Syngenta Gramoxone 360 Pro 20L: High-Load Paraquat Knockdown Herbicide
Syngenta Gramoxone 360 Pro is the highest-load paraquat product available in Australia, containing 360g/L paraquat (present as paraquat dichloride). It is a fast-acting, non-selective knockdown herbicide used in broadacre and horticultural situations for rapid control of a wide range of grass and broadleaf weeds. As a contact herbicide, it works on green plant tissue it touches, delivering quick brownout, and it is rainfast very soon after application, so results are reliable even when the weather is against you.
The high-load formulation is the point of difference. Because it carries more active per litre, there is around 30 per cent less product to transport, handle and store compared with older paraquat formulations, which is a real efficiency for larger operations moving and storing chemical in volume. Syngenta states it delivers equal and often better efficacy than existing paraquat formulations, with the added flexibility to tailor adjuvants to maximise performance for the target weeds and situation.
This is a professional broadacre and horticultural product supplied in large commercial volumes, including 20L, 100L and 1,000L. It is a restricted chemical intended for licensed and accredited users, and must be used strictly in accordance with its APVMA-registered label.

How to Use
Gramoxone 360 Pro must be applied strictly according to its APVMA-registered label. The correct rate, water volume, adjuvant and situation vary by weed and use pattern, so always follow the label for your specific situation rather than a general rate. As a contact knockdown, thorough, even coverage of the target weeds is essential for good results. Add any recommended adjuvant as directed, keep the tank agitated, and apply to actively growing weeds. Observe all withholding periods, re-entry periods and application conditions on the label.
