They looked at 4 formulations of fungicide products across all of these trials. Because insects and fungal diseases often attack agricultural crops late in their growing seasons, aerial application may be the only method available to control these pests and diseases in an attempt to reduce significant losses in crop yield. This includes passing a medical exam and flying for 250 hours. The aircraft ranges in price from $100,000 to $1.5 million and utilize sophisticated precision application technologies such as GPS (global positioning systems) and GIS (geographical information systems), flow controls, and precisely calibrated spray application equipment to make sure the pilot is accurate in applying the product to the crop.
