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.

Alfalfa Nutrition
Deficiency Symptoms
Phosphorous (P)
Energy transfer and storage
Root, flower and seed production
Hastens maturity
•Stunting and upward tilting of leaflets
•Short spindly stems
•Dark green or purplish leaves; tip death
in some cases
•Reduced nodulation and increased
winter kill
Potassium (K)
Plant enzyme activator
Sugar formation, protein synthesis
Cell division
Cold stress tolerance
•Stunting
•Leaves show chlorotic speckling/burning
around the margins
•Short spindly stems
•Increased winter kill
Facilitates carbohydrate movement
and translocation for re-growth after
each cutting and seed production
•Stunting
•Reddish/yellowish coloration on upper
leaf canopy
•Leaves show chlorotic speckling/burning
around the margins
•Short spindly stems
•Terminal bud death
Boron (B)
