Centaur is a post-emergence herbicide with rimsulfuron and thifensulfuron-methyl in water-dispersible granules for maize against annual and some perennial grass and broadleaf weeds.
Main advantages
- Taken up by the leaves — treatment of emerged weeds
- Maize at the 2–5 leaf stage — one treatment
- Macho surfactant 0.2–0.3 l/ha — in the same tank
- Not below +10 °C — temperature limit for treatment
- Pack size 0.5 kg — for 20–25 ha
Overview
About this product
Centaur is a mixture of two sulfonylureas: rimsulfuron 500 g/kg and thifensulfuron-methyl 250 g/kg. The substances are taken up mainly by the leaves of weeds, move to the root tips and stop cell division.
Emerged weeds are treated at the early stages of their development. Maize is sprayed once at the 2–5 leaf stage at 20–25 g/ha with Macho surfactant 0.2–0.3 l/ha, with a working solution of 200–300 l/ha.
The manufacturer does not recommend treatment at temperatures below +10 °C. Pack size 0.5 kg.

| Mode of action | Rimsulfuron and thifensulfuron-methyl are sulfonylureas (HRAC group 2). They are taken up mainly by the leaves of weeds, move to the root tips and inhibit acetolactate synthase, an enzyme of branched-chain amino acid synthesis, so cell division stops in susceptible weeds. |
