Air Assisted Sprayer Demonstration & Calibration Field Day

Air Assisted Sprayer Demonstration & Sprayer Calibration Field Day – Jim Jasinski, OSU Extension IPM Program; Erdal Ozkan & Mike Sword, Dept. of Food, Agricultural, and Biological Engineering

There will be a field day from 5-7 PM on August 8^th at the Western Agricultural Research Station highlighting research on the use of a custom built Jacto air assisted sprayer to increase efficacy of fungicides applied to large canopy crops, such as pumpkin.  The use of air assisted technology helps spray droplets penetrate deeper into the canopy and increase deposition on the lower leaf surface, which greatly improves efficacy against diseases like powdery mildew, especially for contact materials. This technology can also be useful in increasing efficacy when applying insecticides.

The field day will cover the following topics:

• Review 2012 air assist sprayer results on pumpkin
• Have custom designed air assist Jacto sprayer conduct demonstrations in thefield using different nozzle types (flat fan, twin fan, hollow cone) with and without air assist.  Water sensitive cards attached to poles in crop canopy will be used to show spray penetration into the canopy.  Target crop is pumpkin but concept may apply to other crops with large complex canopy.
• Following air assist discussion and demonstration, a clinic will be held reviewing the proper techniques to perform sprayer calibration.
• Jacto Sprayer company representatives will be on hand for growers to interact with during the field day.
