IDA General Standards Exam Flashcards
How do you calculate the area of a circle?
3.14rr
To which class do Mites belong?
Class Arachnida, subclass Acari
What is IPM?
Integrated Pest Management
Which plant disease is transmitted through air?
Fungi
Incomplete (or simple) metamorphosis
3 life stages: Egg > Nymph > Adult
Complete metamorphosis
4 lifes stages: Egg > Larva > Pupa > Adult
Broadleaf weed characteristics
Larger, open (broad) surface with network of veins
Annual weeds
Complete their life cycle within one year
Biennial weeds
Complete half the life cycle in year one, the second half in year two
Perennial weeds
Live for more than two years
Herbaceous Perennials
Stems die back to the ground each winter
What is an adjuvant?
Adjuvants modify the chemical properties to enhance performance (they include drift reduction, surfactants, stickers, penetrants, etc.)
What is an emulsifiable concentrate?
ECs have one liquid suspended as tiny droplets inside another liquid
Why do a small jar mixing test?
To ensure components are physically compatible
Systemic pesticides
Move within the plant
Contact pesticides
Kill what it touches on the surface
How do pests build resistance?
A select few that survive due to their genetic makeup pass on their resistant genes to their offspring
How do you prevent pest resistance?
Use pesticides with different modes of action
What does every label contain?
Product information, precautionary statements, directions for use
Signal words
DWC: Danger (high toxicity), Warning (moderate toxicity), and Caution (low to very low toxicity)
LD50
Lethal Dose 50; the amount of pesticide required to kill 50% of the test population
How is the LD50 expressed?
In milligrams of pesticide per kilogram of animal body weight (mg/kg)
How to treat pesticides in the eye?
Hold open and rinse with clean water for 15 minutes
What should you do with excess product?
Use as directed by the label, never pour it down a drain, if necessary have it incinerated or brought to special landfills
Why is acute oil-based pesticide poisoning so toxic?
Oils travel through the skin quickly and bring the pesticide with it
What is PPE?
Personal protective equipment. Ranges from simple (long sleeve shirt, pants, socks, shoes, hat, gloves) to extreme (apron, rubber boots, respirator, face shield)
How often should you wash your uniform?
Daily
How do you clean a spray nozzle?
With a nozzle brush. Don’t use a knife or wire, it can damage it
What is optimal application?
Even application
How to reduce drift?
Lower the spray height, increase droplet size, spray on days with less wind, cooler temperatures, and more humidity
What is vapor drift?
When pesticides move through air and off target (escape the desired area)
Best soil type to contain runoff
Soil with high clay, silt, and organic matter content
Worst soil type to contain runoff
Sandy soil
What is a chemical half life?
How long it takes for one half of the pesticide to break down in soil
Who do you contact if a spill occurs?
The manufacturer can decide if it should escalate to IEMA, CERCLA, or SARA. CHEMTREC can help with poison control
Who records spills?
National Response Center
How to treat for spills?
CCC = Control (Stop the leak), Contain (use absorbent material to keep it from spreading further), Clean up (remove the spill)
How far can bees fly?
3 miles
What formulation is most toxic to bees?
Microencapsulated; it can travel back to the hive and kill the entire colony
Woody Perennials
have persistent aboveground stems that remain over winter
Cultural control
Changing regular practices (Mowing more frequently, cleaning, taking out the trash)
Mechanical control
Using devices (snap traps, aeration)
Which label is on the exam?
I don’t know, remember it from the exam
Biological control
Predators, parasites (fish that eat mosquito larva in ponds)
Preventative control
Quarantines, inspecting imported goods (you can’t bring fruit back from Hawaii in order to keep their pests from spreading here)
Chemical control
Herbicides, insecticides, fungicides (spraying)
Noninfectious plant diseases
Caused by unfavorable growing conditions like extreme heat or moisture, soil compaction, excess pesticide
Infectious plant diseases
Caused by pathogens such as bacteria, fungi, viruses, nematodes
Buffering agents
Adjuvants used to counteract the negative effects of PH that could otherwise render the active ingredients uselewss
Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)
Federal framework stating that if used according to the label, pesticides will add some pest relief. FIFRA is administered by the US Environmental Protection Agency (USEPA)
Federal Environmental Pesticide Control Act (FEPCA)
An amendment to FIFRA making the label a legal document, regulation a federal duty, products used in the US to be approved by the USEPA, classifying products as general use or restricted use
Occupation Safety And Health Administration (OSHA)
Keeps workers safe. Enforces that employees know of the pesticides/chemicals in their workplace and that Material Safety Data Sheets (MSDS) are available
