Wisconsin 7.1 Flashcards
How long does the American Cockroach get?
1.5 Inches
What is a pest?
Pests compete with people for food, shelter, and cause economic or structural damage.
Does a moth undergo Complete or Incomplete metamorphosis?
Complete
Are baiting programs effective at pest control?
Yes, baiting is very effective for many pest control needs, when combined with other strategies.
Where do Carpenter Ants nest?
In old logs, stumps, under porch footings.
Why would you prebait a station?
To overcome bait shyness/Neophobia
How well do rodents see?
Not very well. They use touch smell and sound.
Where would you place a locked bait station?
Anywhere that could possibly be accessed by children or any non target animals.
What agency regulates birds?
US Fish and Wildlife Service
What is the issue caused by birds in grain facilities?
They eat the grains and spoil them with defecation
Why would you do a perimeter application to control weeds?
To remove harborage for pests for easier control.
When should you apply grain protectant?
Before infestation
What is the difference between trade name and common name for an active ingredient?
The trade name is a specific formulation. The common name is just the active ingredient.
Can persistent pesticides move off target?
Yes
What are the consequences of a pesticide drifting off target?
Local ecosystems can be damaged, and you can be held liable.
What supersedes a pesticide label?
Federal law
What should you do if exposed to chemical?
Remove affected clothing. Wash area. Seek medical attention if needed.
Who do you call in Wisconsin for a chemical spill?
Wisconsin DNR
Who oversees registration of the use or uses of a pesticide?
The EPA
What do you do to get a larger flow rate with a nozzle?
Use a larger nozzle
How long is a for hire pest control certification good for? How long is the License good for?
Certification 5 years. License 1 year.
When do you notify a resident of chemical application?
Before and after application
How do you control pesticide waste?
Only mix what you need/intend to use.
Disadvantages of solid bait?
Can be moved off target. Can break down in elements.
Is proper identification important to pest control? If so, why?
Yes, if you dont properly ID the pest you cannot select the proper product and treatment to solve it.
When should you use a respirator?
When advised by the label.
How do you achieve a larger flow rate with a nozzle?
Change nozzle or amount of pressure.
What are the components of a pest control record?
Name of applicator
Name and address of customer
The crop, commodity, or specific site treated
A specific description of the site treated
The full date and approximate start and end time of application
The product name and EPA reg number
Either the Concentration and total quantity of each pesticide applied, or, the amount of each pesticide applied per unit area and the total area treated
How long do you keep pest control records?
Minimum 2 years
What are the 3 C’s of a chemical spill?
Control, Contain, Clean
What is “Ultra Low Volume”?
High concentration applications at reduced rates of application. (Droplets of 1-30 micron size)
What is the Hazard Communication System designed to do?
Protect employees who handle or use hazardous chemicals
What is the difference/give examples of between local and systemic effects?
Local effects only harm what actually touch. Systemic effects will cause damage elsewhere than just the entry point.
Explain acute and delayed effects
Acute effects happen usually within minutes or hours of exposure to toxic substance.
Delayed effects could appear weeks, months, or even years later. Usually from long term repeated exposure
List the four routes pesticides enter the body
Dermal
Oral
Inhalation
Eyes
Describe the relationship between a pesticides toxicity and its LD50
LD50 is the amount of pesticide that kills half the subjects. The lower the LD50, the more toxic the product.
Describe some general symptoms of pesticide exposure
Fatigue, headache, weakness, dizziness, trembling, blurred vision, flushed or yellow skin, fever, intense thirst, convulsions
What is a pesticide?
Any substance used to control pest populations to prevent or reduce pest damage.
What is the difference between anti coagulant and acute rodenticides?
Anticoagulants cause death by inhibiting certain blood functions. (Diphacinone, warfarin, brodifacoum, bromadiolone)
Acute rodenticides are not anticoagulants, and toxic in their own way. (Bromethalin, cholecalciferol, strychnine)
Explain the difference between the different types of pesticide names
Trade Name: manufacturer given to specific formulations
Chemical Name: each active ingredient is given a chemical name that complies with accepted standards established by chemists.
Common Name: active ingredient assigned Name, meant for regular usage. (ß-Cyfluthrin) Same a.i. no matter who produces specific product.
What ways can a pesticide move from site of application?
Volatilize (gas off), be rinsed off a treated surface into soil, be carried laterally by runoff or corrosion, leech through soil, be ingested by animal that eats pest treated with pesticide, overspray, drift.
Define overspray and drift.
Overspray is the application of pesticide beyond the boundaries of the target area. It is considered a negligent action.
Drift is movement of pesticide in air currents or by diffusion onto property beyond the boundaries of the target area. It may be solid, or vapors, or liquid particles.
Explain Wisconsin law regarding overspray and drift
By Wisconsin Law, (ATCP 29) significant pesticide drift is considered negligent and you can be prosecuted for the results of drifts offsite. Significant pesticide drift is, readily visible, or moves to areas outside the target area and either causes actual harm or could conceivably cause harm.
Explain how pesticides can end up in animals. (Including humans)
Contaminated groundwater. Contaminated food/prey.
Biomagnification
What federal law governs pesticides and which agency oversees it?
The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)
The EPA
What is significant to remember about differing state vs federal laws?
State laws can be more strict but they cannot be more lenient than federal law. Always consult both sets of regulation when you are unsure.
Define the term “formulation”
The combination of an active ingredient with other inert ingredients.
Describe functions of active and other ingredients
Active: usually attacks target pest in some way.
“Other”: helps stabilize the formulation, helps is persist, making a.i. more potent, etc
What is an adjuvant and how is it different from “other” ingredients?
Adjuvants help certain formulations perform better, mostly in foliar applications.
Adjuvants are added by the applicator during mixing.
“Other” ingredients were added by the manufacturer as part of the formulation.
Describe “mode of action”
The mode of action of a pesticide is how or where it works against the target pest.
Growth - methoprene, pyriproxyfen
Respiration- chlorfenapyr
Nerve&Muscle - carbonates, pyrethroids, neonicotinoids
