ID Core | Applicator Training

Question 1

The key to minimizing the hazard of pesticide use to the applicator is to avoid exposure.

Answer 1

True. Avoid exposure!

Question 2

Physical Control methods kill pests, disrupt their life cycle, or make the environment unfavorable. An example would be changing the temperature in a room.

Answer 2

True. Examples of physical control:
- Heat treatment for bed bugs
- Putting lights in the attic to keep bats from nesting there

Question 3

Cultural Control disrupts the relationship between a pest and it’s host through routine management practices.

Answer 3

True. Examples of cultural control:
- Pruning plants
- Varying the time you plant crops

Question 4

Genetic Control involves the use of parasites or predators to a pest.

Answer 4

False. Genetic Control involves creating or introducing animals and plants resistant to attack. Examples:
- GMO crops (Genetically modified organisms) that won’t be eaten by insects
- Sterilizing male flies and introducing them back into the population to mate with females who will later lay sterile eggs, meaning the fly population goes down

Question 5

Biological Control involves the introduction or increase of parasites or predators to a pest.

Answer 5

True. Examples include:
- Introducing more wasps to eat an invasive beetle species that was harming crops
- Introducing a parasite to eat the eggs of an invasive species of fly, reducing the population

Question 6

Mechanical Control means building a machine to kill pests.

Answer 6

False. Mechanical Control means using screens, nets and fences to destroy pests or keep them out. Examples:
- Putting a screen over your attic vent to keep rats out
- Building a fence to keep deer away from a garden
- Putting a mesh bag over apples tree branches to keep insects off the fruit

Question 7

Legal Control means preventing people from becoming pesticide applicators if they have a criminal history.

Answer 7

False. Legal Control means making rules to control human activities. Example:
- Setting up quarantine zones to prevent the spread of pests

Question 8

Chemical Control involves using pesticides to kill, attract, repel, or change pests.

Answer 8

True. Examples include:
- Rodenticides to kill rodents
- Herbicides to kill weeds
- Insecticides to kill insects
- And many more!

Question 9

Pesticide drift can be reduced by spraying upwind from a sensitive area.

Answer 9

False. Reduce drift by spraying large droplets of product. Avoid fine mists that float along the breeze.

Question 10

Emulsifiable concentrates need constant agitation.

Answer 10

False. These milky white liquids mix well with water, are easy to transport, and don’t clog sprayers. They don’t need to be shaken to stay emulsified. They’re easy!

Question 11

Emulsifiable concentrates are very concentrated oil-based products, meaning you only need a small amount of product mixed into your sprayer.

Answer 11

True. Because they’re so concentrated…
- You don’t have much margin for error when mixing
- They’re easily absorbed into human skin
- They’re flammable
- They can damage painted surfaces and cause corrosion

Question 12

Soluable powders and wettable powders both dissolve in water

Answer 12

False.

Soluable powders DO dissolve in water. Imagine stirring sugar into hot coffee until the sugar dissolves.

Wettable powders DON’T dissolve in water. Your tank must be agitated constantly to prevent settling. They tend to clog sprayers. Imagine stirring flour into your coffee and it clumping on the bottom of your cup.

Question 13

Flowables are very similar to wettable powders

Answer 13

True. Flowables are wettable powders that have been engineered to flow better in water and with less clogging and less stirring.

Question 14

Water dispersible granules are sand-like versions of wettable powders.

Answer 14

True. They aren’t as dusty since the particles are bigger.

Question 15

Most pesticide dusts require mixing with a clay powder in the field before application.

Answer 15

False. Pesticide dusts come ready to use out of the package, usually with the active ingredient contained within clay or talcum powder.

Question 16

A disadvantage of dust pesticide is that it drifts around easily

Answer 16

True. It blows around a lot!

Question 17

Water dispersible granules and Granular pesticides are the same thing.

Answer 17

False. A Water dispersible granule must be mixed with water and sprayed on. Granular pesticides are ready to go out of the package and usually just spread on the ground.

Question 18

Baits can be dangerous to kids and pests because they contain attractants and edible substances.

Answer 18

True

Question 19

Baits can be ineffective if there are other food sources nearby for the pest.

Answer 19

True

Question 20

Ultra-low volume applications are safer than high volume applications.

Answer 20

False. Ultra-low volume sprays use very little water, meaning you’re spraying a very small amount of product. This means that the product is VERY concentrated and therefore more dangerous if it comes into contact with human skin or drifts to a non target area.

Question 21

Microencapsulated pesticides have active ingredient encapsulated in a tiny capsule which slowly releases the active ingredient over time.

Answer 21

True. They last a really long time and the re-entry interval is longer for applicators. They pose a special risk to pollinators since a bee can carry the product back to the hive by accident when collecting pollen.

Question 22

Bug bombs and mosquito foggers are examples of aerosol pesticides.

Answer 22

True.

Question 23

It can be difficult to get good coverage with an aerosol pesticide.

Answer 23

False. The small droplets in a spray can or fogger spread small droplets easily and evenly, providing great coverage.

Cons to aerosols are:
- Easy to accidentally inhale product
- Tough to contain the product to the target area

Question 24

All pesticide applicators in the State of Idaho can apply fumigants.

Answer 24

False. Fumigants are the most hazardous form of pesticides the EPA has placed special regulations on who can purchase and apply these products.

Question 25

Flea collars are a common example of a Pesticide impregnated material.

Answer 25

True. A plastic or rubber material is impregnated with pesticide and slowly released to the animal wearing the collar or ear tag.

Question 26

The WALE method of pesticide mixing helps you remember the order for adding products into your tank. Start with a half a tank of water, then add... 1. Wettable powders and granules 2. Agitate to mix 3. Liquid pesticides 4. Emulsifiable concentrates ...Top off with water

Answer 26

True. Note that the W in WALE doesn't stand for "water" despite it being the first step which is very confusing!

Question 27

Having a mixture of pesticides clump, create globules, or separate into layers are all examples of a compatible mixture.

Answer 27

False. Clumps, globules, or separating into layers are all examples of INcompatible pesticide mixtures.

Question 28

When a pesticide mixture looks incompatible (globules, clumps, separation of layers) it can lose effectiveness and increase hazards to people and animals.

Answer 28

True.

Question 29

If you're mixing two pesticides together for the first time you should perform a small mixing test in a clear jar before making a large batch in your tank.

Answer 29

True. Use the WALE method to ensure you add products in the right order.

Question 30

An adjuvant is a product added to rodenticide to make it taste better to rats.

Answer 30

False. An adjuvant is an additive that modifies a pesticide's physical properties to enhance performance. They're most commonly used on foliage to get the pesticide product to stick properly on the leaves.

Question 31

Surfactants, stickers, penetrants, thickening agents, and safeners are all examples of adjuvants.

Answer 31

True. For example a thickening might be added to a crop spray to reduce drift.

Question 32

The EPA and ISDA (Idaho State Department of Agriculture) are the only agencies that regulate pesticides.

Answer 32

False.

Question 33

All formulations with the same active ingredient carry the same signal word.

Answer 33

False. Some formulations are more hazardous than others. For example a fumigant is much more hazardous than a granule.

Question 34

The safest way to dispose of a pesticide is to rinse it down the drain.

Answer 34

False. Follow the label instructions. The label is the law!

Question 35

Every pesticide must include a signal word.

Answer 35

True. - ☠️ DANGER POISON with a skull and crossbones = Highly toxic - WARNING = Moderately toxic - CAUTION = Slightly toxic

Question 36

An EPA registration number is only required for pesticides that carry the skull and crossbones symbol and the signal word DANGER POISON

Answer 36

False. All pesticides have an EPA registration number on the label.

Question 37

The following are examples of "Precautionary Statements" found on a pesticide label: - Route of Entry (mouth, skin, lungs) - Specific Action (do not get in eyes, avoid breathing dust) - Protective Clothing (wear tightly fitted goggles when applying overhead)

Answer 37

True. There are three main types of precautionary statements found on labels. You might find all three types or none at all depending on the product. - Route of Entry - Specific Action - Protective Clothing

Question 38

A pesticide label has a Route of Entry statement that reads "Fatal if swallowed. Corrosive severe skin burns." You would expect this label to have the signal word "CAUTION."

Answer 38

False. The signal word would be DANGER POISON ☠️ because it is potentially fatal. The word CAUTION indicates a product is only slightly toxic.

Question 39

You've ingested a pesticide. The poison control hotline is the only resource for getting information on the right type of medical care.

Answer 39

False. The label contains a section called "Practical Treatments" that outlines medical care for poisoning emergencies. Physicians and field staff can refer to this section for help.

Question 40

General environmental statements appear on most pesticide labels. They are common sense instructions like "do not contaminate water" and "do not apply when bees are in the area."

Answer 40

True. Preventing water pollution, limiting drift, and protecting pollinators are all common sense instructions on almost every pesticide label.

Question 41

The re-entry interval (REI) tells you how much time must pass before people can reenter a treated area without wearing PPE.

Answer 41

True.

Question 42

If a pesticide label doesn't state a re-entry interval, people can walk through a pesticide application immediately.

Answer 42

False. Always wait until sprays have dried and dusts have settled.

Question 43

To dispose of a pesticide container legally, you must read the label and follow local laws.

Answer 43

True.

Question 44

Killing an endangered species with a pesticide is illegal under the Endangered Species Act.

Answer 44

True.

Question 45

The following are all examples of product restrictions: - Cannot be applied to sandy soil - Must be applied with a specific type of sprayer - Cannot be applied in freezing temperatures

Answer 45

True.

Question 46

The "Directions for Use" section of a label is the longest portion of the label and provides extensive instructions on: - Type of pests you can treat - How much product to use - Where and when you can use the product - Equipment for applying product - And much more!

Answer 46

True.

Question 47

It's legal to apply a product for a non-target pest if the site or plant you're applying it to is listed on the label.

Answer 47

True. If a product is labeled for aphid control on apples trees, you can generally use it for ant control on apple trees (even if ants are not specifically mentioned on the label).

Question 48

The pre-harvest interval is a suggestion made by a pesticide manufacturer.

Answer 48

False. The EPA sets pre-harvest intervals to make sure a pesticide has broken down to safe levels before food is harvested and eaten by people.

Question 49

A pesticide label is a legal document.

Answer 49

True. The label is the law!

Question 50

Regardless of the signal word they bear, all pesticide labels must carry the words "KEEP OUT OF REACH OF CHILDREN"

Answer 50

True.

Question 51

Labels should be removed from pesticide containers and kept in a notebook so they remain clean and legible.

Answer 51

False! Never remove a pesticide label. Keep copies in your safety binder.

Question 52

An active ingredient often has many names: - The chemical compound's technical name (1-naphthyl N-nethyl cabamate) - A common name (Carbaryl) - Product or brand names that contain that ingredient (Sevin 50WP Insect Killer)

Answer 52

True. Know the difference between a technical name, a common name, and a product name.

Question 53

Pesticide residue is counted in PPM (parts per million)

Answer 53

True

Question 54

The EPA writes pesticide labels.

Answer 54

False. The company producing the pesticide writes the label and the EPA reviews it.

Question 55

Inert ingredients are carriers for the active ingredient. For example an insecticide dust may contain .5% active ingredient and 99.5% clay dust.

Answer 55

True.

Question 56

A General Use Pesticide can be sold to the general public because it does not pose a large risk to the public.

Answer 56

True. General Use Pesticides are widely available to everyone. A Restricted Use Pesticide has a high potential to harm the public and can only be sold to people with a pesticide license.

Question 57

The ISDA has the right to classify a pesticide as "Restricted Use" in the State of Idaho even if the EPA has classified it as a "General Use."

Answer 57

True.

Question 58

A certain active ingredient has a chemical compound name and one accepted common chemical name, but may be in products with several different trade/brand names.

Answer 58

True.

Question 59

If you notice a pesticide bottle is missing it's label you should store the damaged bottle with a new bottle with the same label to avoid confusion.

Answer 59

False. Order a replacement label from the manufacturer.

Question 60

There are six major components to IPM (integrated pest management) 1. Pest identification 2. Monitoring pest numbers and damage 3. Guidelines for when management is needed 4. Prevention 5. Combining biological/cultural/physical/mechanical and chemical control 6. Assessing your results

Answer 60

True.

Question 61

Pest monitoring should be done along field borders, doorways and other natural boundaries where pests hide.

Answer 61

False. Monitoring should be random to make sure you get a good idea of pest populations.

Question 62

Pest monitoring can be impacted by temperature. The "degree-day" or "heat unit" approach will help you choose the right time of year or time of day for monitoring.

Answer 62

True. Monitoring for ant activity in January will give very different results compared to July.

Question 63

The Economic Injury Level or Economic Threshold helps you compare the cost of pest damage to the cost of pest control. When you reach that level it makes sense to control the pest vs doing nothing.

Answer 63

True. For example, losing 1% of your crop to insects may be acceptable but losing 10% of your crop may be more expensive than hiring a pest control applicator to spray your field. You've reached the Economic Threshold to take action.

Question 64

The Aesthetic Injury Level or Aesthetic Threshold for each pest can be looked up in a table on the ISDA website.

Answer 64

False. Aesthetic Injury is very subjective and based on the whims of the customer. A lady who sees one ant in her kitchen may want the entire house fumigated. As a pesticide applicator we must educate customers and use IPM best practices to prevent over-applying pesticides.

Question 65

One of the earliest uses of chemicals as a pesticide was the burning of sulfur.

Answer 65

True.

Question 66

Cultivation and pruning plants are considered natural pest control methods.

Answer 66

False. Rain, wind, sunshine, heat and other naturally occurring changes in climate are considered natural pest control. Example: Every winter wasps are no longer a problem due to the cold.

Question 67

All pesticides kill only the target pests.

Answer 67

False.

Question 68

The goal of all pest management programs is to eradicate the pest.

Answer 68

False.

Question 69

Fertilizer is considered a pesticide in the State of Idaho.

Answer 69

False.

Question 70

A systemic pesticide is absorbed into the plant and moved around through the root and leaves. This process is known as translocation.

Answer 70

True. Systemic insecticides provide coverage on the entire plant, not just the leaves it's applied to.

Question 71

DDT, a World War II pesticide that was incredibly effective, was banned because it did not break down quickly. It was persistent and built up in animals.

Answer 71

True.

Question 72

Piscicides control spiders.

True.

Question 75

Organophosphates, carbamates, and chlorinated hydrocarbons and pyrethriods are all synthetic organic insecticides.

Answer 75

True.

Question 76

Acaricides control rodents.

Answer 76

False. Acaricides control mites and spiders.

Question 77

Phytotoxic chemicals are toxic to plants.

Answer 77

True. Herbicides are a type of phytotoxic chemical. The products prevent the plant from photosynthesis and the plant dies.

Question 78

Fungicides are more effective in large, active fungus colonies.

Answer 78

False. Fungicides are best for young plants and preventing fungus.

Question 79

Nematicides are usually fumigants. They control nematodes.

Answer 79

True.

Question 80

There are two main types of rodenticide; anticoagulants and acute compounds.

Answer 80

True. Anticoagulants typically take longer to work and require several feedings. Acute compounds work for fast knockdown but are more toxic and dangerous.

Question 81

Growth regulators, defoliants and desiccants are not pesticides but they are regulated as pesticides in the State of Idaho.

Answer 81

True.

Question 82

Wood preservatives/pressure-treated wood are generally considered safe for use as firewood.

Answer 82

False. Wood preservatives/pressure-treated wood are resistant to fungus and insects. The treatment makes them unsafe to burn. Wear PPE when sawing it.

Question 83

Synthetic organic insecticides include chlorinated hydrocarbons.

Answer 83

True.

Question 84

The four routes of pesticide exposure are: 1. Skin (dermal) 2. Lungs (inhalation) 3. Mouth (oral) 4. Genital transfer

Answer 84

False. The four ways pesticides enter the body are: 1. Skin (dermal) 2. Lungs (inhalation) 3. Mouth (oral) 4. Eyes Your scrotum and your head absorb pesticide easily. But it's a type of skin exposure.

Question 85

Lung inhalation is the most common route of entry for pesticide poisonings.

Answer 85

False. Skin absorption is about 97% of all exposures.

Question 86

It takes an average of 3 exposures to an acutely toxic product to have a harmful effect.

Answer 86

False. Products are considered acutely toxic if they are harmful with just one exposure.

Question 87

A product with an LD50 of 2 MG/KG is more toxic than a product with an LD50 of 10 KG/MG.

Answer 87

True. The LOWER the number, the HIGHER the toxicity. This is because it takes a small amount to be toxic.

Question 88

It's best to scrub your skin vigorously if it's been exposed to a pesticide.

Answer 88

False. Gently rinse your skin and follow label instructions.

Question 89

If a person ingests a pesticide you should induce vomiting immediately

Answer 89

False. Read the label. Vomiting is often non recommended.

Question 90

Organophosphates are responsible for most pesticide poisonings.

Answer 90

True. It impacts the nervous system: - Headache/dizziness - Trouble breathing - Nausea - Pale/sweating - Pupils that don't respond to light

Question 91

If you regularly work with organophosphates you can have your blood tested regularly to monitor your "Cholinesterase" exposure levels.

Answer 91

True. Blood tests look for Cholinesterase.

Question 92

There are antidotes for organophosphate exposure.

Answer 92

True

Question 93

Toxic and hazardous are synonyms.

Answer 93

False. Toxicity = The potential to cause harm. Is this product poisonous? Hazard = The likelihood to cause harm. How is it applied?

Question 94

Because of the protective nature of eye tissues, very little pesticide that contacts the eyes is actually absorbed.

Answer 94

False. Eyes absorb a lot of pesticide.

Question 95

Symptoms of pesticide poisoning always occur immediately after exposure

Answer 95

False. Symptoms may be immediate or delayed.

Question 96

Chronic toxicity from a pesticide is from small, repeated exposure over time.

Answer 96

Question 104

Pesticide-contaminated clothing should be washed separately from the family laundry in hot water with laundry detergent.

Answer 104

True. Do not use bleach!

Question 105

Backsiphoning occurs when a pesticide mixture in a tank is sucked back up the water hose. Prevent this by using an anti-backflow device, keeping the hose above the water level in the tank, and watching closely as you fill.

Answer 105

True.

Question 106

Waste rinse water from mixing pesticides is called "rinsate." It can be disposed of in two ways: 1. Add it to the tank for a future pesticide application 2. Diluting it down with more water and spraying it over the current treatment area

Answer 106

True

Question 107

It's best to mix large amounts of pesticide at once so you don't have to mix them as often.

Answer 107

False. Only mix the amount you need.

Question 108

A closed handling system allows the applicator to open a pesticide container, rinse it, and transfer the pesticide and rinsewater to the spray tank without contacting the pesticide.

Answer 108

True. They can greatly reduce exposure to pesticides

Question 109

Pesticide storage requires a 6ft fence and highly visible warning signs. No smoking signs should be posted.

Answer 109

True.

Question 110

If a nozzle becomes clogged while spraying you should move to an untreated area and use a soft brush to clean the nozzle.

Answer 110

True.

Question 111

A well lighted storage area with lots of direct sun is best for pesticide storage

Answer 111

False. Keep pesticides out of direct light.

Question 112

Shipping unused pesticides to the EPA is the best way to dispose of unwanted products.

Answer 112

False. Use it in a way consistent with the label. If you can't use it, give it back to the distributor or find another applicator in your area who needs it.

Question 113

Triple rinsing is the best way to clean an empty pesticide container. Always collect the rinsewater

Answer 113

True.

Question 114

Hosing pesticides down a storm drain is the best way to clean up a spill.

Question 115

Application records should be kept for no less than 2 years

Answer 115

True

Question 116

To control a pesticide spill: 1. Keep people at least 30 ft away 2. Call the Idaho emergency response commission 3. Use a shovel or rake to make a dam out of dirt and stop the flow and protect water sources! 4. Absorb the spill with a spill kit 5. Clean your equipment and clothing

Answer 116

True

Question 117

Wind speed of 10 mph or more are likely to cause drift

Answer 117

True

Question 118

The riskiest time of day for pesticide drift is noon, when the sun is hottest and creates a temperature inversion.

Answer 118

False. Temperature inversion happens in early evening or early morning because air at ground level is cooler than the air up high. This temperature difference creates a lot of air movement and the potential for drift.

Question 119

Volitization is when a pesticide turns into a gas. Hot weather makes volitization more likely.

Answer 119

True.

Question 120

Adsorption and Absorption are the same thing

Answer 120

False. Adsorption: When a pesticide molecule binds to soil. Absorption: When a plant sucks up a pesticide.

Question 121

Adsorption is most common in soil that's full of clay and compost.

Answer 121

True. Clay-like soil sucks up pesticides. Coarse, sandy soil does not adsorb as much.

Question 122

The risk of pesticide runoff is highest if an application is done right before it rains.

Answer 122

True.

Question 123

Leaching and runoff are both common ways for pesticides to enter waterways.

Answer 123

True. - Runoff: When a pesticide rolls on the top of the soil - Leaching: When a pesticide sucks down through the soil

Question 124

Pesticide leaching is common in clay-like soil.

Answer 124

False. Clay-like soil adsorbs pesticides. It sucks the pesticide in and doesn't allow it to move through the soil into the water below. Leaching is more common in coarse, sandy soil.

Question 125

Microbial degredation is when fungi and bacteria eat the pesticide

Answer 125

True

Question 126

Chemical degredation is when a pesticide breaks down over time

Answer 126

True

Question 127

Photodegredation is when a pesticide breaks down the plant it was applied to.

Answer 127

False. Photodegredation is when the pesticide itself breaks down in sunlight and becomes less effective

Question 128

Runoff is usually more likely from a water-saturated soil than from an unsaturated soil.

Answer 128

True. The soil can't adsorb any more water and the pesticide just rolls right over it and spreads.

Question 129

The water table sits above ground and is visible to the naked eye.

Answer 129

False. The water table is the upper-level of the water zone that's underground. We access it via wells. The water we see in rivers, lakes, and streams is called surface water.

Question 130

It is very difficult to clean/purify ground water that is contaminated with pesticides

Answer 130

True

Question 131

Leaching is the main way pesticides reach ground water

Answer 131

True

Question 132

Pesticide properties have little if any effect on whether a chemical will reach groundwater.

Answer 132

False

Question 133

Dust formulations are the safest type of product for bees.

Answer 133

False. Avoid dusts to keep pollinators safe.

Question 134

Fish kills most commonly result from pollution of water by insecticides.

Answer 134

True

Question 135

Drift can be reduced by spraying downwind of a sensitive area and leaving an untreated border

Answer 135

True

Question 136

Agricultural sprays that have the potential to harm bees should be done at midday.

Answer 136

False. During the times crops and/or weeds are in bloom, pesticide applications that are toxic to bees may only be made from three hours before sunset until three hours after sunrise

Question 137

Directed-spray maximizes coverage of the target organism and minimizes coverage to the protected plant or animal.

Answer 137

True

Question 138

Foliar applications are those applications that spray solutions are injected into the ground and are trans located to the foliage

Answer 138

False

Question 139

Cut stump treatments are injections of pesticides made directly into a tree

Answer 139

False. Cut-stump treatments are applied immediately after the tree is cut down

Question 140

A stopwatch is needed to properly calibrate the delivery rate of a large spray rig.

Answer 140

True. You should also use flags to mark out the area and have accurate measuring devices. You will likely need a calculator.

Question 141

The two most important variables in sprayer output are: - Nozzle flow rate - Ground speed of the sprayer

Answer 141

True

Question 142

Doubling the sprayer's pressure will double the flow rate

Answer 142

False. Changing nozzle tips will change the flow rate.

Question 143

Band treatments usually require less actual pesticide applied per acre when compared to broadcast treatments.

Answer 143

True

Question 144

Chemigation is the application of fertilizer or pesticide through sprinklers, gravity drip irrigation, or well irrigation systems.

Answer 144

True.

Question 145

Early season weed control is a great use case for a low-pressure hydraulic sprayer

Answer 145

True

Question 146

A high-pressure hydraulic sprayer is great for spot applications (not broad applications)

Answer 146

True

Question 147

An air-blast sprayer would work well for a fungicide treatment on a fruit orchard.

Answer 147

True

Question 148

It is always a good idea to operate a pump dry for a few minutes to completely drain any liquid out of the sprayer system.

Answer 148

False

Question 149

Plastic nozzles can be dissolved easily and should not be used with solvents. Use brass or ceramic instead

Answer 149

True
