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

The 2021 Spray Clinic was held in July 202 and featured Dr. Tim Stombaugh, Dr. Jordan Shockley, Dr. Kiersten Wise, and Dr. Travis Legleiter of the University of Kentucky.   Topics covered during the day long in depth clinic included sprayer calibration, operation of pulse width modulation systems, , nozzle selection for herbicide applications, spray tank mixes, using apps to record weather conditions, nozzle selection for fungicide applications, and economics of sprayer sizing.   The field day was attended by 35 individuals from across the state of Kentucky who influenced approximately 29,000 acres of corn, soybean, and wheat.  Participant surveys indicated the field day gave them average of $11.47 per acre worth of knowledge lending to a potential $993,000 impact from the program based on the acreage influenced by the participants.
