Dermal vs Oral Exposure
Dermal
- Most common applicator
- Skin absorption
- Gloves prevent
Oral
- Accidental ingestion
- Most common poisoning
- Label storage prevents
Work vs accident

- Then dispose
Environmental Controls
- Drift
- Off-target movement
- Inversion

GPA Formula
GPA = GPM x 5940 / mph / spacing
GPM: nozzle outputmph: travel speedSpacing: inches
Calibration vs Application
Calibration
- Verify GPA
- Measure output
- Before season
Application
- Actually spray
- Follow rate
- In the field
Setup vs use
Nozzle & Spray Picker
- Canopy coverage needed→Hollow cone(Insecticide/fungicide)
- Broadcast herbicide→Flat fan(Uniform pattern)
- Drift risk high→Drift-reduction nozzle(Coarse droplets)
- Spot treatment→Handgun(Small area)
- Band application→Even flat fan(Banded row)
- Foliage penetration→Hollow cone(Underside coverage)
Calibration Math
- GPA
- Gallons per acre
- GPM
- Nozzle output
- mph
- Travel speed
- 5940
- Formula constant
- 2x speed
- GPA halved
- High pressure
- Droplets finer
- Agitation
- Keep suspensions mixed
Nozzles & Equipment
- Hollow cone
- Canopy coverage
- Flat fan
- Broadcast herbicide
- Regulator
- Uniform spray
- Drift-reduction
- Coarse droplets
- Boom height
- Minimum overlap
- 3-10 mph
- Safe spray wind
- Anemometer
- Measure actual wind
Restricted vs General Use
RUP
- Certified only
- May harm even labeled
- EPA restricts
General Use
- Anyone can buy
- Lower risk
- No certification
Certification needed
Pesticide Types
- RUP
- Certified applicator only
- General use
- Anyone can buy
- Selective
- Targets specific weeds
- Non-selective
- Kills all vegetation
- Pre-emergent
- Soil barrier
- Post-emergent
- Growing weeds
- SP/SL
- True solution
Selective vs Non-Selective
Selective
- Targets weed types
- Crop safe
- Broadleaf or grassy
Non-Selective
- Kills all plants
- Glyphosate example
- Spot or bare ground
Target vs all
Pre vs Post-Emergent
Pre-emergent
- Soil barrier
- Before germination
- Incorporate needed
Post-emergent
- Growing weeds
- After emergence
- Contact or systemic
Before vs after
Common Traps
Label vs supervisor
Label governs application ≠ Supervisor cannot override
REI vs PHI
REI protects workers ≠ PHI protects harvest
RUP vs general use
RUP needs certification ≠ General use anyone buys
Speed vs rate
Double speed halves GPA ≠ Nozzle output unchanged
Pressure vs droplet
Higher pressure finer droplets ≠ More drift risk
Pre vs post emergent
Pre before germination ≠ Post after emergence
