Question 1Pest Identification, Biology, and Integrated Pest Management

Which feature best distinguishes adult insects from mites and spiders?

  1. Two body regions and eight legs
  2. Three body regions and six legs Correct answer.
  3. Four pairs of legs and wings
  4. A single body region and no legs

Explanation

Adult insects have a head, thorax, and abdomen and three pairs of legs. Mites and spiders are arachnids, with two body regions and four pairs of legs. Wings, when present, occur only on insects.

Question 2Pest Identification, Biology, and Integrated Pest Management

A pest that passes through egg, nymph, and adult stages, with nymphs resembling small adults, has which type of development?

  1. Direct development without molting
  2. Complete metamorphosis
  3. Gradual (incomplete) metamorphosis Correct answer.
  4. Asexual reproduction

Explanation

Gradual metamorphosis has three life stages: egg, nymph, and adult. Nymphs resemble adults and grow through molts without a pupal stage. Complete metamorphosis adds a distinct larval and pupal stage.

Question 3Pest Identification, Biology, and Integrated Pest Management

What does an economic threshold represent?

  1. The pest level at which control action is taken Correct answer.
  2. The pest density where control cost equals crop loss
  3. The highest pest density a crop can tolerate
  4. The number of pests caught per trap per week

Explanation

An economic threshold, or action threshold, is the pest density at which control should be started to prevent the population from reaching the economic injury level. It is usually set below the economic injury level. The economic injury level is the density at which crop loss equals control cost.

Question 4Pest Identification, Biology, and Integrated Pest Management

The main purpose of regularly scouting a field is to:

  1. Identify beneficial insects only
  2. Eliminate the need for record keeping
  3. Determine whether pest populations justify control Correct answer.
  4. Replace economic thresholds with calendar sprays

Explanation

Scouting estimates pest and beneficial insect populations and crop injury so the applicator can compare them with thresholds. It supports treatment decisions rather than replacing thresholds with calendar sprays. Good records make scouting more useful.

Question 5Pest Identification, Biology, and Integrated Pest Management

Which is an example of biological control?

  1. Applying a preemergence herbicide to the soil surface
  2. Using a trap crop around a field
  3. Releasing predatory mites to eat spider mites Correct answer.
  4. Rotating crops to break pest cycles

Explanation

Biological control uses living natural enemies, such as predators, parasitoids, or pathogens, to suppress pests. Releasing predatory mites is a direct biological control tactic. Herbicides, rotation, and trap crops are chemical or cultural tactics.

Question 6Pest Identification, Biology, and Integrated Pest Management

Crop rotation helps manage pests primarily because it:

  1. Increases the crop's tolerance to many different herbicide products
  2. Disrupts the life cycle of pests that depend on one crop Correct answer.
  3. Provides immediate control of flying insects
  4. Kills weed seeds throughout the entire soil profile

Explanation

Rotation changes the host plant available in a field, so pests specialized on the previous crop may starve or fail to reproduce. It is most effective against pests with a narrow host range and limited dispersal. Rotation does not provide immediate knockdown of mobile insects.

Question 7Pest Identification, Biology, and Integrated Pest Management

Which practice best slows the development of pesticide resistance in an insect population?

  1. Treating only after resistance appears
  2. Alternating modes of action and using nonchemical controls Correct answer.
  3. Applying sublethal doses to reduce cost
  4. Using the same mode-of-action product every season without rotation

Explanation

Resistance management relies on reducing selection pressure against a single mode of action. Rotating modes of action, using labeled rates, and integrating cultural or biological controls help susceptible individuals survive. Treating repeatedly with one product selects for resistant survivors.

Question 8Pest Identification, Biology, and Integrated Pest Management

A plant has parallel leaf veins, a fibrous root system, and hollow, jointed stems. It is most likely a:

  1. Grass Correct answer.
  2. Sedge
  3. Woody shrub
  4. Broadleaf weed

Explanation

Grasses typically have parallel veins, fibrous roots, and hollow, jointed stems. Sedges resemble grasses but usually have solid, triangular stems. Broadleaf plants have netted veins and a taproot or branched root system.

Question 9Pest Identification, Biology, and Integrated Pest Management

The three components of the plant disease triangle are:

  1. Vector, host plant, pesticide
  2. Susceptible host, virulent pathogen, favorable environment Correct answer.
  3. Infected seed, a herbicide, and high soil pH
  4. Resistant host plant, abundant beneficial insect, and very dry soil

Explanation

Plant disease develops when a susceptible host, a virulent pathogen, and a favorable environment occur together. Removing any one component can prevent or reduce disease. Resistant hosts and unfavorable environments interrupt the triangle.

Question 10Pest Identification, Biology, and Integrated Pest Management

An insect with piercing-sucking mouthparts typically causes which damage symptom?

  1. Complete removal of leaf tissue
  2. Tunnels inside stems filled with frass
  3. Chewed holes in leaves
  4. Stippling, wilting, or distorted growth Correct answer.

Explanation

Piercing-sucking insects insert mouthparts into plant tissue and remove sap. This can cause stippling, wilting, distortion, or honeydew accumulation. Chewing insects remove tissue and produce holes or tunnels.

Question 11Pest Identification, Biology, and Integrated Pest Management

Degree-day models are used in IPM mainly to:

  1. Calculate sprayer calibration rate and nozzle output
  2. Measure soil nutrient availability for crop fertility
  3. Estimate herbicide carryover in soil for the next crop
  4. Predict pest development and time scouting Correct answer.

Explanation

Degree-day models accumulate heat above a pest's developmental threshold to predict life stages. This helps time scouting and control to the most susceptible stage. They do not measure soil nutrients or sprayer output.

Question 12Pest Identification, Biology, and Integrated Pest Management

Planting a crop variety with genetic resistance to a pest is an example of:

  1. Cultural control Correct answer.
  2. Mechanical control
  3. Chemical control
  4. Biological control

Explanation

Host plant resistance is a cultural control tactic because it uses crop genetics and planting choices to reduce pest injury. It does not rely on a pesticide, a natural enemy, or a mechanical device. Resistance is most durable when used with other IPM tactics.

Question 13Pest Identification, Biology, and Integrated Pest Management

Removing and destroying diseased crop residue after harvest is an example of:

  1. Sanitation to reduce inoculum Correct answer.
  2. Biological control with predators
  3. Resistance management
  4. Chemical control with fumigants

Explanation

Sanitation removes or destroys pathogen inoculum that could survive on crop residue. Reducing overwintering inoculum can lower disease pressure the next season. It is a cultural practice rather than a pesticide or resistance tactic.

Question 14Pest Identification, Biology, and Integrated Pest Management

A new invasive insect is detected in a county for the first time. Why is early detection important for a private applicator?

  1. It allows immediate deregulation of the pest
  2. It eliminates the need for monitoring later
  3. It guarantees that the pest will never become established in the county
  4. It may permit eradication or containment before the pest spreads Correct answer.

Explanation

Early detection gives managers a chance to eradicate or contain a new invasive pest while its population is small and localized. Once an invasive species spreads widely, eradication becomes costly or impossible. Monitoring must continue after any initial response.

Question 15Pest Identification, Biology, and Integrated Pest Management

A larva that is alligator-shaped, dark with orange spots, and actively searches for aphids is likely:

  1. A Colorado potato beetle larva
  2. A corn earworm
  3. A lady beetle larva Correct answer.
  4. A cabbage looper

Explanation

Lady beetle larvae are often alligator-shaped, dark with orange or yellow markings, and are active predators of aphids and other soft-bodied insects. Recognizing them prevents unnecessary sprays that would kill beneficials. Cabbage loopers and corn earworms are caterpillars.

Question 16Pest Identification, Biology, and Integrated Pest Management

Spider mite feeding on leaves typically produces:

  1. Fine stippling and webbing Correct answer.
  2. Slimy trails on leaf surfaces
  3. Large ragged holes
  4. White, cottony masses on stems

Explanation

Spider mites have piercing-sucking mouthparts and remove cell contents, producing fine pale stippling on leaves. Heavy infestations often produce webbing. Ragged holes and slimy trails are caused by other pests.

Question 17Pest Identification, Biology, and Integrated Pest Management

Plant-parasitic nematodes are best described as:

  1. Insects that tunnel in stems
  2. Microscopic roundworms that feed on roots or aboveground parts Correct answer.
  3. Bacteria that fix nitrogen in root nodules
  4. Soil-borne fungi that cause seedling damping-off and root rot disease

Explanation

Plant-parasitic nematodes are tiny roundworms, usually living in soil and feeding on roots, though some attack aboveground plant parts. Their feeding can cause stunting, galls, or root lesions. Fungi, bacteria, and insects are separate groups of organisms.

Question 18Pest Identification, Biology, and Integrated Pest Management

Aphids are especially important in the spread of plant viruses because they:

  1. Inject fungal spores directly into the xylem vessels
  2. Lay eggs inside developing fruit so larvae feed within
  3. Chew leaf tissue and create open entry wounds for bacteria
  4. Pierce plant tissue and transmit virus while probing Correct answer.

Explanation

Aphids feed with piercing-sucking mouthparts and can acquire and transmit viruses as they probe plant tissue. Their rapid reproduction and dispersal make them efficient vectors. Virus transmission can occur quickly, even before visible aphid colonies develop.

Question 19Pest Identification, Biology, and Integrated Pest Management

Which strategy reduces the risk of fungicide resistance?

  1. Integrating cultural controls and rotating fungicide groups Correct answer.
  2. Spraying only when symptoms are severe
  3. Applying the same systemic fungicide every week all season
  4. Using lower-than-label rates to save money

Explanation

Fungicide resistance management uses labeled rates, limits the number of applications of a single mode of action, and rotates among fungicide groups. Cultural controls reduce disease pressure and the need for repeated sprays. Sublethal rates and repeated single-product use increase selection for resistance.

Question 20Pest Identification, Biology, and Integrated Pest Management

A trap crop is used in IPM to:

  1. Increase the market value of the main crop
  2. Concentrate pests away from the main crop Correct answer.
  3. Provide a harvestable early crop before the main crop is ready
  4. Supply nutrients to the main crop

Explanation

A trap crop attracts pests to a small area where they can be controlled before they move into the main crop. Its purpose is pest concentration, not crop nutrition or market value. Trap crops require monitoring and timely treatment or destruction.

Question 21Pest Identification, Biology, and Integrated Pest Management

Pheromone traps are most useful for:

  1. Monitoring adult insect activity and timing Correct answer.
  2. Measuring soil moisture
  3. Killing all insect larvae living in the soil
  4. Identifying fungal diseases on leaves and stems

Explanation

Pheromone traps attract specific adult insects and help estimate activity, emergence, and timing of scouting or treatment. They are monitoring tools, not a complete control method. They do not detect diseases or measure soil moisture.

Question 22Pest Identification, Biology, and Integrated Pest Management

Why must weed management be continued after mature weeds are removed?

  1. Weed seeds lose viability immediately when the soil is disturbed
  2. Herbicides remain active indefinitely
  3. The soil seed bank can remain viable for many years Correct answer.
  4. Weeds reproduce only by roots

Explanation

Many weed seeds survive in the soil for years and germinate after the mature plants are removed. Continued management prevents new seed production and reduces the seed bank over time. Removing only the visible plants does not eliminate dormant seeds.

Question 23Pest Identification, Biology, and Integrated Pest Management

An action threshold differs from an economic injury level (EIL) because an action threshold:

  1. Is the pest level that triggers control, usually below the EIL Correct answer.
  2. Applies only to weeds
  3. Is always higher than the EIL
  4. Is the pest density where the value of crop loss equals the cost of control

Explanation

The economic injury level is the pest density at which crop loss equals control cost. The action threshold is the lower density at which treatment is initiated to prevent the population from reaching the EIL. It applies to insects, weeds, and diseases.

Question 24Pest Identification, Biology, and Integrated Pest Management

Rotating to a nonhost crop is most effective against a plant pathogen that:

  1. Has a wide host range including many crops
  2. Survives for many years in soil as long-lived resting spores
  3. Overwinters only on crop residue or in the living host Correct answer.
  4. Is spread by wind over long distances

Explanation

Rotation works best when the pathogen depends on the crop or its residue to survive. Removing the host starves the pathogen or prevents reproduction. Long-lived soilborne spores, windborne spread, and wide host ranges reduce the effectiveness of rotation.

Question 25Pest Identification, Biology, and Integrated Pest Management

Which field practice best supports naturally occurring predators and parasitoids?

  1. Applying broad-spectrum insecticide on a calendar schedule
  2. Maintaining bare soil between rows
  3. Planting flowering borders and reducing broad-spectrum sprays Correct answer.
  4. Burning field margins each season

Explanation

Flowering borders provide nectar and pollen and refuge for beneficial insects, while reducing broad-spectrum sprays limits harm to natural enemies. This is conservation biological control. Calendar sprays, burning margins, and bare soil remove resources or directly kill beneficials.

Question 26Pest Identification, Biology, and Integrated Pest Management

An insect hatches from an egg, passes through several nymphal stages that increasingly resemble the adult, and never forms a pupa. This insect has which type of development?

  1. Paedomorphic development
  2. Incomplete metamorphosis Correct answer.
  3. Parthenogenetic development
  4. Complete metamorphosis

Explanation

In incomplete (gradual) metamorphosis the immature stages are called nymphs and look much like small versions of the adult, with no pupal stage in between. Grasshoppers, aphids, and true bugs develop this way. Complete metamorphosis, by contrast, adds a distinct pupal stage between larva and adult.

Question 27Pest Identification, Biology, and Integrated Pest Management

A seedling emerges with two seed leaves, then produces leaves with netted veins and a taproot. This plant is best classified as:

  1. A parasitic plant
  2. A broadleaf weed Correct answer.
  3. A grass weed
  4. A sedge

Explanation

Plants with two cotyledons, netted leaf venation, and a taproot are dicots, the group that includes most broadleaf weeds. Grass weeds and sedges are monocots, with a single cotyledon, parallel veins, and a fibrous root system. Identifying the seedling group early guides which selective herbicide options will work.

Question 28Pest Identification, Biology, and Integrated Pest Management

A grower examines a diseased leaf and finds white fuzzy growth and small black specks on its lower surface. In plant pathology, these visible pathogen structures are correctly termed:

  1. Symptoms
  2. Lesions
  3. Signs Correct answer.
  4. Vectors

Explanation

Signs are the physical presence of the pathogen itself, such as mycelium, spores, or bacterial ooze. Symptoms are the plant's own abnormal responses, such as yellowing, wilting, or dead tissue. Distinguishing signs from symptoms helps confirm whether the cause is infectious and which type of pathogen is involved.

Question 29Pest Identification, Biology, and Integrated Pest Management

A greenhouse grower buys and releases large numbers of commercially reared predatory mites each season to suppress thrips on a vegetable crop. This tactic is best described as:

  1. Conservation biological control
  2. Classical biological control
  3. Cultural control
  4. Augmentative biological control Correct answer.

Explanation

Augmentative biological control means releasing additional natural enemies, usually purchased, to boost the population already present during a pest outbreak. Classical control involves importing and permanently establishing a natural enemy in a new area, while conservation means protecting the enemies already there. Buying and releasing predators each season therefore fits augmentative control.

Question 30Pest Identification, Biology, and Integrated Pest Management

In a field, stunted yellowing plants appear first in low, poorly drained spots and then spread outward along drainage channels and equipment paths. Which cause best fits this pattern?

  1. A soilborne water mold spread in free water Correct answer.
  2. A seedborne bacterium carried inside seed
  3. A windblown rust fungus from distant fields
  4. A virus vectored by flying insects

Explanation

Disease that begins in wet low spots and moves along water flow and equipment is characteristic of soilborne pathogens whose swimming spores are dispersed in free water, such as water molds. Windborne rusts would appear more randomly or with prevailing winds, and vector-borne viruses typically track insect movement. The spatial pattern is the key diagnostic clue.

Question 31Pesticide Labels, Label Interpretation, and Safety Data Sheets

A pesticide label displays the signal word DANGER together with the word POISON and a skull-and-crossbones symbol. This combination indicates that the product:

  1. falls in the highest acute toxicity category for at least one route of exposure Correct answer.
  2. is a general-use product that homeowners may apply without training
  3. is regulated only because of long-term chronic health effects
  4. may be sold only to licensed pesticide dealers in the state of manufacture

Explanation

Signal words reflect the EPA acute toxicity categories assigned from oral, dermal, and inhalation studies. Category I products carry DANGER, and when the toxicity is high enough by any of those routes the word POISON and a skull-and-crossbones symbol are added. WARNING marks Category II, and CAUTION marks Categories III and IV.

Question 32Pesticide Labels, Label Interpretation, and Safety Data Sheets

Which section of a Safety Data Sheet gives the product identifier, recommended uses, and the supplier's name, address, and emergency telephone number?

  1. Section 7, Handling and Storage
  2. Section 1, Identification Correct answer.
  3. Section 9, Physical and Chemical Properties
  4. Section 2, Hazard Identification

Explanation

The 16-section SDS format opens with Identification, which names the product, states its intended use, and gives supplier and emergency contact details. This is the section an applicator uses to confirm which product the sheet describes and whom to call.

Question 33Pesticide Labels, Label Interpretation, and Safety Data Sheets

Which statement is required on the label of essentially every pesticide product registered by EPA?

  1. Do not store at temperatures below freezing.
  2. Keep out of reach of children. Correct answer.
  3. Wear a respirator during mixing and loading.
  4. Do not apply within 100 feet of any well.

Explanation

The child hazard warning is a mandatory precautionary statement that appears on the front panel of pesticide labels. The other statements are product-specific and appear only when the product's hazards or uses call for them.

Question 34Pesticide Labels, Label Interpretation, and Safety Data Sheets

Under federal law, a restricted-use pesticide may be applied by:

  1. a certified applicator, or a person under a certified applicator's direct supervision as the label allows Correct answer.
  2. any person who has carefully read the entire label
  3. only the individual who originally purchased the container
  4. any licensed commercial applicator, regardless of certification category

Explanation

Restricted-use pesticides may be used only by or under the direct supervision of a certified applicator, and the label states whether noncertified persons may work under supervision. Private applicators are certified to use restricted-use products on their own or their employer's land.

Question 35Pesticide Labels, Label Interpretation, and Safety Data Sheets

Pesticide labels must provide which item specifically for use in a poisoning emergency?

  1. The name of the EPA regional administrator
  2. The telephone number of the nearest hospital emergency room
  3. The address of the manufacturing plant
  4. A telephone number for emergency medical treatment information Correct answer.

Explanation

Labels carry an emergency telephone number, typically toll-free, that connects callers with medical treatment advice and often the manufacturer's own staff. That number, not a local hospital's, is the one printed as a label requirement.

Question 36Pesticide Labels, Label Interpretation, and Safety Data Sheets

How must an employer make safety data sheets available to workers who handle pesticides?

  1. Filed with the state pesticide regulatory agency instead of kept on site
  2. Attached to each container at the time of sale
  3. Locked in the owner's office, provided on request within 24 hours
  4. Readily accessible to workers during their work shift Correct answer.

Explanation

Hazard communication rules require that safety data sheets be kept and made readily accessible to employees while they are in their work areas. Electronic access is acceptable as long as no barriers prevent a worker from getting the information.

Question 37Pesticide Labels, Label Interpretation, and Safety Data Sheets

Which part of the label states the crops or sites where the product may be used, the application rate, and the timing of applications?

  1. Physical or Chemical Hazards
  2. Directions for Use Correct answer.
  3. Precautionary Statements
  4. Storage and Disposal

Explanation

The Directions for Use is the enforceable portion of the label that sets use sites, rates, timing, and application methods. Applying a product in a manner that conflicts with these directions is a violation of federal law.

Question 38Pesticide Labels, Label Interpretation, and Safety Data Sheets

A label statement reading 'This product is toxic to aquatic invertebrates. Do not apply directly to water' is best classified as a(n):

  1. precautionary statement about worker safety
  2. storage and disposal instruction
  3. environmental hazard statement Correct answer.
  4. physical or chemical hazard statement

Explanation

Environmental hazard statements warn of effects on wildlife, aquatic organisms, bees, or other nontarget organisms and often carry specific prohibitions. Worker safety precautions and physical hazard warnings address different risks.

Question 39Pesticide Labels, Label Interpretation, and Safety Data Sheets

The restricted-entry interval (REI) shown on a pesticide label is the period during which:

  1. the spray tank must be drained before the period ends
  2. the crop may not be harvested or consumed
  3. entry into the treated area is restricted, except for allowed tasks with required PPE Correct answer.
  4. the product may not be sold or transported

Explanation

The REI protects workers from residues that are still causing effects after an application, and it begins when the application ends. Entry is prohibited during that interval unless the label or the Worker Protection Standard permits a specific task with the required protection.

Question 40Pesticide Labels, Label Interpretation, and Safety Data Sheets

The preharvest interval (PHI) stated on a pesticide label specifies:

  1. the period treated seed may be stored before it is planted
  2. how long a worker must wait before entering a treated field
  3. the maximum number of applications allowed per growing season
  4. the minimum time between the last application and harvest of the crop Correct answer.

Explanation

The PHI is set so that residues at harvest fall within the tolerance established for that crop. Harvesting earlier than the labeled interval can leave illegal residues in the food or feed supply.

Question 41Pesticide Labels, Label Interpretation, and Safety Data Sheets

The EPA registration number printed on a pesticide label identifies:

  1. the production lot or batch the container came from
  2. the state in which the product is licensed for sale
  3. the specific product and the company that registered it Correct answer.
  4. the factory where the product was manufactured

Explanation

The registration number is assigned when EPA registers a product for a particular registrant, so it ties the container to one product and one company. The manufacturing plant is shown separately by the establishment number.

Question 42Pesticide Labels, Label Interpretation, and Safety Data Sheets

A Section 24(c) special local need registration allows:

  1. EPA to waive all label requirements during a pest outbreak
  2. a state to register an additional use of a federally registered product to address a pest problem in that state Correct answer.
  3. a dealer to relabel a product for a customer's particular crop
  4. any state to register a new active ingredient for nationwide use

Explanation

Section 24(c) lets a state issue a special local need registration for a use not on the federal label, and the resulting state label must be followed for that use. It is limited to the state that issued it and to the need described.

Question 43Pesticide Labels, Label Interpretation, and Safety Data Sheets

Which section of a Safety Data Sheet lists occupational exposure limits and engineering controls such as local exhaust ventilation?

  1. Section 5, Firefighting Measures
  2. Section 10, Stability and Reactivity
  3. Section 3, Composition/Information on Ingredients
  4. Section 8, Exposure Controls/Personal Protection Correct answer.

Explanation

Section 8 gives exposure limits, engineering controls, and the personal protective equipment recommended for the product. It is the SDS section most closely compared with the label's PPE requirements.

Question 44Pesticide Labels, Label Interpretation, and Safety Data Sheets

A grower receives a manufacturer's supplemental label for a new use of a product already registered. That supplemental label:

  1. takes effect only after it is stamped by the state chemist
  2. replaces the main label entirely once it is received
  3. is advisory only and carries no legal weight
  4. must be kept with the main label and followed for the specific use it covers Correct answer.

Explanation

A supplemental label adds or changes directions for a specific use and must be used together with the product's main label. The applicator must have the supplemental labeling in hand when making that use.

Question 45Pesticide Labels, Label Interpretation, and Safety Data Sheets

When a label permits application of a pesticide through an irrigation system, it normally requires a functional check valve or anti-siphon device in order to:

  1. prevent backflow of the pesticide mixture into the water source Correct answer.
  2. keep the pesticide from settling out in the irrigation lines
  3. increase the uniformity of the pesticide in the irrigation water
  4. measure the flow rate of water delivered to the field

Explanation

Backflow prevention keeps a pesticide mixture from being drawn into a well, stream, or public supply if system pressure drops. Without it, a chemigation run can contaminate drinking water and other off-target areas.

Question 46Pesticide Labels, Label Interpretation, and Safety Data Sheets

Under the Worker Protection Standard, when a pesticide with a label-required restricted-entry interval has been applied on an agricultural establishment, the employer must:

  1. notify workers orally or by posting the treated area, as the label and rule require Correct answer.
  2. send written notice to the nearest EPA regional office
  3. close the treated field for a minimum of 30 days
  4. issue respirators to every worker on the farm

Explanation

The WPS requires the employer to inform workers about applications and treated areas, using oral notification, posting, or both when posting is mandated. The purpose is to keep workers out of areas still under a restricted-entry interval.

Question 47Pesticide Labels, Label Interpretation, and Safety Data Sheets

Applying a registered pesticide to a use site that is not listed on its label is:

  1. a use inconsistent with the labeling and therefore a violation Correct answer.
  2. allowed whenever the product is classified as general use
  3. permitted if the application is made by a certified applicator
  4. permitted if the applicator has prior experience with the pest

Explanation

FIFRA makes it unlawful to use a registered pesticide in a manner inconsistent with its labeling. Using the product on an unlisted site is exactly that, unless a specific exemption such as a Section 18 or 24(c) authorization covers the use.

Question 48Pesticide Labels, Label Interpretation, and Safety Data Sheets

Section 2 of a Safety Data Sheet, 'Hazard(s) identification,' contains:

  1. precautions for safe handling and storage
  2. first-aid measures for each route of exposure
  3. toxicological data from animal studies
  4. the GHS classification, signal word, hazard statements, and pictograms Correct answer.

Explanation

Section 2 presents the product's hazard classification and the symbols and standardized phrases that communicate it. Signal word, hazard statements, and pictograms are all found in this section.

Question 49Pesticide Labels, Label Interpretation, and Safety Data Sheets

A product label requires chemical-resistant gloves, but the safety data sheet for the same product lists no gloves. The applicator should:

  1. wear gloves only if the product is a restricted-use pesticide
  2. ask the dealer to decide which document takes precedence
  3. wear the gloves, because label requirements must be followed Correct answer.
  4. skip the gloves, because the safety data sheet is the more technical document

Explanation

The label is the legally enforceable document, and its PPE requirements must be met regardless of what other materials say. When sources differ, the more protective requirement is the one to follow.

Question 50Pesticide Labels, Label Interpretation, and Safety Data Sheets

Which statement best describes the storage instructions printed on a pesticide label?

  1. They are enforceable label directions, and storing the product contrary to them can be a violation Correct answer.
  2. They apply only during the growing season
  3. They apply only to products classified as restricted use
  4. They are suggestions for best practice and carry no legal force

Explanation

Storage and disposal statements are part of the labeling, and failing to follow them can be a misuse of the product. They also protect the product's integrity and prevent accidental exposure or environmental contamination.
