GRAVITATE 707 Spray Adjuvant
Product Description
Gravitate 707 is an acidifying and penetrating adjuvant for use with agrichemical products.
Gravitate 707 Spray Adjuvant is a second generation acidifying and penetrating surfactant,
specifically designed and manufactured for Australian conditions. Gravitate 707 includes the
proven power of Hasten for superior weed leaf penetration and reduced driftable fines,
resulting in more spray droplets hitting and penetrating into target weeds†
.
Gravitate 707 offers a low odour for improved handling and a pH indicator, helping growers
and spray operators to confirm the ideal pH in a tank mix.
Product Performance
Gravitate 707 has been trialled extensively, demonstrating effective weed control when
compared to VC700. The Trials used average glyphosate rates with 0.25 and 0.5% Gravitate
707 in rain and hard water (500ppm).

Product Usage
Rates
For Glyphosate and Glyphosate mixes, use 250 – 500mL/100L to optimise the spray water pH
and assist spreading and penetration and reduce off-target damage.
Mixing
Half fill the spray tank with water and commence agitation. Add the required quantity of
GRAVITATE 707 then add the recommended quantity of herbicide. Maintain agitation until
completion of spraying.
When mixing dry granules, add granules to tank first and make sure they have completely
dissolved before adding Gravitate 707
Key Points
Wetting, Spreading and Penetrating
Gravitate 707 surfactant helps spray droplets
Adhere to leaf surface
Spread across leaf surface
Penetrate into the target weed
Droplet Management
Gravitate 707 when applied with Glyphosate and
2,4-D products significantly reduced the amount of
driftable fines (<150um) produced from hydraulic
nozzles when compared with the wetting agent
Surewet 1000 and was similar or better at reducing
driftable fines when compared with the low drift
adjuvants VC-700† and Deadsure?
Note: Spray drift is a result of multiple environmental
and application factors, importantly all need to be
considered when making spraying decisions.
The importance of managing pH
The acidifying nature of Gravitate 707
buffers spray tank water to a pH range
of 4-5, ideal for herbicides including
Glyphosate.
To validate this ideal pH range, Gravitate
707 has a pH indicator in its formulation.
The pH Indicator will change the tank
mix to a pink/red colour at a pH range
below 5.
