Description

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.

Directions Of Use

General Application Rate:

150 or 200kg per Hectare (1.5kg – 2kg per 100m²) (15gm – 20gm per 1m²)

Application:

Apply using a properly calibrated granular applicator which will apply the granules in a uniform pattern.
Uniform application is essential for satisfactory weed control.
Calibrate the applicator prior to use according to the manufacturer’s instructions, and check the applicator frequently to ensure that the equipment is working properly.
After application, ensure granules are washed or brushed off the foliage, particularly the foliage of prostrate and dense ground-cover plants.
Do not apply granules when foliage is wet.

Turf: As above.

Ensure that the turf area is free of leaves and other debris, mowing if necessary so that the granules reach the soil surface.
Measure the area to be treated and apply the required amount using a properly calibrated granular applicator as above.
The oscillating spout and rotary type fertilizer spreaders are recommended for large areas.
The activity of this product is dependent on moist soil conditions.
If rain is not received within 2 days after application, apply through sprinkler irrigation to wash granules off the leaves and help distribute the granules on the soil surface.
Do not apply granules when the turf foliage is wet.
If the soil is to be top-dressed with fertilizer, do not apply this product until the top-dressing operation is completed.
Apply prior to germination of the weeds (usually from late winter to early Spring, late August to early September). Summer grass (Digitaria ciliaris) will be suppressed at this rate.

Rates are a general guide only. Before opening, carefully read Ronstar Turf And Ornamental Herbicide directions for use, precautionary and protection statements, storage and disposal, safety directions and first aid instructions.

'Ronstar Turf and Ornamental Herbicide' is registered for use in field-grown ornamental crops to control creeping oxalis. Ronstar Turf and Ornamental has been used on a wide range of ornamental plant species without damage. However, some species and varieties are particularly sensitive to chemical products. As this sensitivity could be related to local conditions, it is advisable to treat only a small number of plants first in order to determine their reaction to the product before treating a whole crop. You could also consider Freehand Herbicide for this application.

Ronstar Turf and Ornamental Herbicide does not explicitly list any precautions or restraints for use around succulent plants or cacti, so the risk of damage or death is unknown. The active ingredient in Ronstar is not taken up by existing plant roots and does not affect root systems. We would suggest contacting the manufacturer, Bayer Environmental Science, on Ph: 1800 804 479 as they may have trial data on different species not included on the product label.
