The application of herbicide and fungicides for control of weeds and plant diseases can be very costly and incorrect applications can lead to exponential cost, crop loss, and potential litigation if drift occurs.  The appropriate calibration of a sprayer, nozzle selection, and clean out following are all complicated procedures that can fluctuate depending on the product being applied.  

The 2018 Spray Clinic was held in July 2018 and featured Dr. Tim Stombaugh, Dr. Kiersten Wise, Dr. Carl Bradley, and Dr. Travis Legleiter of the University of Kentucky as well as Dr. Fred Whitford of Purdue University.  Topics covered during the day long in depth clinic included sprayer calibration, sprayer clean-out and winterization, nozzle selection for herbicide applications, and nozzle selection for fungicide applications.  The field day was attended by individuals from across the state of Kentucky who influenced approximately 160,000 acres of row crops.  Participant surveys indicated the field day gave them approximately $11 per acre worth of knowledge lending to a potential $1.7-million impact from the program based on the acreage influenced by the participants.
