Description
AC Sporo 745 Flupropanate Herbicide for Pasture Grass Control
AC Sporo 745 Herbicide delivers targeted, residual control of some of Australia’s most damaging pasture grasses, including serrated tussock, Parramatta grass, African love grass, rats tail grass, kikuyu, couch, and Johnson grass. Formulated by Axichem Pty Ltd, it contains 745 g/L flupropanate present as the sodium salt, and carries APVMA Approval No. 64857/143888. It suits pasture situations, non-crop areas, and industrial use sites where persistent grass infestations need long-term management.
This product works as a Group 0 herbicide, belonging to the chlorocarbonic acids group with an unknown mode of action. As a result, it provides a useful rotational option for resistance management where other herbicide groups have been used repeatedly. Notably, AC Sporo 745 Herbicide acts slowly. Control of existing growth typically takes 3 to 12 months, depending on weather conditions and plant senescence. Furthermore, the product delivers residual soil activity, suppressing grass seed germination over an extended period following application.
Key Application Summary
| Crop/Situation | Weeds Controlled | Rate (Ground/ha) |
|---|---|---|
| Pastures and non-crop | Serrated Tussock | 2L/ha |
| Pastures and non-crop | Parramatta grass, African love grass | 2-3L/ha |
| Pastures and non-crop (Qld) | Rat’s Tail Grass | 2L/ha |
| Non-crop (Qld, NSW, ACT) | Paspalum, Kikuyu, Couch | 9L/ha |
| Non-crop | Johnson Grass, Columbus Grass | 12-22L/ha |
The optimal application window is November to February inclusive. This timing reduces impact on desirable pasture species and allows residues to leach before autumn re-seeding. Apply in 800 to 2,000 litres of water per hectare for ground boom equipment, and ensure full leaf coverage.
Frequently Asked Questions
How long does AC Sporo 745 Herbicide take to work?Â
Control of existing growth takes 3 to 12 months. Results depend on weather conditions, plant senescence, soil type, and rainfall. This is a slow-acting, residual product, not a knockdown herbicide.
Can AC Sporo 745 be mixed with other herbicides?
Yes. The product is compatible with glyphosate to improve the knockdown of existing vegetation. When mixing with dispersible powders, first make a slurry, add to a half-filled tank, then add flupropanate and fill to volume.
Is a wetting agent needed with AC Sporo 745?
Yes. The addition of 100mL of a non-ionic surfactant (600 g/L) per 100 litres of spray is recommended for best results.
What are the stock grazing restrictions after application?
Two withholding periods apply. After spot spraying, do not graze or cut for stock feed for at least 14 days. After blanket treatment, do not graze or cut for 4 months. Additionally, stock must not graze treated areas for at least 14 days before slaughter, regardless of treatment method.
Can AC Sporo 745 be used near waterways or in channels?
No. Avoid use in channels, drains, and areas where roots of desirable plants may extend. Do not contaminate streams, rivers, or watercourses.
