Lontrel Advanced Herbicide

Lontrel Advanced Herbicide is a 600 g/L clopyralid herbicide for broadleaf weed control in winter cereals, canola, pastures, fallow land, forests and industrial sites.

It controls thistles, capeweed, skeleton weed and volunteer legumes, and it works well in tank mixes with MCPA and 2,4-D. Growers apply it to actively growing weeds, and higher rates give residual control for several months. As a Group 4 (previously Group I) herbicide, it fits resistance management plans.

Cereals and canola are registered crops, but grain legumes, clover and lucerne are susceptible, so plan rotations carefully. Similar clopyralid products include Sabakem Clopyralid 300SL and Lontrel 750 SG.

Pack Sizes: 1 L, 5 L, 10 L, 20 L. Registrant: Corteva Agriscience Australia Pty Ltd (APVMA #: 65587/110938)

Lontrel Advanced Herbicide LONTREL-ADVANCED Corteva

Description

Lontrel Advanced Herbicide controls broadleaf weeds in wheat, barley, oats, triticale, canola, pastures, fallow land, forests and industrial sites. Specifically, each litre contains 600 g of clopyralid as the dimethylammonium salt. Corteva Agriscience Australia Pty Ltd has registered this soluble concentrate for thistles, capeweed, skeleton weed and volunteer legumes.

Lontrel Advanced is a Group 4 (previously Group I) herbicide that disrupts plant cell growth. Because the label covers cereals and canola, growers can treat weeds within the crop. In addition, higher rates give residual control of certain weeds for several months.

Product highlights

  • Active constituent: 600 g/L clopyralid as the dimethylammonium salt
  • Mode of action: Group 4 (previously Group I)
  • Rate range: 25 mL/ha for cereal thistle tank mixes, up to 4.25 L/ha for plantation silver wattle
  • Grazing withholding: 7 days for crops, pastures and fallow, and 14 days for Pinus radiata plantations
  • Pack sizes: 1 L, 5 L, 10 L and 20 L

How Lontrel Advanced herbicide controls broadleaf weeds

Lontrel Advanced works best on actively growing weeds. Therefore, match the rate to weed size. Small weeds need low rates, whereas large or multi-crown weeds need higher rates.

Situation Key weeds Rate guide
Winter cereals Capeweed, soldier thistle, volunteer legumes 40 to 300 mL/ha
Canola Capeweed, cotula, saffron thistle, skeleton weed 50 to 300 mL/ha
Pastures and fallow Hardhead, Californian and other thistles 25 mL/ha to 2 L/ha

Application, tank mixing and resistance management

Apply with a coarse or larger droplet size, and do not spray if rain is likely within 3 hours. Lontrel Advanced mixes with MCPA, 2,4-D amine, glyphosate and metsulfuron, among others. Resistant weeds can build up under repeated use, so rotate herbicide groups.

Frequently asked questions

Q. How long is the withholding period?

A. Do not graze or cut for stock food for 7 days after application. Pinus radiata plantations need 14 days. In cereals, do not apply later than 10 weeks before harvest.

Q. Can I sow legumes after Lontrel Advanced?

A. Not straight away, because grain legumes are very sensitive to clopyralid residues. Plantback periods run from 9 to 24 months in southern regions, depending on rate. Cereals and canola can follow at any time.

Q. What spray conditions does the label require?

A. Use a coarse or larger droplet size. Spray only in winds between 3 and 20 km/h, and never during a surface inversion. Record each application within 24 hours and keep the record for 2 years.

Q. Does Lontrel Advanced harm clover and medics?

A. Yes, at the higher pasture rates. It eliminates clovers and medics for at least one year, for example, at the hardhead and Californian thistle rates. Do not use it on lucerne.

Q. Which weeds does Lontrel Advanced control in cereals?

A. It controls capeweed, thistles, skeleton weed and prickly lettuce. It also controls volunteer chickpeas, faba beans, field peas, lentils, lupins and medics. Tank mixes add control of weeds such as sowthistle.

Q. Is Lontrel Advanced comparable to Sabakem Clopyralid 300SL, Clopyralid 300 or Lontrel 750 SG?

A. Similar, but not identical. All contain clopyralid. However, concentrations differ. Lontrel Advanced contains 600 g/L, and the 300 products contain 300 g/L. Lontrel 750 SG is a 750 g/kg granule. Therefore, rates differ, so never swap by volume. Always compare both labels before you substitute.

    Cape weed in wheat

    Brian Purdon

    Works very well with a little surfactant. Big Cape problem in wheat paddock. Cape weed can grow quick in warm weather. Gets to big for other chemicals to kill. Been us in my lonterel for 20 years.

    Lontrel = Napalm

    Rom

    I have used this product on California and Scottish Thistle infestations using hand sprayer application. Dye and surfactant helps target and increases effectiveness. Wear protective gear as directed.

    Results are spectacular. 24 hrs after spraying even well established large thistles exhibit obvious and significant damage, making mopping up of missed weeds a simple task. 48 hrs after spraying weeds are completely terminal and underlying native foliage is unaffected. Looks as though napalm has detonated inside the plant. Brilliant results

Rates are label ranges only. Read the full crop, weed and rate tables on the label before you mix.

Re-treatment interval

  • Do not apply more than one application per crop.

Critical comments

  1. It is essential to select a rate appropriate to weed size. Best results come when weeds are actively growing.
  2. The pre-sowing rate of 75 mL/ha should only be used in a tank mix with Spray.Seed or glyphosate.
  3. Rates of 150 to 300 mL/ha before crop emergence give good suppression (150 to 250 mL/ha in canola). Use 300 mL/ha for good control of capeweed and sub clover.
  4. Apply pre-emergence treatments to moist soil, close to the time of major weed germination.
  5. Faba beans and lupins will only be suppressed.
  6. Do not use on lucerne in pastures. Clovers and medics will be eliminated for at least one year.
  7. Do not spray flowering thistles. Treat thistles from the rosette stage, before stem elongation.
  8. Where thistles are over 20 cm across, use Lontrel Advanced plus MCPA instead of the nodding thistle rate.
  9. Add a wetter such as BS1000 at 0.2% v/v for Californian thistle in pastures. Regrowth usually needs retreatment the following year.
  10. Lontrel Advanced can damage Acacia species. Consult the registrant before using it in forests where Acacia is a significant component.
  11. In Clearfield canola, do not exceed 75 mL/ha, as reduced control of grass weeds may occur.

Rates are a general guide only. Before opening, carefully read Lontrel Advanced Herbicide directions for use, precautionary and protection statements, storage and disposal, safety directions and first aid instructions. The product is designed for the particular purpose indicated on the label. Failure to use the product strictly as directed may be illegal and dangerous, and may render the product ineffective.

Questions and answers from customers

    Is Lontrel Advanced Herbicide safe to use on dichondra lawns?

  1. Q Is Lontrel Advanced Herbicide safe to use on dichondra lawns?
    Asked by Gundi on May 12, 2026 2:32 pm
    Answered by the admin

    Lontrel Advanced is not registered for use in lawns or turf situations. Its APVMA-registered label covers broadleaf weed control in winter cereals, canola, pastures, fallow land, forests, and industrial/commercial situations only — there is no lawn registration. Dichondra (Dichondra repens) is also a broadleaf plant, meaning it would be susceptible to damage from clopyralid-based products. For broadleaf weed control suitable for dichondra lawns, we recommend browsing our turf and domestic herbicide range or contacting us at [email protected] for a product recommendation.

  2. What is the waiting period before I am able to plant Australian native tube stocks after using Lontrel Advanced Herbicide? Can I add Simazine (pre-emergent), Verdict (grass selective) and Uptake Oil together so that I can target grasses as well as put a pre-emergent in place for any weeds that may come up in the coming months over winter (June - August)?

    Unfortunately, the label for Lontrel Advanced Herbicide does not list the plantback period for native species. The manufacturer (Corteva) may have data on this particular situation and can be contacted on 1800 700 096 for clarification. Verdict 520, Lontrel, Uptake Oil and Simazine are all listed as compatible products in tank mixes.

    Lontrel Herbicide is available as a liquid concentrate (Lontrel Advanced Herbicide) and a soluble granule (Lontrel 750 SG Herbicide). Both products contain the active ingredient Clopyralid and must be diluted with water before applying as a spray. Whether to use a liquid concentrate or SG formulation depends on the end user. The granules are popular as they are easy to handle and do not have plastic containers to dispose of.
