Q1: Nevada Category C1 Limited Landscape definition?
A. Aquatic weeds lakes only
B. Bare ground total vegetation control industrial sites only
C. Agricultural crops alfalfa wheat corn only
D. Limited landscape pest control - insects, diseases, weeds in ornamental landscape, turfgrass, limited to ornamental and turf areas
- not agricultural crops, not bare ground sterilants - includes ornamental beds, trees, shrubs, lawns
Answer & ULTRA-Detailed Rationale:
D. Limited landscape pest control - insects, diseases, weeds in ornamental landscape, turfgrass, limited to ornamental and turf
areas - not agricultural crops, not bare ground sterilants - includes ornamental beds, trees, shrubs, lawns
CONCEPT: Scope C1 Limited Landscape. CORRECT - A: C1 Limited Landscape per Nevada Dept Agriculture NDA: control of
insects, diseases, weeds in ornamental landscape and turfgrass - limited to ornamental beds, trees, shrubs, lawns, turf areas
around buildings, parks, golf course ornamentals. Not agricultural crops (B categories), not bare ground sterilant total vegetation
control (C6), not aquatic (C5). Ground equipment backpack, spray rig, spreader. Requires knowledge ornamental tolerance, turfgrass,
IPM. WHY B WRONG: Agricultural crops alfalfa wheat corn is Category B1/B2 Agricultural - not urban structural C1 - different label sites,
different regulations - C1 is ornamental turf. WHY C WRONG: Bare ground total vegetation control industrial sites is C6 Weeds - not C1 -
C6 is bare ground sterilants industrial ROW - C1 is ornamental turf selective weed control, not total vegetation. WHY D WRONG:
Aquatic weeds lakes is Category C5 Aquatic - not C1 - C1 is terrestrial ornamental turf. EXAM TIP: C1 = ornamental landscape + turf -
insects diseases weeds in landscape - not bare ground - not ag - memorize limited landscape = ornamentals and turf.
Q2: Turfgrass weeds - crabgrass vs annual bluegrass vs dandelion control timing C1?
A. Crabgrass winter annual
B. All weeds same timing same herbicide
C. Dandelion annual only
D. Crabgrass summer annual preemergence prodiamine pendimethalin in spring before soil temp 55F - annual bluegrass winter
annual pre fall - dandelion perennial broadleaf postemergence 2,4-D fall best when translocating to roots
Answer & ULTRA-Detailed Rationale:
D. Crabgrass summer annual preemergence prodiamine pendimethalin in spring before soil temp 55F - annual bluegrass
winter annual pre fall - dandelion perennial broadleaf postemergence 2,4-D fall best when translocating to roots
CONCEPT: Turf weed timing. CORRECT - A: Crabgrass Digitaria summer annual germinates spring when soil temp 55F 3 days -
control preemergence prodiamine, pendimethalin, dithiopyr in spring before germination or early post with quinclorac small.
Annual bluegrass Poa annua winter annual germinates fall - control pre fall or ethofumesate. Dandelion Taraxacum perennial
broadleaf - control postemergence 2,4-D, triclopyr, MCPP fall best when sugars moving to roots - spring also works but fall
superior for perennials. WHY B WRONG: All weeds same timing same herbicide false - life cycles differ - summer annual pre spring,
winter annual pre fall, perennial post fall - different herbicides. WHY C WRONG: Crabgrass summer annual not winter annual - reverse -
crabgrass germinates spring not fall. WHY D WRONG: Dandelion perennial not annual only - perennial taproot extensive - annual would
be easy - perennial needs systemic fall. EXAM TIP: Summer annual pre spring, winter annual pre fall, perennial broadleaf post fall best.

,Q3: Selective herbicide in turf - 2,4-D vs dicamba vs triclopyr tolerance?
A. Kill turfgrass and broadleaf same
B. Only kill grass not broadleaf
C. 2,4-D, dicamba, triclopyr are auxin mimics Group 4 broadleaf weed killers selective in turfgrass - turfgrass monocot tolerant,
broadleaf weeds dicot susceptible - avoid drift to ornamentals sensitive - amine less volatile than ester
D. No selectivity
Answer & ULTRA-Detailed Rationale:
C. 2,4-D, dicamba, triclopyr are auxin mimics Group 4 broadleaf weed killers selective in turfgrass - turfgrass monocot tolerant,
broadleaf weeds dicot susceptible - avoid drift to ornamentals sensitive - amine less volatile than ester
CONCEPT: Broadleaf selective in turf. CORRECT - A: 2,4-D, dicamba, triclopyr, MCPP auxin mimics Group 4 selective broadleaf
weed killers in turfgrass - turfgrass (monocot) tolerant due to metabolism and morphology, broadleaf weeds (dicot)
susceptible - epinasty twisting. Must avoid drift to sensitive broadleaf ornamentals, tomatoes, grapes - amine less volatile than ester
- ester more volatile drift damage. WHY B WRONG: Kill turfgrass and broadleaf same would be non-selective glyphosate - not selective
- selective spares turfgrass. WHY C WRONG: Only kill grass not broadleaf reversed - these kill broadleaf not grass - grass herbicides
like sethoxydim kill grass not broadleaf. WHY D WRONG: No selectivity false - selectivity exists - monocot vs dicot difference. EXAM
TIP: Broadleaf weed killers selective in turf - but will damage ornamentals - buffer zones - amine less volatile than ester - ester more
volatile - exam tests amine vs ester.
Q4: Ornamental insects - aphids vs spider mites vs scale control C1?
A. No control needed ornamentals
B. Aphids small soft-bodied sucking honeydew - control horticultural oil, insecticidal soap, systemic imidacloprid - spider mites not
insects arachnids webbing stippling - control miticide abamectin horticultural oil avoid broad-spectrum that kills predators - scale
armored immobile - control dormant oil crawler stage
C. Same control all pests one spray
D. All insects same
Answer & ULTRA-Detailed Rationale:
B. Aphids small soft-bodied sucking honeydew - control horticultural oil, insecticidal soap, systemic imidacloprid - spider
mites not insects arachnids webbing stippling - control miticide abamectin horticultural oil avoid broad-spectrum that kills
predators - scale armored immobile - control dormant oil crawler stage
CONCEPT: Ornamental insect ID. CORRECT - A: Aphids small soft-bodied sucking produce honeydew sooty mold - many
species - control horticultural oil, insecticidal soap, strong water spray, systemic imidacloprid, conserve predators lady
beetles. Spider mites Tetranychus not insects arachnids 8 legs webbing stippling yellow dots - control miticide abamectin,
bifenazate, horticultural oil, avoid broad-spectrum pyrethroids that kill predatory mites causing flare. Scale armored immobile
on stems - control dormant oil winter, crawler stage most vulnerable with oil or systemic, timing critical crawler emergence.
WHY B WRONG: Same control one spray fails - aphids soft-bodied need soap/oil, mites need miticide not insecticide, scale needs
dormant oil crawler timing - different. WHY C WRONG: All insects same false - mites are arachnids not insects - different control -
insecticide may not kill mites. WHY D WRONG: No control needed false - ornamental pests cause aesthetic damage, plant death - must
control. EXAM TIP: Mites are not insects - insecticide may flare mites by killing predators - use miticide and oil.

A. Diseases only in winter
B. Brown patch Rhizoctonia warm humid nights above 68F - dollar spot small dollar size spots - powdery mildew shade humid -
control cultural reduce thatch, improve drainage, avoid night watering, fungicide chlorothalonil propiconazole if needed
C. No cultural control only fungicide always
D. All diseases same conditions same control
Answer & ULTRA-Detailed Rationale:
B. Brown patch Rhizoctonia warm humid nights above 68F - dollar spot small dollar size spots - powdery mildew shade humid
- control cultural reduce thatch, improve drainage, avoid night watering, fungicide chlorothalonil propiconazole if needed
CONCEPT: Turf disease. CORRECT - A: Brown patch Rhizoctonia solani warm humid nights above 68F circular brown patches -
dollar spot Clarireedia small silver dollar size spots - powdery mildew Erysiphe shade humid white powder - control cultural:
reduce thatch aeration, improve drainage, avoid night watering water morning, proper nitrogen not excess, fungicide
chlorothalonil, propiconazole, azoxystrobin if needed but cultural first per IPM. WHY B WRONG: All diseases same conditions
false - brown patch warm humid, powdery mildew shade - different. WHY C WRONG: No cultural only fungicide always false - cultural
primary per IPM - fungicide last resort - cultural reduces disease pressure. WHY D WRONG: Diseases not only winter - brown patch
summer warm - many summer diseases. EXAM TIP: Cultural first: reduce thatch, improve drainage, morning watering not night.
Q6: Ornamental trees - borers vs bark beetles - IPM C1?
A. No prevention healthy trees still attacked same
B. Only cut tree down no other control
C. Only spray foliage
D. Borers larvae tunneling under bark in stressed trees - bark beetles mass attack - control keep trees healthy water mulch avoid
wounding - insecticide preventive trunk spray permethrin timing adult flight - systemic imidacloprid for some borers
Answer & ULTRA-Detailed Rationale:
D. Borers larvae tunneling under bark in stressed trees - bark beetles mass attack - control keep trees healthy water mulch
avoid wounding - insecticide preventive trunk spray permethrin timing adult flight - systemic imidacloprid for some borers
CONCEPT: Tree borers. CORRECT - A: Borers e.g., emerald ash borer, bronze birch borer larvae tunneling under bark cambium
in stressed trees - bark beetles e.g., ips engraver mass attack - control IPM: keep trees healthy proper watering mulching avoid
wounding, prune, insecticide preventive trunk spray permethrin bifenthrin timing adult flight before egg laying, systemic
imidacloprid emamectin for some borers injected. WHY B WRONG: Only cut tree down no other control false - prevention keeping
healthy and preventive sprays work - cutting only last resort if dead. WHY C WRONG: No prevention false - healthy trees resist borers -
stressed trees attract - keeping healthy primary. WHY D WRONG: Only spray foliage insufficient - borers under bark - need trunk spray
preventive. EXAM TIP: Healthy tree best defense against borers - avoid wounding - preventive trunk spray timing adult flight.

B. No label needed use any rate
C. All preemergence kill ornamentals always
D. Oryzalin Surflan, pendimethalin Pendulum, prodiamine Barricade, isoxaben Gallery preemergence in ornamental beds - control
annual weeds prevent germination - must be labeled for ornamentals - tolerant ornamentals list on label - avoid sensitive ornamentals
Answer & ULTRA-Detailed Rationale:
D. Oryzalin Surflan, pendimethalin Pendulum, prodiamine Barricade, isoxaben Gallery preemergence in ornamental beds -
control annual weeds prevent germination - must be labeled for ornamentals - tolerant ornamentals list on label - avoid
sensitive ornamentals
CONCEPT: Preemergence in ornamental beds. CORRECT - A: Oryzalin Surflan, pendimethalin Pendulum, prodiamine Barricade,
isoxaben Gallery, dithiopyr Dimension preemergence in ornamental beds - control annual grasses and broadleaves prevent
germination - must be labeled for ornamentals and specific ornamental species tolerant - read label tolerant ornamentals list -
avoid sensitive species - apply before weed emergence needs water activation - does not control emerged weeds. WHY B
WRONG: No preemergence only post false - preemergence widely used in ornamental beds to prevent annual weeds - reduces hand
weeding. WHY C WRONG: All preemergence kill ornamentals always false - many ornamentals tolerant to specific preemergence -
selectivity exists - label lists tolerant species. WHY D WRONG: No label needed use any rate false - must follow label rate and tolerant
ornamentals - using off-label rate or on sensitive ornamental causes injury liability. EXAM TIP: Read label tolerant ornamentals list - if
ornamental not listed, don't use or test small area.
Q8: Calibration - spreader and sprayer for turf ornamental C1?
A. Only sprayer needs calibration spreader no
B. Only spreader needs calibration sprayer no
C. Calibration critical - spreader: measure area, weigh material used, calculate rate - sprayer backpack GPA - uniform coverage
within 10 percent - underdose poor control resistance overdose ornamental injury turf burn illegal
D. No calibration needed guess
Answer & ULTRA-Detailed Rationale:
C. Calibration critical - spreader: measure area, weigh material used, calculate rate - sprayer backpack GPA - uniform coverage
within 10 percent - underdose poor control resistance overdose ornamental injury turf burn illegal
CONCEPT: Calibration. CORRECT - A: Calibration: spreader - measure 1000 sq ft, weigh material used, calculate rate per 1000 sq
ft - adjust setting. Sprayer GPA = GPM times 5940 / (MPH times spacing) - backpack spray measured area water used. Uniform
within 10 percent - underdose poor control selects resistant weeds, overdose ornamental injury turf burn phytotoxicity illegal
per label rate - violates FIFRA label is law. WHY B WRONG: No calibration guess violates label - must apply per label rate - guessing
causes failure or injury - illegal. WHY C WRONG: Only spreader needs calibration false - sprayer also needs calibration. WHY D
WRONG: Only sprayer needs calibration false - spreader also needs. EXAM TIP: Must calibrate both spreader and sprayer - label rate
law.
