DEPOSITION AND
CANOPY PENETRATING AID
Features and Benefits
• Unique modified seed oil formulation
– Slows drying time allowing the pesticide
more time to work
– Emulsifies easily in water with pesticides
– May be used with most any type of
nozzles, including air induction and other
fine reducing nozzles
Features and Benefits
• Spray droplet management
– Provides more uniform droplet sizes
– Manipulates the full droplet spectrum
– Reduces small droplets that can drift
– Minimizes chemical trespass
– Speeds the droplet to the target
Droplet size across a Range
Ideal range to decrease drift is 300 to 500 microns

Features and Benefits
• Increased Deposition (spray deposit)
– Gets more droplets on target
– Improves coverage
– Better penetration of the crop canopy
Note: All factors, including the condition and settings of the
equipment and wind speed and direction, humidity and
temperature must all be taken into account to properly
manage deposition.
