Indigo Prosedge 750 DF Halosulfuron Methyl
%20and%20Nutgrass%20in...){kind=link}
Group 2 Herbicide
ProSedge 750DF is a systemic herbicide containing the active ingredient Halosulfuron-methyl. It is registered for the control of Mullumbimby Couch (Green Kyllinga) and Nutgrass in a broad range of turfgrasses including Common Couch, Hybrid Couch, Bentgrass, Buffalograss, Kikuyu, Queensland Blue Couch, Perennial Ryegrass, Tall Fescue, Durban Grass and Carpetgrass. ProSedge 750DF is a 750g/kg Dry Flowable Dispersible Granule formulation.
Key Features:
- Strong activity on sedges.
- Possesses systemic activity that moves through the plant and removes the sedge’s underground growing parts.
- Broad spectrum of turf safety. Registered for use on 10 turfgrass varieties, both warm and cool season.
- Low active ingredient output.
- No odour. Easy to use in urban environments.
- Highly dispersible, dry flowable formulation.
- Available in an easy to pour 500g bottle, with a measure providing increments of 10g up to 100g.
- Left intact in the original package, ProSedge 750DF kept in a cool, dry place can be stored for many years without affecting its performance.
Maximising Performance:
Spray Tank Water Quality
- ProSedge 750DF is impacted by water hardness in spray tanks. Water hardness is a measure of the total concentration of positively charged minerals (cations) in water.
- Calcium (Ca2+), Magnesium (Mg2+), and Iron (Fe2+, 3+) are all cations which in sufficient quantities can make water hard and impact upon halosulfuron methyl stability and longevity in the spray tank.
- To avoid hard water conditions, it is recommended to apply Ammonium Sulphate at a rate of 3kg/100m2.
Surfactant Addition
- ProSedge 750DF must be applied with a non-ionic surfactant to ensure uptake.
- The label indicates to use a 1000 g/L non-ionic surfactant at 120mL per 100L.
- For handgun or knapsack application, the label indicates to add surfactant at 12mL/10L of water.
- For 859g/L adjuvants (Octane), this equates to 140mL per 100L of water.
- For handgun and Knapsack applications, Octane Extender, Sticker and Spreader should be used at 14mL/10L of water.
Tank Mix Compatibility
- ProSedge 750 DF is compatible with glyphosate, dicamba/MCPA, bromoxynil/MCPA mixtures and amine formulations of 2,4-D. Organophosphate insecticides should not be tank mixed or applied 7 days prior or 3 days after application of ProSedge 750 DF, as turf injury may result.
