“One out of 10 applicators will have to deal with a drift complaint.” (Fred Whitford, Purdue Pesticide Program) Will Drift Affect You? Drift 2014
16
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
17
DATCP Investigates all reports and Prohibits “significant” drift “Significant” drift has a identifiable impact and that evidence supports drift. Drift 2014
18
Particle Drift - movement of spray particles during or after the spray application Vapor Drift - associated with volatilization (gas, fumes) Types of Drift Drift 2014
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 Drift Drift 2014

Try not to fall into the trap of declaring “I need to spray RIGHT NOW!”. Forcing an application under poor conditions almost always leads to drift or other errors. Factors Affecting Drift Drift 2014

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. http://www.driftwatch.org/
