2. Pesticide Application Equipment - BMP’s
Program goals, design and curriculum development
Training contents
Pilot implementation (Accomplishments)

3. Program Goals Drift reduction
Pesticide applications in a more effective and efficient way
Introduce new technologies

4. Program Development
We received training at Cornnell University

5. Curriculum Development
Highly interactive (hands-on)
Classroom and field activities
English and Spanish
1-day workshop (at a minimum)
Innovative

6. Program Design Same location Same sponsor/partner Same equipment
Different classrooms

7. Program Design Conociendo su equipo Getting to know your equipment
Spanish (Flor Servin, Ofelio Borges)
20 participants
English: (Jaime Ramon &Gwen Hoheisel)
20 participants
Conociendo su equipo
(classroom Field)
Getting to know your equipment
Calibración de su equipo
(classroom Field)
Equipment calibration
Configuración del equipo
(classroom Field)
Equipment configuration
Each component would have a classroom time. All the information covered in the classroom would get put in practice in the field hands-on along with other exorcises.
Why did I want this type of design?
We wanted to give employers and employees the opportunity to receive the class at the same time using the same methods and materials.
We wanted to start with basic concepts such as the identification of the equipment
I really wanted to separate equipment calibration from configuration for purposes of this training. All workshop on calibration I have been exposed to presented a mixture of calibration and configuration that would be somewhat confusing. Thus I wanted to clearly understand the two different concepts and after that they could mix them if they wanted to.
Give enviromental factors and new technology the importance that they deserve when it comes to reduce drift.
Technología nueva y factores ambientales
(classroom Field)
New technology and environmental factors

8. Program Design Four groups of five people
Work on different activities & orchard scenarios
All were participants
Four groups of five in order to have everyone involved. We wanted everyone who attended the workshop to be able to leave knowing how to calibrate a sprayer.
Each one of the groups work on activities with different scenarios

9. Getting to know your Equipment

10. Getting to Know your Equipment

11. Equipment Calibration - Tools

12. Equipment Calibration – New Tools

13. Equipment Calibration
We developed a 6-step program to calibrate
Practiced with different orchard scenarios
Each group worked on a different scenario & tested them in the field

17. Equipment Configuration
Configuration is the manipulation of application equipment to improve the deposition and coverage reducing product loss and off target drift.

18. Gone = $36 of a $60/acre chemical
40-60% of your spray is lost to the ground or air.
(Landers 2006)
Gone = $36 of a $60/acre chemical

19. Factors Affecting Configuration
Canopy shape
Planting system (wall, trellis, vase)
Shape and height of the tree  
Air volume in canopy
Density of foliage
Sistema de plantación (pared, trellis, vaso)
Estado vegetativo
Forma y altura del árbol
Volumen y densidad del follaje

20. Configuration Factors
Fan (direction, speed and volume of air)
Environment or Weather

21. Configuration Factors
Pressure (droplet size)
Nozzles (type, droplet size, orientation)
Type of spray

23. Environmental Factors & Technology
Wind
Temp inversions
Temp and humidity

24. Environmental Factors & New Technology

25. Accomplishments WSDA & WSU
4 workshops (Granger, Naches, Quincy & Wenatchee)
2 partners (G.S Long & Growers League)

26. Accomplishments
Trained 86 people
Served 42 companies
