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.
