B. No definition
C. Only dermal
D. Dose kills 100%
Answer & Excellent Rationale:

A. Lethal Dose 50% - dose that kills 50% of test population - lower LD50 = more toxic

Rationale: CORRECT: LD50 lethal dose 50% kills 50% test animals mg/kg body weight - lower LD50 more toxic more hazardous. LD50 oral vs
dermal vs inhalation LC50. WHY WRONG: B 100% LD100 not LD50. C definition exists critical toxicity. D oral dermal inhalation all have LD50 LC50.



Q7: PPE required where found?
A. Only employer decides
B. No PPE needed
C. Only gloves always
D. On pesticide label in Precautionary Statements section - must follow label PPE - minimum label plus Nevada WPS requirements
Answer & Excellent Rationale:

D. On pesticide label in Precautionary Statements section - must follow label PPE - minimum label plus Nevada WPS requirements

Rationale: CORRECT: PPE Personal Protective Equipment required listed on label Precautionary Statements Hazards to Humans - must wear
label-required PPE - coveralls, gloves type chemical resistant, eyewear, respirator if required. Plus WPS Worker Protection Standard may require
more. WHY WRONG: B PPE required many pesticides. C employer must provide but label dictates. D gloves not always but many require more.



Q8: Chemical resistant gloves type for most agricultural pesticides?

,Q9: REI Restricted Entry Interval definition?
A. Time after application during which entry into treated area limited without PPE - on label and WPS - must post signs oral notification
B. Only 1 hour
C. No REI
D. Only for fungicides
Answer & Excellent Rationale:

A. Time after application during which entry into treated area limited without PPE - on label and WPS - must post signs oral notification

Rationale: CORRECT: REI Restricted Entry Interval time after application no entry without PPE early entry allowed only for limited tasks with PPE -
on label Agricultural Use Requirements box - must post warning signs and oral notification to workers per WPS Worker Protection Standard. WHY
WRONG: B REI exists critical worker safety. C varies 4 hr to 30+ days not only 1 hr. D all pesticides not only fungicides.



Q10: WPS Worker Protection Standard applies to?
A. Agricultural workers and pesticide handlers on agricultural establishment farms nurseries forests - requires training decontamination REI
notification
B. No workers
C. Only factories
D. Only homeowners
Answer & Excellent Rationale:

A. Agricultural workers and pesticide handlers on agricultural establishment farms nurseries forests - requires training decontamination
REI notification

Rationale: CORRECT: WPS EPA Worker Protection Standard 40 CFR 170 applies to ag workers pesticide handlers on farms forests nurseries
greenhouses - requires training annually, decontamination supplies water soap towels, REI enforcement, notification posting, emergency
assistance. WHY WRONG: B ag not factories. C workers protected. D homeowners not WPS.



Q11: Drift minimization techniques ground boom?
A. No drift control needed
B. High boom 6 ft high wind fine
C. Only small droplets best
D. Use low drift nozzles air induction, lower boom height 18-24 inches, larger droplet size, avoid high wind >10 mph temperature inversion,
buffer zones
Answer & Excellent Rationale:

D. Use low drift nozzles air induction, lower boom height 18-24 inches, larger droplet size, avoid high wind >10 mph temperature
inversion, buffer zones

Rationale: CORRECT: Drift minimization: low drift nozzles air induction AI produce large droplets less drift, boom height 18-24 inches target, larger
droplet size classification ASABE coarse very coarse, wind 3-10 mph ideal avoid <3 inversion and >10 drift, buffer zones downwind sensitive areas,
use drift retardant adjuvant if label allows. WHY WRONG: B high boom increases drift high wind increases drift. C drift control critical Nevada
sensitive areas. D small droplets drift more.



Q12: Temperature inversion and spraying?
A. Only affects aerial
B. No effect
C. Do not spray during inversion - inversion occurs low wind clear skies cool evening temperature increases with height traps small droplets
suspends causes long distance drift
D. Spray during inversion best
Answer & Excellent Rationale:

C. Do not spray during inversion - inversion occurs low wind clear skies cool evening temperature increases with height traps small
droplets suspends causes long distance drift

Rationale: CORRECT: Inversion occurs early morning evening clear skies low wind <3 mph temp increases with height - stable air prevents mixing
small droplets suspended drift long distances - do not spray during inversion - indicators dust hangs, fog, dew, distant sounds smells. WHY
WRONG: B inversion worst time to spray causes severe drift. C effect major. D ground and aerial both affected.

, Q13: Nozzle type for systemic herbicide vs contact fungicide?
A. Systemic herbicide larger droplet coarse to reduce drift contact with leaf sufficient, contact fungicide medium smaller droplet thorough
coverage needed but still drift control
B. Contact needs largest
C. Same nozzle always
D. Systemic needs finest
Answer & Excellent Rationale:

A. Systemic herbicide larger droplet coarse to reduce drift contact with leaf sufficient, contact fungicide medium smaller droplet thorough
coverage needed but still drift control

Rationale: CORRECT: Systemic herbicide translocated in plant larger droplet coarse enough coverage systemic movement - drift control priority.
Contact fungicide needs thorough coverage of leaf surface medium droplet better coverage but balance drift. WHY WRONG: B different needs
coverage vs drift. C systemic finest drifts more not needed systemic translocation. D contact needs medium not largest.



Q14: Calibration - GPM formula for boom sprayer?
A. GPA = GPM only
B. No formula
C. GPA = MPH only
D. GPA = GPM per nozzle * 5940 / MPH * nozzle spacing inches - example 0.5 GPM 6 MPH 20 inch spacing = 24.75 GPA
Answer & Excellent Rationale:

D. GPA = GPM per nozzle * 5940 / MPH * nozzle spacing inches - example 0.5 GPM 6 MPH 20 inch spacing = 24.75 GPA

Rationale: CORRECT: Boom calibration: GPA gallons per acre = GPM per nozzle x 5940 / (MPH x W nozzle spacing inches). 5940 constant
conversion. Must calibrate each nozzle check uniformity 10% variation replace. WHY WRONG: B formula exists critical accurate application rate.
C/D incomplete - need all three GPM MPH spacing.



Q15: Pesticide mixing - PPE and order?
A. No order
B. Add EC first always
C. No PPE mixing
D. Wear PPE label requires, fill tank 1/2 water, add adjuvant if needed, add dry formulations WP DF first, then liquid flowables, then EC, then
surfactant last, fill remaining water - triple rinse containers
Answer & Excellent Rationale:

D. Wear PPE label requires, fill tank 1/2 water, add adjuvant if needed, add dry formulations WP DF first, then liquid flowables, then EC,
then surfactant last, fill remaining water - triple rinse containers

Rationale: CORRECT: Mixing PPE especially during mixing loading highest exposure - wear label PPE including face shield apron gloves respirator
if required. Mixing order W-A-L-E-S: Water half, Agitate, dry formulations WP DF, Liquid flowables, EC emulsifiable concentrate, Surfactant adjuvant
last - prevents compatibility issues gelling. Triple rinse containers. WHY WRONG: B mixing highest exposure need PPE. C EC first may cause
gelling with dry. D order matters compatibility.



Q16: Chemigation in Nevada requires?
A. Only injection pump needed
B. No permit needed
C. No backflow devices
D. Chemigation permit from Nevada Division Environmental Protection NDEP plus anti-pollution devices: check valve, vacuum relief, low
pressure drain, interlock, injection check valve per NAC 445A
Answer & Excellent Rationale:

D. Chemigation permit from Nevada Division Environmental Protection NDEP plus anti-pollution devices: check valve, vacuum relief, low
pressure drain, interlock, injection check valve per NAC 445A
