- Movement of spray particles and vapors off-target causing less
effective control and possible injury to susceptible vegetation,
wildlife, and people. Adapted from National Coalition on Drift
Minimization 1997 as adopted from the AAPCO Pesticide Drift
Enforcement Policy - March 1991 Definition of Drift Drift 2014
- Slide 17
- DATCP Investigates all reports and Prohibits significant drift
Significant drift has a identifiable impact and that evidence
supports drift. Drift 2014

- Particle Drift - movement of spray particles during or after
the spray application Vapor Drift - associated with volatilization
(gas, fumes) Types of Drift Drift 2014
- Slide 19
- Particle Drift More distinguishable, crosses rows, more severe
near source. Vapor Drift tends to follow low parts of the field,
less distinguishable, sometimes no pattern at all. Patterns of

- DriftWatch is a tool for identifying specialty crop sites and
to further enhance communications between producers of specialty
crops and pesticide applicators that promote awareness and
stewardship activities to help prevent and manage drift effects
that sometimes occur from spray operations.
