Question 1Pesticide Laws, Regulations, and Certification Requirements

Which federal statute is the primary law governing pesticide registration, labeling, and use in the United States?

  1. OSHA
  2. ESA
  3. CWA
  4. FIFRA Correct answer.

Explanation

FIFRA is the Federal Insecticide, Fungicide, and Rodenticide Act, which establishes EPA registration and labeling requirements for pesticides. The other statutes address water pollution, endangered species, and workplace safety rather than pesticide registration as their primary focus.

Question 2Pesticide Laws, Regulations, and Certification Requirements

Under FIFRA, applying a registered pesticide in a manner inconsistent with its labeling is best described as:

  1. Unlawful and subject to enforcement Correct answer.
  2. Legal when the application is made by a commercial applicator
  3. Allowed if the crop is not listed on the label
  4. Permitted when the applicator is certified

Explanation

The pesticide label is enforceable under FIFRA, and use inconsistent with the label is unlawful. Certification or commercial status does not authorize off-label use.

Question 3Pesticide Laws, Regulations, and Certification Requirements

Which South Dakota agency is the lead state agency responsible for pesticide applicator certification and pesticide enforcement?

  1. Department of Health
  2. Department of Game, Fish and Parks
  3. Department of Agriculture and Natural Resources Correct answer.
  4. Department of Transportation

Explanation

The South Dakota Department of Agriculture and Natural Resources administers the state pesticide program, including applicator certification and enforcement. The other agencies have different missions such as wildlife, public health, and highways.

Question 4Pesticide Laws, Regulations, and Certification Requirements

Under FIFRA, a private applicator is a certified applicator who uses or supervises the use of restricted use pesticides:

  1. On owned or rented agricultural land Correct answer.
  2. Only inside warehouses and food plants
  3. Only on government-owned property
  4. For hire on any customer property

Explanation

A private applicator applies restricted use pesticides on land owned or rented by the applicator or employer to produce an agricultural commodity, generally without compensation. Applications for hire on others' property are commercial, and government employees are public applicators.

Question 5Pesticide Laws, Regulations, and Certification Requirements

A person who applies restricted use pesticides for compensation on property owned by others is classified as a:

  1. Private applicator
  2. Commercial applicator Correct answer.
  3. Dealer
  4. Noncertified handler

Explanation

A commercial applicator uses restricted use pesticides for compensation or on property other than the private applicator's own or rented agricultural land. A private applicator works on owned or rented agricultural land, while a dealer sells pesticides.

Question 6Pesticide Laws, Regulations, and Certification Requirements

A city parks department employee who applies restricted use pesticides as part of her job is best classified as a:

  1. Certified dealer
  2. Private applicator
  3. Commercial applicator
  4. Public applicator Correct answer.

Explanation

A public applicator is a government employee who applies restricted use pesticides as part of official duties. Commercial applicators apply for compensation in the private sector, and private applicators apply on their own or rented agricultural land.

Question 7Pesticide Laws, Regulations, and Certification Requirements

An uncertified farm employee may apply a restricted use pesticide only when:

  1. Under direct supervision of a certified applicator Correct answer.
  2. The pesticide is mixed at half the labeled rate
  3. The employee has read the label
  4. The application occurs on a weekend

Explanation

Restricted use pesticides may be applied by a certified applicator or by a noncertified person working under the direct supervision of a certified applicator. Reading a label or reducing the rate does not substitute for certification and supervision.

Question 8Pesticide Laws, Regulations, and Certification Requirements

How long must a certified applicator keep records of restricted use pesticide applications under federal regulations?

  1. 2 years Correct answer.
  2. 1 year
  3. 6 months
  4. 5 years

Explanation

Federal regulations require certified applicators to keep records of restricted use pesticide applications for two years. Shorter periods would not meet the requirement, and five years exceeds the federal minimum.

Question 9Pesticide Laws, Regulations, and Certification Requirements

When a commercial applicator applies a restricted use pesticide for a customer, the applicator must:

  1. Discard the record after the application is complete
  2. Keep the record confidential from the customer
  3. Send the record only to EPA headquarters
  4. Give the customer a copy of the record Correct answer.

Explanation

Commercial applicators must provide the customer with a copy of the restricted use pesticide application record while also retaining their own records. Records are not sent only to EPA and cannot be discarded immediately.

Question 10Pesticide Laws, Regulations, and Certification Requirements

Dealers who sell restricted use pesticides must keep records of those sales for at least:

  1. 30 days
  2. 2 years Correct answer.
  3. 10 years
  4. 6 months

Explanation

Federal rules require restricted use pesticide dealers to keep sales records for two years. The other periods are either too short or longer than the federal requirement.

Question 11Pesticide Laws, Regulations, and Certification Requirements

Which statement best describes when pesticide applicator certification is required in South Dakota?

  1. It is required to apply restricted use pesticides Correct answer.
  2. It is required for all pesticide applications, including general use products
  3. It is required only when applying on public land
  4. It is required only for aerial applications

Explanation

Certification is required for applying restricted use pesticides, which are classified for use only by certified applicators or persons under their supervision. General use products do not require certification, although other rules may still apply.

Question 12Pesticide Laws, Regulations, and Certification Requirements

If a pesticide label and a state regulation both address the same application practice, the applicator must generally:

  1. Choose whichever requirement is easier to meet
  2. Comply with both, following the more restrictive requirement Correct answer.
  3. Follow only the label and ignore state rules
  4. Follow only the state rule and ignore the label

Explanation

A state may impose additional restrictions on pesticide use, but it cannot permit use inconsistent with the federal label. When both apply, the applicator must satisfy both, which means following the more restrictive requirement.

Question 13Pesticide Laws, Regulations, and Certification Requirements

A pesticide is considered misbranded when its label:

  1. Lists the active ingredient
  2. Includes the EPA registration number
  3. Shows a restricted use classification
  4. Contains false or misleading statements Correct answer.

Explanation

Misbranding includes false or misleading label statements and omission of required information. Including the registration number, active ingredient, and restricted use classification are required or permitted label elements, not misbranding.

Question 14Pesticide Laws, Regulations, and Certification Requirements

Which mechanism allows EPA to authorize temporary use of an unregistered pesticide during a public health emergency?

  1. Emergency exemption under section 18 Correct answer.
  2. Experimental use permit under section 5
  3. Minimum risk exemption under section 25(b)
  4. Special local need registration under section 24(c)

Explanation

Section 18 of FIFRA provides emergency exemptions for unregistered uses when an emergency pest situation exists. Section 24(c) addresses special local needs, section 5 covers experimental testing, and section 25(b) covers minimum risk products.

Question 15Pesticide Laws, Regulations, and Certification Requirements

A state registration for a pesticide to meet a special local need not addressed by the federal label is authorized under:

  1. Section 18
  2. Section 24(c) Correct answer.
  3. Section 5
  4. Section 25(b)

Explanation

Section 24(c) of FIFRA allows states to register additional uses for a federally registered pesticide to meet a special local need. Section 18 is for emergencies, section 5 for experimental use, and section 25(b) for minimum risk products.

Question 16Pesticide Laws, Regulations, and Certification Requirements

An experimental use permit is required when a pesticide is applied:

  1. Under an emergency exemption
  2. According to its registered label
  3. Under a special local need label
  4. For field testing to support registration Correct answer.

Explanation

An experimental use permit authorizes limited applications to gather data needed for registration or for new uses. Applying according to an existing registered label, a special local need label, or an emergency exemption does not require an experimental use permit.

Question 17Pesticide Laws, Regulations, and Certification Requirements

A grower wants to apply a pesticide to a crop that appears on a section 24(c) special local need label. The grower may:

  1. Apply it according to the SLN labeling for that state Correct answer.
  2. Apply it only if the product is unregistered
  3. Apply it at any rate because SLN labels are advisory
  4. Apply it only after obtaining a section 18 exemption

Explanation

A section 24(c) special local need registration is a state-specific label that must be followed exactly, including rates, sites, and precautions. SLN labeling is not advisory, and an additional section 18 exemption is not needed for a valid SLN use.

Question 18Pesticide Laws, Regulations, and Certification Requirements

Under the Worker Protection Standard, a restricted-entry interval is the:

  1. Interval between pesticide applications to the same field
  2. Time allowed for mixing and loading
  3. Period after application when entry is restricted Correct answer.
  4. Maximum time a worker may stay in a treated field per day

Explanation

The restricted-entry interval is the period after a pesticide application during which entry into the treated area is restricted, usually to protect workers from exposure. It is not a mixing time, a daily work limit, or a retreatment interval.

Question 19Pesticide Laws, Regulations, and Certification Requirements

If a worker must enter a treated area before the restricted-entry interval expires, the employer may allow entry only if:

  1. The worker wears street clothes
  2. The label allows it and PPE is worn Correct answer.
  3. The application was made with a general use product
  4. The worker signs a waiver

Explanation

Early entry is allowed only when the label permits the specific early-entry task and the worker wears the required personal protective equipment. A waiver or ordinary clothing does not satisfy the Worker Protection Standard.

Question 20Pesticide Laws, Regulations, and Certification Requirements

Which pesticide product is exempt from EPA registration because its ingredients are considered minimum risk?

  1. A product with an emergency exemption
  2. A section 25(b) minimum risk product Correct answer.
  3. A restricted use pesticide
  4. A product containing a new active ingredient

Explanation

Section 25(b) of FIFRA exempts certain products whose ingredients are on EPA's minimum risk list from registration. Products with new active ingredients, restricted use pesticides, and emergency-exemption products do not qualify under that exemption.

Question 21Pesticide Laws, Regulations, and Certification Requirements

A company sells a pesticide that is not registered with EPA and makes pest-control claims on the label. This sale is:

  1. Lawful if the product is used in South Dakota only
  2. Lawful if the buyer is a certified applicator
  3. Lawful if the product is diluted before use
  4. Unlawful because the product is unregistered Correct answer.

Explanation

Selling or distributing an unregistered pesticide with pest-control claims is unlawful unless a specific exemption applies, such as an emergency exemption or minimum risk status. State lines, buyer certification, and dilution do not cure the lack of registration.

Question 22Pesticide Laws, Regulations, and Certification Requirements

Which item is generally required in a record of a restricted use pesticide application?

  1. The customer's Social Security number
  2. Date and location of the application Correct answer.
  3. The retail price of the product
  4. The applicator's home address

Explanation

Application records must identify the application, including the date and location, along with other required details such as the product, amount, and applicator. Home address, retail price, and Social Security number are not required record elements.

Question 23Pesticide Laws, Regulations, and Certification Requirements

When a certified applicator supervises a noncertified applicator using a restricted use pesticide, the certified applicator is:

  1. Not responsible for the application
  2. Excused if the noncertified applicator has read the label
  3. Responsible for ensuring label compliance Correct answer.
  4. Responsible only if present at the site

Explanation

Supervision carries responsibility for ensuring that the restricted use pesticide is applied according to the label and applicable regulations. The certified applicator cannot avoid responsibility simply because the noncertified person read the label.

Question 24Pesticide Laws, Regulations, and Certification Requirements

Which enforcement action can a regulatory agency use to immediately halt the sale or use of a pesticide that poses a serious hazard?

  1. A stop sale or use order Correct answer.
  2. A verbal warning only
  3. An experimental use permit
  4. A special local need label

Explanation

A stop sale, use, or removal order can halt distribution or use of a pesticide that is misbranded, unregistered, or otherwise in violation. Warnings, permits, and special local need labels do not serve that immediate enforcement purpose.

Question 25Pesticide Laws, Regulations, and Certification Requirements

Which certification category would an applicator need to treat a pond for aquatic weeds?

  1. Seed treatment
  2. Right-of-way pest control
  3. Structural pest control
  4. Aquatic pest control Correct answer.

Explanation

Aquatic pest control covers pesticide applications to water bodies such as ponds for weed or algae control. Seed treatment, right-of-way, and structural categories cover different application sites.

Question 26Pesticide Laws, Regulations, and Certification Requirements

In South Dakota, which entity administers the pesticide applicator certification program and enforces pesticide use requirements?

  1. South Dakota Department of Agriculture and Natural Resources Correct answer.
  2. The U.S. Environmental Protection Agency regional office
  3. South Dakota Department of Health
  4. South Dakota Game, Fish and Parks

Explanation

FIFRA sets the national framework and EPA registers pesticide products, but day-to-day certification of applicators and enforcement of use requirements are carried out by the state lead agency. In South Dakota that agency is the Department of Agriculture and Natural Resources. EPA retains oversight and can withdraw approval of a state program that is not adequately enforced.

Question 27Pesticide Laws, Regulations, and Certification Requirements

Under FIFRA, a restricted use pesticide is a product that:

  1. carries a label statement warning that it is highly toxic to fish and wildlife
  2. is packaged and sold only in containers larger than one gallon for agricultural use
  3. has been classified by EPA for use only by or under the direct supervision of a certified applicator Correct answer.
  4. has been voluntarily cancelled by the manufacturer because of safety concerns

Explanation

FIFRA allows EPA to classify a pesticide for restricted use when it may cause unreasonable adverse effects on the environment even when used as directed. Such products may be applied only by a certified applicator or by a noncertified person under the direct supervision of a certified applicator. Hazard statements on a label, container size, or cancellation status do not by themselves create restricted use status.

Question 28Pesticide Laws, Regulations, and Certification Requirements

A state regulatory agency may suspend or revoke a certified applicator's certification when the applicator:

  1. switches from private application work to commercial application work
  2. applies a pesticide only to the sites that appear on the product label
  3. uses a restricted use pesticide in a manner inconsistent with its labeling Correct answer.
  4. attends a recertification training course instead of retaking the written examination

Explanation

Certification is conditioned on complying with FIFRA and the state pesticide law, and misuse is a violation of both. A state may suspend, revoke, or refuse to renew certification for misuse, and may also assess civil penalties. Lawful label-directed applications and approved recertification activities are not grounds for action.

Question 29Pesticide Laws, Regulations, and Certification Requirements

Under the Federal Food, Drug, and Cosmetic Act, a raw agricultural commodity that carries a pesticide residue above the established tolerance is:

  1. considered adulterated and may not be sold in interstate commerce Correct answer.
  2. legal to sell, but only within the state where it was grown
  3. required to be blended with a clean lot before it is offered for sale
  4. legal to sell if the residue is below the level the buyer can detect

Explanation

A tolerance is the maximum residue level EPA has determined is safe for a specific pesticide on a specific commodity. Food containing a residue above that tolerance is deemed adulterated and cannot legally be moved in interstate commerce. Blending or dilution does not make an adulterated lot legal.

Question 30Pesticide Laws, Regulations, and Certification Requirements

Which practice is permitted under FIFRA even though the product label does not specifically instruct it?

  1. Applying the product in a manner the label expressly prohibits
  2. Applying the product at a rate higher than the label allows to control a heavy infestation
  3. Applying the product to a site that does not appear on the label
  4. Applying the product at a rate lower than the rate stated on the label Correct answer.

Explanation

FIFRA provides that using a pesticide at a dosage, concentration, or frequency less than that stated on the label is not using it in a manner inconsistent with the labeling. Applying to an unlisted pest on a labeled site, and using an application method the label does not prohibit, are likewise generally allowed. Exceeding the labeled rate, treating an unlabeled site, or ignoring a label prohibition is misuse.

Question 31Pesticide Label Comprehension and Compliance

A pesticide label bears the signal word WARNING. Which EPA toxicity category does this indicate?

  1. Category IV
  2. Category I
  3. Category II Correct answer.
  4. Category III

Explanation

Signal words track the four EPA toxicity categories: Category I uses DANGER (with POISON and a skull and crossbones when the hazard is oral, dermal or inhalation), Category II uses WARNING, and Categories III and IV use CAUTION. WARNING therefore signals a product of moderate toxicity, more hazardous than CAUTION products but less than DANGER products.

Question 32Pesticide Label Comprehension and Compliance

Which statement is required on virtually every registered pesticide label, regardless of the product's toxicity?

  1. Keep out of reach of children Correct answer.
  2. Danger-Poison
  3. A skull and crossbones symbol
  4. Restricted Use Pesticide

Explanation

FIFRA requires the statement 'Keep out of reach of children' on pesticide labels as a uniform child-safety warning. The other statements are conditional: the skull and crossbones and DANGER-POISON appear only on highly toxic Category I products, and the restricted-use statement appears only on products so classified.

Question 33Pesticide Label Comprehension and Compliance

On a pesticide label, the EPA Registration Number identifies:

  1. the manufacturing lot number
  2. the product's federal registration Correct answer.
  3. the contents' expiration date
  4. the state of first sale

Explanation

The EPA Registration Number is assigned when EPA registers the product and appears on the label as proof that the product is registered for the uses shown. Lot or batch numbers are separate manufacturing codes and are not the registration number.

Question 34Pesticide Label Comprehension and Compliance

Typical label storage directions for a pesticide call for keeping the product:

  1. inside a vehicle parked in the sun
  2. away from food and animal feed Correct answer.
  3. in unlabeled jugs kept near the mixer
  4. in paper bags for ventilation

Explanation

Labels direct that pesticides be stored in a secure, dry place apart from food, feed, seed and household items to prevent contamination and accidental poisoning. Storing products in unlabeled containers or in vehicles exposed to heat is contrary to label directions and can also degrade the product.

Question 35Pesticide Label Comprehension and Compliance

The personal protective equipment listed in a pesticide label's PPE section represents:

  1. the minimum protection required Correct answer.
  2. the maximum protection available
  3. an optional guideline for trainers
  4. a suggestion for sensitive individuals

Explanation

Label PPE statements set the minimum protection that must be worn for the listed handling tasks; applicators may wear more protection but not less. Wearing less than the label requires is a use inconsistent with the labeling.

Question 36Pesticide Label Comprehension and Compliance

A product labeled Restricted Use Pesticide may be applied by:

  1. any licensed pesticide dealer or clerk
  2. a certified applicator or a supervised worker Correct answer.
  3. any adult who has read the label thoroughly
  4. any county weed and pest supervisor

Explanation

Restricted use pesticides may be applied only by certified applicators or by persons under their direct supervision, unless the label states otherwise. Reading the label, holding a dealer license, or holding a government job does not by itself authorize application.

Question 37Pesticide Label Comprehension and Compliance

The first aid statement on a pesticide label should be read:

  1. before handling the product Correct answer.
  2. only after symptoms appear
  3. only when mixing concentrates
  4. by the physician after arrival

Explanation

The label's first aid section tells you what to do in the first minutes after an exposure, and those actions often depend on having supplies and information on hand before an incident. Reading it before handling the product lets you plan for spills, eye splashes and skin contact.

Question 38Pesticide Label Comprehension and Compliance

The ingredient statement on a pesticide label lists active ingredients:

  1. by brand name only
  2. with no percentages shown
  3. by name and percent by weight Correct answer.
  4. as coded numbers for proprietary reasons

Explanation

The ingredient statement gives each active ingredient's chemical or common name together with its percentage by weight in the product. Inert ingredients are identified only by the total percentage, and trade names alone do not satisfy the disclosure requirement.

Question 39Pesticide Label Comprehension and Compliance

A label lists a 14-day preharvest interval for tomatoes. This means the last application must be made:

  1. at least 14 days before harvest Correct answer.
  2. 14 days after transplanting
  3. no more than 14 days before harvest
  4. when the fruit is 14 days old

Explanation

The preharvest interval is the minimum number of days that must pass between the last application and harvest, so it sets a waiting period before harvest. It has nothing to do with transplanting dates or the age of the fruit.

Question 40Pesticide Label Comprehension and Compliance

A label states a 12-hour restricted-entry interval for the treated area. This means:

  1. entry is prohibited for 12 hours except as allowed on the label Correct answer.
  2. workers may enter without any PPE once 12 hours have passed since the application
  3. the product is no longer present on the foliage after 12 hours
  4. the treated area must stay posted with warning signs for 12 hours

Explanation

The restricted-entry interval is the period after application during which entry is prohibited, apart from specific exceptions the label or the Worker Protection Standard allows. Expiration of the REI removes the entry ban but does not mean residues are gone, and posting requirements are separate from the REI itself.

Question 41Pesticide Label Comprehension and Compliance

Under FIFRA, applying a registered pesticide in a manner inconsistent with its labeling is:

  1. permitted if the applicator accepts liability
  2. a violation of federal law Correct answer.
  3. allowed when the pest is not on the label
  4. acceptable if a crop consultant recommends it

Explanation

FIFRA makes it unlawful to use a registered pesticide in a manner inconsistent with its labeling, and this applies to applicators and their employers. Accepting liability or relying on someone's recommendation does not create an exception to the label.

Question 42Pesticide Label Comprehension and Compliance

A Section 2(ee) recommendation permits a certified applicator or consultant to recommend:

  1. a site the label does not list
  2. use of a restricted-use product without certification
  3. a pest not listed, on a labeled site Correct answer.
  4. a rate higher than the label maximum

Explanation

A 2(ee) recommendation may cover a target pest not listed on the label as long as the site, product and rates stay within the existing registration; it may also address lower rates, application methods, or tank mixes with fertilizer. It cannot add a new site, raise the rate above the label maximum, or waive certification requirements.

Question 43Pesticide Label Comprehension and Compliance

A Section 24(c) special local need registration is issued by:

  1. the county extension office
  2. the product's manufacturer
  3. EPA headquarters in Washington, D.C.
  4. the state, under FIFRA authority Correct answer.

Explanation

FIFRA Section 24(c) lets a state issue a special local need registration for a use that is within its borders, acting under authority delegated through its lead pesticide agency. EPA reviews these actions, but the state issues them, and manufacturers and extension offices have no authority to do so.

Question 44Pesticide Label Comprehension and Compliance

An emergency exemption under FIFRA Section 18 allows:

  1. use of a canceled product by any homeowner
  2. interstate shipment of unregistered products
  3. temporary use during a declared emergency Correct answer.
  4. permanent registration of a new active ingredient

Explanation

A Section 18 exemption lets a state or federal agency request temporary use of an unregistered pesticide, or an unregistered use of a registered one, to control an emergency pest situation. The authority is time-limited and use-specific; it does not create a permanent registration or open the product to general use.

Question 45Pesticide Label Comprehension and Compliance

Under FIFRA, the term labeling includes the label itself plus:

  1. only the container's outer packaging
  2. other written material that accompanies it Correct answer.
  3. the safety data sheets kept on file at the shop
  4. the dealer's invoice for the sale

Explanation

Labeling is broader than the label: it covers the label attached to the container and any other written or graphic material that accompanies the product, such as brochures, circulars and supplemental directions. All of that material carries the same legal weight as the container label.

Question 46Pesticide Label Comprehension and Compliance

Under the Worker Protection Standard, agricultural workers must receive:

  1. training only after an exposure incident
  2. a written pesticide inventory each month
  3. pesticide safety training before handling tasks Correct answer.
  4. an annual respirator fit test

Explanation

The WPS requires employers to provide pesticide safety training to workers before they begin work in an area where they may be exposed to pesticides, with refresher training at least every five years. Fit testing and inventory records are separate requirements tied to specific products and operations.

Question 47Pesticide Label Comprehension and Compliance

When a label permits chemigation, it generally requires the applicator to install:

  1. a separate irrigation well
  2. a working backflow prevention device Correct answer.
  3. application only at night
  4. approval from the local fire department

Explanation

Labels that allow injection through irrigation systems require properly functioning check valves and backflow prevention to keep pesticide from siphoning into the water supply. A separate well, fire department approval, and night-only application are not standard label conditions.

Question 48Pesticide Label Comprehension and Compliance

A label box titled 'Protection of Endangered Species' typically directs the applicator to:

  1. apply only by aircraft
  2. avoid applying near water entirely
  3. notify the U.S. Fish and Wildlife Service before each application
  4. consult county bulletins before applying Correct answer.

Explanation

These label statements generally refer the user to county-specific endangered species bulletins or EPA's Bulletins Live! system to determine whether a pesticide use limitation applies at the application site. The restrictions are geographically specific rather than a blanket ban on application near water.

Question 49Pesticide Label Comprehension and Compliance

Some labels require rotating among pesticide groups to manage resistance. The group number shown on the label refers to:

  1. the EPA toxicity category
  2. the container disposal code
  3. the year the product was registered
  4. the mode-of-action group Correct answer.

Explanation

Group numbers on pesticide labels come from the resistance action committees and identify products that share a site of action, so applicators can rotate to a different group and slow resistance. They are unrelated to toxicity categories, container codes, or registration dates.

Question 50Pesticide Label Comprehension and Compliance

Certified applicators must keep records of restricted use pesticide applications for at least:

  1. one year
  2. five years
  3. two years Correct answer.
  4. six months

Explanation

Federal regulations require certified applicators to maintain records of restricted use pesticide applications for a minimum of two years from the date of application. The two-year window matches the period during which inspections and enforcement actions typically occur.
