Question 1Pesticide Laws, Regulations, and Licensing

Which Wyoming agency administers the state pesticide applicator certification and licensing program?

  1. Wyoming Game and Fish Department
  2. Wyoming Department of Agriculture Correct answer.
  3. Wyoming Department of Environmental Quality
  4. University of Wyoming Extension

Explanation

The Wyoming Department of Agriculture is the state lead agency for pesticide regulation, including applicator certification and licensing. Game and Fish, DEQ, and Extension may provide related information, but they do not issue pesticide applicator credentials.

Question 2Pesticide Laws, Regulations, and Licensing

Which state law is the primary statute governing pesticide application and applicator certification in Wyoming?

  1. Wyoming Environmental Quality Act
  2. Wyoming Weed and Pest Control Act
  3. Federal Insecticide, Fungicide, and Rodenticide Act
  4. Wyoming Pest Control Act Correct answer.

Explanation

The Wyoming Pest Control Act is the state statute under which pesticide applicators are certified and pesticide use is regulated. The Weed and Pest Control Act deals with county weed and pest districts, while FIFRA is the federal pesticide law.

Question 3Pesticide Laws, Regulations, and Licensing

Under Wyoming law, a private applicator is a person who uses restricted-use pesticides primarily to do what?

  1. Sell restricted-use pesticides to other applicators
  2. Apply pesticides for hire on another person's property
  3. Apply pesticides only in commercial greenhouses
  4. Produce an agricultural commodity on land owned or rented by the applicator or employer Correct answer.

Explanation

A private applicator applies restricted-use pesticides for agricultural production on land owned or rented by the applicator or the applicator's employer. Applying for hire or on property the applicator does not control generally requires a commercial credential.

Question 4Pesticide Laws, Regulations, and Licensing

Before a person may legally use a restricted-use pesticide in Wyoming, the person must generally do what?

  1. Hold a current Wyoming applicator certification or license Correct answer.
  2. Register the pesticide with the county clerk
  3. Complete a pesticide dealer application
  4. Obtain a Wyoming business license

Explanation

Restricted-use pesticides may be applied only by certified or licensed applicators, or by noncertified persons working under proper supervision. County registration, dealer applications, and business licenses do not authorize restricted-use pesticide application.

Question 5Pesticide Laws, Regulations, and Licensing

Applying a pesticide in a manner inconsistent with its label is best described as what?

  1. Permitted with verbal approval from the pesticide dealer
  2. A violation of state and federal law Correct answer.
  3. Allowed if the applicator records the reason
  4. Acceptable when the target pest is not listed on the label

Explanation

The label is legally binding, and use inconsistent with the label violates pesticide law. An applicator may not substitute personal judgment, dealer approval, or recordkeeping for the label directions.

Question 6Pesticide Laws, Regulations, and Licensing

What credential does Wyoming require for a person who applies pesticides for hire?

  1. A county weed and pest permit
  2. An EPA federal applicator badge
  3. A Wyoming Department of Health certificate
  4. A commercial applicator license issued by the Wyoming Department of Agriculture Correct answer.

Explanation

Commercial applicators must be licensed through the Wyoming Department of Agriculture. County weed and pest districts, EPA, and the Department of Health do not issue the state commercial applicator license.

Question 7Pesticide Laws, Regulations, and Licensing

Which person is acting as a commercial applicator?

  1. A farmer applying a restricted-use herbicide to their own cropland
  2. A landscaper applying pesticides for hire on customers' properties Correct answer.
  3. A store clerk selling lawn fertilizer
  4. A manufacturer producing pesticide containers

Explanation

A commercial applicator applies pesticides for hire or on property not owned or rented by the applicator. A farmer treating their own land is generally a private applicator, and manufacturing or selling fertilizer is not pesticide application.

Question 8Pesticide Laws, Regulations, and Licensing

What should an applicator do first before mixing or applying a pesticide?

  1. Check the current market price of the product
  2. Ask a neighbor about last year's results
  3. Review the previous year's crop report
  4. Read and follow the product label directions Correct answer.

Explanation

The label provides the legal directions for use, including rates, sites, precautions, and restrictions. Applicators should read the label before mixing or applying, not rely on informal advice or price information.

Question 9Pesticide Laws, Regulations, and Licensing

Which Wyoming certification category applies to herbicide work along roadsides and utility rights-of-way?

  1. Agricultural plant pest control
  2. Industrial, institutional, and health pest control
  3. Aquatic pest control
  4. Right-of-way pest control Correct answer.

Explanation

Right-of-way pest control covers applications to roadsides, utility lines, and similar corridors. Aquatic, agricultural plant, and industrial/institutional categories cover different use sites.

Question 10Pesticide Laws, Regulations, and Licensing

A client asks an applicator to treat a pond for algae. Which certification category is most directly required?

  1. Forest pest control
  2. Right-of-way pest control
  3. Ornamental and turf pest control
  4. Aquatic pest control Correct answer.

Explanation

Pesticide applications to ponds and other water bodies fall under the aquatic pest control category. Turf, right-of-way, and forest categories address terrestrial sites rather than water.

Question 11Pesticide Laws, Regulations, and Licensing

A noncertified employee of a licensed commercial applicator may apply a restricted-use pesticide only under what condition?

  1. Under the supervision of a certified applicator Correct answer.
  2. Freely, because the employer holds the license
  3. Without supervision if the product is general-use
  4. Only after 30 days on the job

Explanation

Noncertified applicators may handle restricted-use pesticides only while working under the supervision of a certified applicator. The employer's license does not remove the need for supervision or certification.

Question 12Pesticide Laws, Regulations, and Licensing

Under the federal recordkeeping requirements that apply to restricted-use pesticide applications, how long must application records be kept?

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

Explanation

Certified applicators must keep records of restricted-use pesticide applications for at least two years. These records support enforcement and verification that the application followed the label.

Question 13Pesticide Laws, Regulations, and Licensing

A pesticide dealer may sell a restricted-use pesticide only to whom?

  1. A certified or licensed applicator Correct answer.
  2. Any person who is at least 18 years old
  3. A person holding a general-use permit
  4. A person who signs a liability waiver

Explanation

Restricted-use pesticides may be sold only to certified applicators or licensed applicators authorized to use them. Age, waivers, or general-use permits do not satisfy the restricted-use sale requirement.

Question 14Pesticide Laws, Regulations, and Licensing

An applicator's certification expires while they are still employed by a commercial applicator. What must the applicator do?

  1. Apply only general-use pesticides without any change
  2. Pay a late fee and continue applying restricted-use pesticides
  3. Stop applying restricted-use pesticides until recertified Correct answer.
  4. Continue applying restricted-use pesticides for 30 days

Explanation

Once certification expires, the person is no longer authorized to apply restricted-use pesticides until they are recertified. There is no automatic grace period created by continued employment.

Question 15Pesticide Laws, Regulations, and Licensing

Why does Wyoming require continuing education for applicator recertification?

  1. To increase pesticide dealer profits
  2. To satisfy county zoning requirements
  3. To keep applicators current on label changes and safe practices Correct answer.
  4. To replace the initial certification examination

Explanation

Continuing education helps certified applicators stay current on changing labels, regulations, and safe handling practices. It supports recertification but does not exist to benefit dealers or satisfy zoning rules.

Question 16Pesticide Laws, Regulations, and Licensing

A state registration allowing a pesticide to be used for a special local need within Wyoming is authorized under which FIFRA section?

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

Explanation

FIFRA Section 24(c) allows a state to register a pesticide for a special local need. Section 18 addresses emergency exemptions, and Section 3 covers federal registration of pesticides.

Question 17Pesticide Laws, Regulations, and Licensing

Which mechanism allows an unregistered pesticide use during a declared emergency, such as an unexpected pest outbreak?

  1. Section 18 emergency exemption Correct answer.
  2. Section 7 registration
  3. Section 24(c) special local need
  4. Section 3 registration

Explanation

A Section 18 exemption authorizes a temporary emergency use of a pesticide for an unregistered situation. Section 24(c) is for special local needs, while Section 3 is the standard registration process.

Question 18Pesticide Laws, Regulations, and Licensing

The Worker Protection Standard primarily protects which group?

  1. Wildlife in treated fields
  2. Pesticide dealers
  3. Homeowners applying lawn products
  4. Agricultural workers and pesticide handlers Correct answer.

Explanation

The Worker Protection Standard sets training, notification, and protection requirements for agricultural workers and pesticide handlers. It does not primarily regulate homeowners, dealers, or wildlife.

Question 19Pesticide Laws, Regulations, and Licensing

A label specifies a restricted-entry interval after application. What must the applicator do?

  1. Post the interval only at the dealer's office
  2. Shorten the interval if the weather is dry
  3. Allow entry if workers wear street clothes
  4. Keep workers out of the treated area for the stated period Correct answer.

Explanation

A restricted-entry interval requires workers to stay out of the treated area until the stated time has passed. Weather conditions or clothing do not authorize shortening the interval.

Question 20Pesticide Laws, Regulations, and Licensing

What is the first priority when responding to a pesticide spill?

  1. Cover the spill and leave the site
  2. Finish the application before cleaning up
  3. Protect people and contain the spill Correct answer.
  4. Wash the spill into a storm drain

Explanation

Spill response begins with protecting people from exposure and containing the material to prevent spreading. Washing a pesticide into a storm drain can cause environmental harm.

Question 21Pesticide Laws, Regulations, and Licensing

When may the Wyoming Department of Agriculture issue a stop sale or use order for a pesticide?

  1. Only after a court conviction
  2. Only for general-use products
  3. Only when a dealer requests one
  4. When the pesticide is misbranded or used in violation of law Correct answer.

Explanation

A stop sale or use order may be issued when a pesticide violates labeling or registration requirements or is being used unlawfully. A criminal conviction is not a prerequisite to exercising regulatory authority.

Question 22Pesticide Laws, Regulations, and Licensing

A pesticide is considered misbranded when its label does what?

  1. Contains false or misleading statements or lacks required information Correct answer.
  2. Includes a lot number
  3. Is printed in more than one color
  4. Is attached to a bulk tank

Explanation

Misbranding includes false or misleading label statements and missing required label information. Color, lot numbers, and bulk packaging are not by themselves grounds for misbranding.

Question 23Pesticide Laws, Regulations, and Licensing

How long must a restricted-use pesticide dealer keep records of restricted-use pesticide sales?

  1. 2 years Correct answer.
  2. 5 years
  3. 6 months
  4. 60 days

Explanation

Restricted-use pesticide dealers must retain sales records for at least two years. These records help regulators trace restricted-use products from dealer to certified purchaser.

Question 24Pesticide Laws, Regulations, and Licensing

Under FIFRA, using a registered pesticide against a pest that is not listed on its label is generally allowed when which condition is met?

  1. The pest is a regulated invasive species
  2. The applicator holds a private certificate
  3. The product is a general-use pesticide
  4. The application site is on the label and the label does not prohibit that use Correct answer.

Explanation

FIFRA generally allows a pesticide to be used against a pest not named on the label if the application site is listed and the label does not prohibit the use. The applicator still must follow all label directions and restrictions.

Question 25Pesticide Laws, Regulations, and Licensing

Who is responsible for ensuring that a noncertified applicator follows the label while working under a certified applicator?

  1. The county weed and pest supervisor
  2. The property owner where the work occurs
  3. The certified applicator supervising the work Correct answer.
  4. The pesticide dealer who sold the product

Explanation

The certified applicator who supervises noncertified applicators is responsible for ensuring that applications comply with the label and applicable law. Dealers, property owners, and county officials do not assume that supervisory duty.

Question 26Pesticide Laws, Regulations, and Licensing

A Wyoming landowner applies a restricted-use herbicide to cropland that he owns and farms himself to produce corn for market. How is he classified under Wyoming pesticide law?

  1. As a pesticide dealer
  2. As a commercial applicator
  3. As a private applicator Correct answer.
  4. As a noncertified handler

Explanation

A private applicator is a certified applicator who uses or supervises the use of restricted-use pesticides on land owned or rented by that person or the person's employer to produce an agricultural commodity. Applying only to one's own or rented production land is the defining feature, regardless of the size of the operation.

Question 27Pesticide Laws, Regulations, and Licensing

Which entity administers Wyoming's pesticide applicator certification and licensing program?

  1. Wyoming Department of Environmental Quality
  2. U.S. EPA regional office
  3. Wyoming Game and Fish Commission
  4. Wyoming Department of Agriculture Correct answer.

Explanation

The Wyoming Department of Agriculture administers the state pesticide law, including issuing applicator certifications, dealer licenses, and product registrations and conducting compliance inspections. Federal agencies set national standards under FIFRA, but day-to-day certification is a state function.

Question 28Pesticide Laws, Regulations, and Licensing

A manufacturer holds a federal EPA registration for a new insecticide and now wants to sell it to growers in Wyoming. What additional step is required before the product may be distributed in the state?

  1. Each county commission must approve the product Correct answer.
  2. The product must be registered with the Wyoming Department of Agriculture
  3. The product must be reclassified as general use
  4. The product must be retested by a university laboratory

Explanation

States operate their own pesticide registration programs, so a product must generally be registered with the state agency before it is sold or distributed there, in addition to holding an EPA registration. Wyoming requires state registration of pesticides distributed within its borders.

Question 29Pesticide Laws, Regulations, and Licensing

An applicator certified only in Wyoming's agricultural plant pest control category is asked to treat a commercial building for ants. What must be done before that applicator performs the work?

  1. A written waiver signed by the building owner
  2. A general-use registration for the building
  3. Certification in the structural pest control category Correct answer.
  4. Nothing, because certification authorizes any pest control work

Explanation

Certification is issued by category, and an applicator may legally perform only work covered by the category or categories held. Treating a structural site for ants falls outside agricultural plant pest control, so the applicator must be certified in the appropriate structural category or the job must go to someone who is.

Question 30Pesticide Laws, Regulations, and Licensing

What is the practical legal effect when EPA classifies a pesticide as restricted use?

  1. It may be sold only in containers larger than one gallon
  2. It may be applied only by employees of government agencies
  3. It may be applied only by or under the supervision of a certified applicator Correct answer.
  4. It may be used only on sites named in the Federal Register

Explanation

EPA classifies a pesticide as restricted use when it determines the product could cause unreasonable adverse effects without additional restrictions. The core restriction is that the product may be used only by a certified applicator or by a noncertified person acting under a certified applicator's supervision, as the label and regulations allow.

Question 31Pesticide Labeling and Safety Data Sheets

A pesticide label displays the signal word DANGER without the word POISON. This indicates that the product is:

  1. highly toxic or severely irritating to the skin or eyes Correct answer.
  2. exempt from federal registration requirements
  3. moderately toxic by the oral, dermal, or inhalation route
  4. slightly toxic and unlikely to cause injury

Explanation

DANGER is the signal word for Toxicity Category I products that are corrosive or cause severe eye or skin irritation, or that are highly toxic by one or more routes of exposure. When the product is also highly toxic by mouth, dermal absorption, or inhalation, the word POISON and a skull-and-crossbones symbol are added.

Question 32Pesticide Labeling and Safety Data Sheets

Which statement must appear on the front panel of a pesticide label regardless of the product's toxicity?

  1. Keep out of reach of children Correct answer.
  2. A statement of the product's pre-harvest interval
  3. A skull-and-crossbones symbol
  4. A restricted-use pesticide designation

Explanation

Federal labeling rules require the child-hazard warning "Keep out of reach of children" on the front panel of pesticide labels, placed with the signal word. The other items appear only on products that meet specific criteria.

Question 33Pesticide Labeling and Safety Data Sheets

The EPA registration number printed on a pesticide label identifies:

  1. the specific product and its approved uses as registered by EPA Correct answer.
  2. the factory where the product was manufactured or packaged
  3. the lot or batch of product contained in the package
  4. the state in which the product may legally be sold

Explanation

The registration number is assigned to a specific product formulation and its approved label uses, and its segments correspond to the company and product numbers. It stays with the product through changes in packaging or manufacturing location.

Question 34Pesticide Labeling and Safety Data Sheets

Which information belongs in Section 1 of a safety data sheet?

  1. Physical and chemical properties such as pH and vapor pressure
  2. First-aid measures and the most important symptoms of exposure
  3. Product identifier, recommended use, and supplier contact details Correct answer.
  4. Firefighting techniques and suitable extinguishing media

Explanation

Section 1, Identification, gives the product identifier and other means of identification, the recommended use and restrictions on use, and the name, address, and telephone number of the supplier, including an emergency phone number.

Question 35Pesticide Labeling and Safety Data Sheets

On a pesticide label, the pre-harvest interval is:

  1. the number of hours a worker must wait before entering a treated area
  2. the minimum number of days that must pass between the last application and harvest Correct answer.
  3. the period between mixing the spray solution and applying it
  4. the maximum number of applications permitted in a single season

Explanation

The pre-harvest interval is the waiting period between the final application and harvest, and it exists so that residues on the harvested commodity stay within the established tolerance. It applies to food and feed uses and may be stated differently for forage, grain, or the mature crop.

Question 36Pesticide Labeling and Safety Data Sheets

Who may legally apply a restricted-use pesticide?

  1. Anyone who has read the entire label
  2. Only employees of the company that manufactures the product
  3. A certified applicator, or a person under the direct supervision of a certified applicator Correct answer.
  4. Only licensed commercial pest control businesses

Explanation

Restricted-use pesticides may be applied only by or under the direct supervision of a certified applicator, and the supervision standard depends on whether the certification is private or commercial. The restricted-use statement appears near the top of the label.

Question 37Pesticide Labeling and Safety Data Sheets

The statement "It is a violation of Federal law to use this product in a manner inconsistent with its labeling" means that:

  1. only EPA may bring an enforcement action for label violations
  2. the label is only advisory once the product has been sold
  3. using the product in a way the label does not permit can result in civil and criminal penalties Correct answer.
  4. state law replaces the label once a product is registered in that state

Explanation

Under FIFRA it is unlawful to use a registered pesticide in a manner inconsistent with its labeling, and violations can lead to civil penalties and criminal prosecution. Enforcement is shared, with states typically handling use violations under EPA-approved programs.

Question 38Pesticide Labeling and Safety Data Sheets

A label carries the signal word WARNING. Which acute oral LD50 range corresponds to this toxicity category?

  1. More than 50 but not more than 500 mg/kg Correct answer.
  2. More than 5,000 mg/kg
  3. More than 500 but not more than 5,000 mg/kg
  4. 50 mg/kg or less

Explanation

WARNING corresponds to Toxicity Category II, which for acute oral exposure covers LD50 values greater than 50 and up to 500 mg/kg. Category I is 50 mg/kg or less, while Categories III and IV carry CAUTION.

Question 39Pesticide Labeling and Safety Data Sheets

A handler needs to know which respirator and gloves to wear while mixing a product. Which safety data sheet section contains this information?

  1. Section 3, Composition/information on ingredients
  2. Section 10, Stability and reactivity
  3. Section 8, Exposure controls/personal protection Correct answer.
  4. Section 7, Handling and storage

Explanation

Section 8 lists occupational exposure limits, appropriate engineering controls, and the individual protective measures such as gloves and respiratory protection. The label's PPE statements remain the enforceable requirement for using the product.

Question 40Pesticide Labeling and Safety Data Sheets

A worker splashes concentrated product into his eyes. Which safety data sheet section gives the emergency eye-flushing guidance?

  1. Section 16, Other information
  2. Section 6, Accidental release measures
  3. Section 9, Physical and chemical properties
  4. Section 4, First-aid measures Correct answer.

Explanation

Section 4 describes the first-aid measures needed for each route of exposure, including eye contact, along with the most important symptoms and effects. The label's first-aid statement is the primary field reference, and the safety data sheet expands on it.

Question 41Pesticide Labeling and Safety Data Sheets

A pesticide label states a 12-hour restricted-entry interval. What does this mean for workers?

  1. Workers may enter at any time if they wear long sleeves and long pants
  2. Workers must wait 12 hours before the product may be applied again
  3. Workers must wait 12 hours before the crop may be harvested
  4. Workers generally may not enter the treated area until 12 hours after the application ends Correct answer.

Explanation

The restricted-entry interval is the period after an application during which entry into the treated area is limited, and it begins when the application ends. Entry sooner is allowed only under the specific early-entry conditions in the Worker Protection Standard or in the label's own directions.

Question 42Pesticide Labeling and Safety Data Sheets

A state faces an emergency pest outbreak and no registered product exists for the situation. Under FIFRA Section 18, EPA may:

  1. waive the requirement that the product carry any label
  2. amend the product's federal registration permanently to add the use
  3. authorize an unregistered use for a limited period under an emergency exemption Correct answer.
  4. transfer enforcement authority for the product to the state agency

Explanation

A Section 18 emergency exemption permits a specific use of a pesticide for a limited time when an emergency pest problem exists and no registered alternative is available. The exemption carries its own labeling and conditions that users must follow.

Question 43Pesticide Labeling and Safety Data Sheets

Which mechanism allows a state to add a use to a federally registered pesticide label to address a pest problem that is special to that state?

  1. Section 24(c) special local need registration Correct answer.
  2. Section 3 registration
  3. Section 18 emergency exemption
  4. Section 25(b) minimum risk exemption

Explanation

FIFRA section 24(c) lets a state issue a special local need registration that adds a use needed within that state. The 24(c) labeling must be in the user's hands and is followed together with the base label.

Question 44Pesticide Labeling and Safety Data Sheets

Under FIFRA, the term "labeling" includes:

  1. only the printed material attached to the container
  2. the training materials used in a worker protection program
  3. the label itself plus brochures, circulars, and other written material that accompanies the product Correct answer.
  4. only the safety data sheet supplied by the manufacturer

Explanation

The label is the material attached to or accompanying the container, while labeling is broader and covers all written, printed, or graphic material that accompanies the pesticide or is referenced on it. Claims made in brochures or on a company website can therefore be part of the labeling.

Question 45Pesticide Labeling and Safety Data Sheets

Which statement about the personal protective equipment requirements on a pesticide label is accurate?

  1. They must be followed unless the label itself states a specific exception Correct answer.
  2. They may be reduced whenever a closed mixing system is used
  3. They may be relaxed when the weather is hot and humid
  4. They apply only to commercial for-hire applicators

Explanation

PPE statements are part of the label directions and are enforceable for anyone using the product. Only the exceptions written on the label, such as reduced protection for certain application methods or closed systems, permit less protective equipment.

Question 46Pesticide Labeling and Safety Data Sheets

A label contains chemigation directions. What must be installed when a pesticide is injected into an irrigation system?

  1. A sand filter at the end of each irrigation line
  2. A pressure gauge on the irrigation pump
  3. A flow meter of at least 4 inches
  4. A check valve and other equipment that prevent backflow into the water source Correct answer.

Explanation

Chemigation labels require equipment such as a functional check valve, vacuum relief valve, and low-pressure drain to keep pesticide from moving back into the water supply. The label may also require a metering pump interlock and specific operating procedures.

Question 47Pesticide Labeling and Safety Data Sheets

A label displays an "Agricultural Use Requirements" box. This box tells the user that the product is subject to:

  1. the tolerance requirements of FIFRA
  2. the laboratory chemical hygiene standard
  3. the Worker Protection Standard for agricultural workers and handlers Correct answer.
  4. the Clean Water Act permit program

Explanation

The Agricultural Use Requirements box appears on labels for products used on agricultural commodities and points users to the Worker Protection Standard. It states the restricted-entry interval and the post-application entry restrictions that apply to workers and handlers.

Question 48Pesticide Labeling and Safety Data Sheets

Which practice follows typical label storage and disposal directions?

  1. Storing the product in an unmarked plastic jug
  2. Keeping the product in its original labeled container with the closure secured, away from food and feed Correct answer.
  3. Burning empty containers in the field
  4. Pouring leftover spray mix into a floor drain

Explanation

Labels direct users to keep pesticides in their original labeled containers, closed and out of reach of children, and away from food, feed, and seed to prevent contamination. Disposal must follow the label and state rules, such as triple rinsing and recycling or proper landfill disposal of containers.

Question 49Pesticide Labeling and Safety Data Sheets

Under federal labeling requirements, the Directions for Use section of a pesticide label must state at least:

  1. the name of the certified applicator who will make the application
  2. the dealer's selling price for the product
  3. the sites of application and the pests the product is intended to control Correct answer.
  4. the manufacturer's warranty period

Explanation

The Directions for Use must include, at minimum, the site or sites of application and the pest or pests the product controls, along with any needed limitations. The label also gives rates, timing, and methods so the product can be used safely and effectively.

Question 50Pesticide Labeling and Safety Data Sheets

A label allows a broadcast application of 1 to 2 quarts per acre. An applicator treats the labeled site at 0.75 quart per acre. Under FIFRA, this application is:

  1. allowed only if the applicator records the reduced rate in a permanent log
  2. generally allowed, because applying less than the labeled rate is not inconsistent with the labeling unless the label prohibits it Correct answer.
  3. a violation unless the state extension service approves the lower rate in advance
  4. a violation, because any rate below the labeled range is misuse

Explanation

FIFRA's definition of using a pesticide in a manner inconsistent with its labeling excludes applying it at a dosage less than the labeled rate, unless the label specifically forbids lower rates. Lower rates can still lead to poor control and resistance, so the labeled range should guide the choice.
