Study Notes

Mold Remediation Products

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

Formulation Definition

  • A formulation is a mixture of active and inert ingredients
  • Inert ingredients don't have pesticide activity but improve application, safety, and handling.

Different Formulations

  • Pesticides are more effective in certain formulations
  • Consider intended use, application equipment, target reach, potential surface damage, and alternative less hazardous options.

Emulsifiable Concentrates (EC)

  • Advantages: easy to handle, transport, store, measure, and require little agitation; leave little visible residue
  • Disadvantages: high concentration, potential for overdose or mixing/calibration errors; may damage surfaces, easily absorbed through skin, splashes and spills are difficult to clean, may have a strong odor and be corrosive to application equipment, flammable

Wettable Powders (WP)

  • Advantages: easy to store, transport, and handle; less likely to harm treated plants, animals, and surfaces; not phytotoxic; less risk of skin/eye absorption
  • Disadvantages: must be weighed, difficult to mix; requires good and constant agitation in the spray tank; abrasive to pumps and nozzles

Flowables

  • Advantages: low exposure risk, not phytotoxic, seldom clog nozzles; splashes are less likely compared to other liquid formulations
  • Disadvantages: need shaking before measuring and mixing; containers may be difficult to rinse; require moderate agitation; may leave a visible residue

Ready-to-Use or Pre-mixed Sprays

  • Advantages: neither measuring nor mixing is required; some are packaged with application devices; less personal exposure risk
  • Disadvantages: limited availability, high cost per unit of active ingredient

Pastes, Gels, and Injectable Baits

  • Advantages: odorless; low toxicity to humans; long-lasting; low exposure risk; effective at minimizing human and pet exposure; highly accurate placement and dosage
  • Disadvantages: becomes contaminated when exposed to other pesticides or cleaning products; may run and drip at high temperatures; may stain porous surfaces; repeated applications can cause unsightly buildup

Dusts

  • Advantages: usually ready-to-use; good alternative where moisture may damage application; simple application equipment
  • Disadvantages: easily drifts off target; may irritate eyes, nose, throat and skin; risk of inhalation exposure; dampness can cause clumping; uneven distribution of particles

Solid Baits

  • Advantages: ready-to-use; entire area doesn't require coverage; controls pests that move in and out of an area
  • Disadvantages: may be attractive to children and pets; may kill domestic animals or non-target wildlife; requires careful placement; pest may prefer other food to the bait; undesirable odor from dead vertebrate pests

Other Information

  • Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) is the prominent US federal pesticide law
  • EPA registers pesticide products for sale and use
  • Some products are classified "restricted-use" to be used only by trained personnel
  • State laws can be stricter than federal laws, but cannot be less stringent
  • Commercial and private applicators have specific use roles and responsibilities
