Questions and Answers

Which of the following best describes the relationship between a pesticide's toxicity and the risk it poses?

  • Risk is solely determined by the toxicity of the pesticide, regardless of exposure levels.
  • Risk is only relevant when considering delayed effects of pesticides.
  • Risk is the inverse of toxicity; higher toxicity leads to lower risk.
  • Risk is a direct product of both the pesticide's toxicity and the level of exposure. (correct)

What distinguishes local effects of a pesticide from systemic effects?

  • Local effects are long-term while systemic effects are short-term.
  • Local effects occur only on the skin, with the exclusion of respiratory tract and eyes, while systemic effects affect the entire body.
  • Local effects are easily studied while systemic effects are not well known.
  • Local effects manifest at the point of contact, while systemic effects result from absorption and circulation throughout the body. (correct)

Which scenario most accurately describes a route of pesticide exposure that leads to a systemic effect?

  • Inhaling pesticide spray while working in a poorly ventilated area. (correct)
  • Rubbing eyes after handling a treated plant.
  • Washing hands immediately after pesticide handling.
  • A pesticide contacting a cut or scrape on the skin during application.

Study Notes

Mold Remediation Products

  • Halogens are oxidizing agents that kill microorganisms by damaging cell membranes.
  • Quaternary ammonium compounds (quats) are used on surfaces.
  • Phenolics treat equipment and surfaces.

Formulation Definition

  • Formulation is the mixture of active and inert ingredients.
  • Inert ingredients don't have pesticide activity, but improve application, safety, handling, storage, or other final product characteristics.

Formulation Selection

  • Different formulations are needed for various pesticide types.
  • Consider intended use, application equipment, conditions, effective pest control, and potential damage to treated surface areas.
  • Choosing a less hazardous formulation with comparable effectiveness is ideal.

Emulsifiable Concentrates (EC)

  • Advantages: easy handling, storage, and measurement; little agitation needed; not abrasive; minimal residue.
  • Disadvantages: high active ingredient concentration; potential overdose or mixing errors; surface damage; skin absorption; strong odor; equipment corrosion; flammability.

Wettable Powders (WP)

  • Advantages: easy storage, transport, handling; less harm to treated plants, animals, or surfaces; reduced skin and eye absorption risk.
  • Disadvantages: require precise weighing; difficult to mix; require continuous agitation; abrasive to equipment.

Flowables (F or AF)

  • Advantages: low exposure risk; not phytotoxic; less splashing.
  • Disadvantages: need shaking before use; containers may be difficult or impossible to rinse; potential equipment abrasion; residue on treated surfaces.

Ready-to-Use or Pre-Mixed Sprays

  • Advantages: don't require mixing or measuring; reduce application risk; often delivered in special application devices.
  • Disadvantages: limited availability and higher per unit cost.

Pastes, Gels, and Baits

  • Advantages: odorless; low human toxicity; long-lasting; accurate placement, low risk of exposure.
  • Disadvantages: contamination from other pesticides or cleaning products; staining; repeated application buildup.

Dusts

  • Advantages: ready-to-use; good for areas where moisture harms application; simple application.
  • Disadvantages: high inhalation risk; potential for drifting; clumping.

Pesticide Health Concerns and Laws

  • Various pesticide formulations pose different health concerns.
  • Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) regulates pesticide production, transport, sale, use, and disposal in the US.
  • Environmental Protection Agency (EPA) is responsible for pesticide registration.

Pesticide Application Records

  • Applicators must record pesticide applications for at least two years. Records must include the specific site, full date, times of application, product name, and EPA registration number.
