Pesticide Registration

Tests:

  • Environmental fate
    • Movement
      • Runoff
      • Leaching
      • Drift

Pesticide Registration

Tests:

  • Ecological effects
    • Birds
    • Fish
    • Non-target plants

Pesticide Registration

Tests:

  • Residue Analysis

Pesticide Registration

Residue Analysis:

Pesticide applied according to proposed label rates & procedures.

Then pesticide residues on crops are measured.

pesticide tolerances
Pesticide Tolerances

The amount of pesticide residue that will be legally allowed on food.

Tolerance Setting

Pesticide Registration

If residue < tolerance,

Pesticide registered

“Reasonable certainty

that no harm will result

from aggregate pesticide exposure”

slide29

The

Risk Cup

EPA has compared setting tolerances to filling a “Risk Cup”

slide30

The

Risk Cup

Exposure that you could receive every day.

For 70 years.

With no significant risk of long term, health effects.

Common Mode of Action

Guthion

EPA must consider

aggregate exposure

Pets

Home

Water

Garden

Food

slide35

Aggregate Exposure

Chlorpyrifos(Dursban, Lorsban)

slide36

Dietary/ Non-Dietary Exposure

&

Common Mechanism of Toxicity

slide37

If the risk cup gets full,

manufacturers could reduce risk…

slide38

By eliminating uses…

… Especially minor uses!

  • Methyl parathion
  • Azinphos methyl
  • Chlorphyrifos
  • Bendiocarb
  • Ethyl parathion
slide40

Changes in pesticide labels to reduce risk?

  • Reduce number of sprays
  • Reduce application rate
  • Change formulation
