 Suitable for ground or aerial application
 Low or high volume spray rates
The Adjuvant Advantage
…in the mix tank
…between the spray tip and the leaf
Strong Chelating Agents
- Ensures the water
solubility required
for plant uptake and
utilization.
Anti-Evaporants - Achieves greater efficiency of the applied
nutrients by preventing the evaporation of micro-droplets
before the target is reached.
Buffering Agents - Improves
stability of the spray
solution and provides
optimum nutrient
availability when tank
mixing with many
common crop protection
products.
Miscibility - Application
and handling efficiencies
result from tank mixing
WUXAL formulations
with many common crop
protection products.
…on the leaf
Surfactants - Evenly
distributes the spray
solution on leaf
surface to maximize
efficacy and crop
safety of foliar applied
nutrients.
Stickers - Greatly
reduces nutrient
wash- off loss due
to irrigation and
rainfall by holding
the solution on the
targeted leaf surface.
Humectants –
Re-activates dried
residual deposits,
allowing for plant
uptake over a
prolonged time
period.
