleaf weeds and brush species (woody weeds) in pastures, rights of way, commercial and industrial areas.  Metsulfuron Methyl is not registered for the control of grasses. You may want to consider a number of other products which are registered for post-emergent control of a variety of grassy weeds in turf as follows:  DSMA Selective Herbicide, Metric Herbicide, Quinstar 200SC Herbicide.

Creeping Indigo is not registered to be controlled by Metsulfuron 600WG Herbicide.  Metsulfuron is also not registered or recommended for use in domestic gardens or turf situations, as damage to close-by non-target species (trees, shrubs etc.) can occur. 

Metsulfuron 600WG Herbicide is not registered or recommended for use in any domestic turf or garden situation, and to do so is at your own risk. Metsulfuron is one of the few herbicides used to successfully remove Singapore daisies in areas of native vegetation and non-crop areas. This is done as per the APVMA Permit # 9907. As Metsulfuron will not list Zoysia (or any turf species) as a safe use situation, conducting a small off-label trial in a secluded area would be necessary.

Surefire Metsulfuron 600WG Herbicide can kill or severely damage trees, including gums. Metsulfuron will be leached into the soil after rainfall and remain in the soil for a time. If a gumtrees root system comes in contact with the Metsulfuron, it can be translocated throughout the tree. Depending on the application rate and the size of the tree, the result may be the tree's death.

Unfortunately, there is no data regarding the plant back period for shrubs & plants to be planted in areas sprayed with Metsulfuron-Methyl Herbicide. As the half-life of metsulfuron-methyl ranges from 14 to 180 days, with a typical time of 30 days, the plant back period could be up to 6 months. Metsulfuron-Methyl is broken down in the soil mainly by chemical hydrolysis and, to a lesser degree, by soil microbes. Other factors which affect breakdown are soil pH, soil moisture and temperature. Research is faster in warm, wet, and acidic soils and slowest in alkaline, cold, and dry soils. 

Surefire Metsulfuron 600WG Herbicide is not registered for or claims to control the weeds you listed.  However, they are classified as broadleaf plants, likely to be susceptible to the Metsulfuron-Methyl.  We suggest mixing a 2nd broadleaf herbicide with the Metsulfuron to spike the mix and give you better results.  A herbicide such as 24D Amine or Grazon Extra would be recommended for this purpose, plus a suitable wetting agent or penetrant.

The directions for Surefire Metsulfuron 600WG Herbicide are available via the Specialist Sales website in the 'SDS and Technical' tab on the product page.  The recommended application rate of Surefire Metsulfuron Metsulfuron when spraying Singapore Daisy is 10g per 100L (1g/10L) water plus wetting agent (permit #11463).

The measuring spoon provided with the Surefire Metsulfuron 600WG Herbicide holds a total of 11grams.  There are no other measuring increments marked on the spoon.

Carrot weed, also known as annual ragweed, ambrosia, American wormwood, carrot weed, hay fever weed, hogweed or common ragweed, is not registered to be controlled by Metsulfuron 600WG Herbicide.  Carrot weed is susceptible to other selective broadleaf herbicides such as Dicamba M and Dicamba 500, so Metsulfuron will likely have some control, but as it is not registered for this purpose, a test or trial should be undertaken first, as with any 'off-label' use.  We do not recommend using Metsulfuron 600WG Herbicide in domestic or turf situations.

The use of Metsulfuron 600WG Herbicide for Singapore Daisy control is registered for use under a permit by the APVMA and hence is not listed on the product labels.  As Metsulfuron 600WG Herbicide is a slow-acting herbicide, we recommend waiting at least 2-3 weeks after application before mowing or cutting the grass.  If you get a quicker kill of the Singapore Daisy and are confident the chemical has translocated into the root system, then mowing can occur sooner.

Metsulfuron Methyl mainly targets broadleaf species of plants and is not registered to have any control over grasses like paspalum.  It is also not registered or recommended for use in domestic gardens or turf situations as damage to close-by non-target species (trees, shrubs etc.) can occur.

To the best of our knowledge, there are no chemicals registered to control Wynn-Cassia.  As Wynn-Cassia is a short-lived herbaceous perennial legume, herbicides registered to control broad-leaved plants are recommended.  We believe a mixture of Metsulfuron-Methyl, Grazon Extra (or equivalents to Grazon DS) and a suitable wetting agent/penetrant would be worth testing to evaluate control.

To the best of our knowledge, there are no chemicals registered in Australia to control Richardia.  Feedback from customers who have done their own 'off-label' trials with selective broadleaf herbicides has reported good results.  These chemicals included Stadium Turf Selective Herbicide and Dicamba M Selective Herbicide.  As Metsulfuron 600WG Herbicide is a selective herbicide, it may also be effective on Richardia.  If you are going to do your own trial with Metsulfuron, caution is recommended as Metsulfuron can cause damage or death to non-target broadleaf species such as shrubs, trees, roses, etc.

Metsulfuron 600WG Herbicide does not claim any control over snakeweed or billygoat weed.  These plants may be susceptible to the Metsulfuron-Methyl, but you will have to try the product off-label to test the results.  We suggest you look at 24D Amine 625 Herbicide, which includes these weeds on its label.

Metsulfuron Methyl Herbicide is registered to target specific broadleaf species without harming grasses.  Metsulfuron Methyl is unlikely to have any effect on controlling green couch grass.
