14. Will Drift Affect You? “One out of 10 applicators will have to deal with a drift complaint.” (Fred Whitford, Purdue Pesticide Program) Drift 2014

15. Definition of Drift Movement of spray particlesand vaporsoff-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 Drift 2014

16. DATCP Investigates all reports and Prohibits “significant” drift “Significant” drift has a identifiable impact and that evidence supports drift. Drift 2014

17. Types of Drift Particle Drift - movement of spray particles during or after the spray application Vapor Drift - associated with volatilization (gas, fumes) Drift 2014

18. Patterns of Drift 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. Drift 2014

19. Preventing Problems • Think about the area surrounding each field. Grapes! Drift 2014

20. Preventing Problems • Think about the area surrounding each field. • Follow Label restrictions. Drift 2014

21. Preventing Problems • Think about the area surrounding each field. • Follow Label restrictions. • Calibrate spray equipment. Drift 2014

22. Preventing Problems • Think about the area surrounding each field. • Follow Label restrictions. • Calibrate spray equipment. • Be Considerate of neighbors. Drift 2014

23. Preventing Problems • Think about the area surrounding each field. • Follow Label restrictions. • Calibrate spray equipment. • Be Considerate of neighbors. • Respond courteously to complaints. Drift 2014

24. New Condition Sweeping the Nation A new condition is sweeping the nation, “Caller I.D. itis. This condition was first identified by the United States Center for Telephone Conduct. It is believed to be infecting millions . . . Drift 2014

32. 30 20 10 6 2 0 11 mph 10 mph 8 mph Height Above Crop Canopy, Feet 7 mph 5 mph Factors Affecting Drift Wind Speed The relation between height above the canopy of a crop like cotton or soybean and the speed of wind. Drift 2014

33. Factors Affecting Drift • Weather Characteristics • Wind direction/velocity • Temperature and humidity • Air stability/inversions • Topography Drift 2014

34. Factors Affecting Drift 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. Drift 2014

35. Probably not the best time to spray Drift 2014

36. 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/ Drift 2014

37. Minimizing spray drift is in the best interests of everyone. Do your part to keep pesticide applications on target. Drift 2014
