Washington Pesticide Laws and Safety Exam
Questions With Correct Answers
What |is |a |severe |pest? |- |CORRECT |ANSWER✔✔-A |pest |present |in |populations |that |are |always |
above |the |economic |injury |level |in |the |absence |of |control.
What |is |an |occasional |or |secondary |pest? |- |CORRECT |ANSWER✔✔-A |pest |that |can |cause |
damage |above |economic |injury |levels |only |at |certain |times.
What |is |a |potential |pest? |- |CORRECT |ANSWER✔✔-A |pest |that |typically |causes |no |apparent |
economic |damage |under |normal |circumstances.
What |is |a |migratory |pest? |- |CORRECT |ANSWER✔✔-A |pest |that |may |cause |serious |economic |
damage |on |a |periodic |basis.
What |are |the |five |steps |of |developing |an |IPM |program? |- |CORRECT |ANSWER✔✔-1. |Identify |
the |pest |to |be |managed. |
2. |Define |the |management |system.
3. |Develop |the |pest |management |strategy. |
4. |Develop |reliable |monitoring |techniques. |
5. |Use |economic |thresholds.
What |is |an |economic |threshold? |- |CORRECT |ANSWER✔✔-The |level |or |density |of |a |pest |
population |where |control |measures |need |to |be |applied |to |prevent |the |pest |from |reaching |the |
economic |injury |level.
What |is |an |economic |injury |level? |- |CORRECT |ANSWER✔✔-The |pest |population |density |that |
causes |losses |equal |to |the |cost |of |the |control |measures.
,What |are |mechanical |control |methods? |- |CORRECT |ANSWER✔✔-Devices |that |prevent |the |
spread |or |reduce |the |infestation |of |pests, |primarily |insects |and |vertebrate |animals. |
Mechanical |controls |include |hand |destruction, |traps, |and |mechanical |exclusions |such |as |
screens, |nets, |and |fences.
What |are |physical |control |methods? |- |CORRECT |ANSWER✔✔-The |manipulation |of |water, |
humidity, |temperature, |electric |shock, |or |other |radiant |energy |to |kill, |alter |the |pests |life |cycle, |
or |create |an |unfavorable |environment |for |the |pest |to |live |in.
What |are |cultural |control |methods? |- |CORRECT |ANSWER✔✔-The |manipulation |of |the |
environment |to |avert |serious |pest |damage. |Cultural |control |methods |require |knowledge |of |the
|plants |needs |and |potential |problems. |Ex: |irrigation |management, |rotating |crops, |pruning, |
cover |crops, |etc.
What |are |generic |control |methods? |- |CORRECT |ANSWER✔✔-The |use |of |plants |and |animals |
that |are |resistant |to |attack |by |pests. |Ex: |Traditional |breeding |techniques |combined |with |
genetic |manipulation |of |plants |to |promote |host |plant |resistance |to |pests |and |disease.
What |are |biological |control |methods? |- |CORRECT |ANSWER✔✔-Involve |the |introduction, |
encouragement, |and/or |artificial |increase |of |plants |and |insects/animals |that |are |parasites |or |
predators |of |a |pest |species.
What |are |chemical |control |methods? |- |CORRECT |ANSWER✔✔-Involve |the |use |of |naturally |or |
synthetically |derived |chemicals |that, |kill, |attract, |repel, |or |otherwise |manage |the |growth |of |a |
pest.
Avicides |- |CORRECT |ANSWER✔✔-Management |of |birds.
Bactericides |- |CORRECT |ANSWER✔✔-Management |of |bacteria.
, Fungicides |- |CORRECT |ANSWER✔✔-Management |of |fungi.
Herbicides |- |CORRECT |ANSWER✔✔-Management |of |plants.
Insecticides |- |CORRECT |ANSWER✔✔-Management |of |insects |and |insect |relatives.
Miticides |- |CORRECT |ANSWER✔✔-Management |of |mites.
Molluscicides |- |CORRECT |ANSWER✔✔-Management |of |snails |and |slugs.
Nematicides |- |CORRECT |ANSWER✔✔-Management |of |nematodes.
Piscicides |- |CORRECT |ANSWER✔✔-Management |of |pest |fish.
Rodenticides |- |CORRECT |ANSWER✔✔-Management |of |rodent |populations.
Although |not |considered |pesticides |by |definition, |what |three |classes |of |chemicals |are |also |
regulated |and |classified |as |such? |- |CORRECT |ANSWER✔✔-1. |Defoliants: |Chemicals |that |cause |
leaves |or |foliage |to |drop |from |a |plant. |
2. |Dessicants: |Chemicals |that |promote |drying |or |loss |of |moisture |in |plant |tissues. |
3: |Growth |Regulators: |Substances |(other |than |fertilizers |or |food) |that |alter |the |growth |or |
development |of |a |plant |or |animal.
Adjuvants |are |regulated |as |pesticides |in |Washington |state. |What |are |adjuvants? |- |CORRECT |
ANSWER✔✔-Substances |added |to |the |pesticides |formulations |and |tank |mixtures |to |increase |
safety |or |effectiveness.
