Ronstar Turf and Ornamental Herbicide
Active Ingredient: Oxadiazon @ 20g/kg
Ronstar Turf and Ornamental Herbicide is a selective, pre-emergent herbicide for the control of certain weeds in Turf or Woody Ornamental Shrubs and Trees in nurseries. Ronstar is a herbicide that offers great weed control without root pruning.  Ronstar is a pre-emergent herbicide providing control of germinating weed seedlings for up to 10weeks after application.
Why choose Ronstar Turf And Ornamental Herbicide.
- Is not taken up by roots – does not affect root systems (no root-pruning) and is not translocated through the plant.
- High level of selectivity – allowing use in a wide range of ornamental species.
- Kills weeds prior to emergence from soil.
- Controls germinating weeds for up to 10 weeks giving season-long weed control.
- Does not degrade after exposure to long periods of sunlight, therefore weed control is maintained for a long period.
- Oxadiazon becomes strongly bound to soil humic and clay particles and therefore does not leach from the soil under heavy irrigation or rainfall. Oxadiazon is also the active ingredient used in Oxafert Herbicide And Fertiliser.
- Retains activity over a range of soil types, organic matter and pH.
- Degraded in soil via microbial pathways – research shows no evidence of a build-up of oxadiazon in the soil after several annual applications.
