Improving glyphosate and herbicide performance often comes down to one simple factor: using the right spray adjuvant in the tank mix. For years, growers have relied on combinations like LI700 (0.25%) plus Ammonium Sulphate (AMS at 800 g/100 L) to get the best out of their knockdowns or summer sprays. But now there’s a new option on the block- Outright 770 – and it brings all the benefits of oils, wetters, and AMS together in one drum.
Meet VicChem’s Outright 770: A One-Drum Performance Booster
VicChem’s Outright 770 Spray Adjuvant is designed to simplify the mixing process without sacrificing herbicide performance. Used at 0.5-1%, Outright has shown significant improvements in the effectiveness of:
- Glyphosate
- Ester 680
- Triclopyr (Garlon)
- Oxyfluorfen (Striker/Goal)
- And several other commonly used knockdown herbicides
It’s essentially a “best of all worlds” formulation that saves time while giving a more reliable result in the paddock.
What’s Inside Outright 770?
Outright brings together three functional components that each play a key role in improving herbicide uptake and activity.
1. Methyl Oleate – The Penetrating Oil
- Helps active ingredients move through the waxy cuticle of weeds
- Slows droplet evaporation, allowing more time for foliar uptake
- Improves penetration in tough, stressed, or hard-to-wet weeds
2. Non-Ionic Surfactants – Better Wetting & Spreading
Similar to LI700, these surfactants help droplets:
- Stick to the leaf
- Spread across the surface
- Deliver more active ingredients where it counts
3. Ammonium Sulphate – Protection Against Hard Water
AMS helps:
- Reduce hard water antagonism, particularly in glyphosate
- Improve herbicide absorption
- Minimise incompatibility issues in more complex tank mixes
What are the Key Benefits for Growers?
Using Outright 770 delivers several practical, measurable advantages:
- Improved penetration of herbicides through waxy weed cuticles
- Slower dry-down, extending uptake time
- Better droplet retention on leaf surfaces
- Enhanced spreading and wetting for greater coverage
- Protection against hard water deactivation, especially for glyphosate
- Stable, easy-mix formulation with reliable emulsion characteristics
- Saves time by removing the need to juggle multiple products
- Developed in Australia, specifically for local conditions
- Patented formulation ensuring consistency and performance
Compatibility: A Very Easy Mixer
One of the major drawcards is how reliably Outright 770 mixes with common knockdown chemistry. It is compatible with:
- Glyphosate formulations
- 2,4-D & Nufarm Dropzone
- Triclopyr (Garlon)
- Paraquat & Diquat
- Clopyralid (Lontrel/Archer)
- Oxyfluorfen (Goal/Striker)
- Carfentrazone (Hammer/Nail)
This gives growers confidence when mixing complex tank mixes during tight spraying windows.
