Summary:
The corn, soybean and wheat fungicide segments have created a high demand for aerial application services and the need for greater application efficiency. Low water volumes in which fungicides are mixed and applied may offer solutions to improve efficiency and meet the growing demand for aerial services. BASF Corporation introduced 2 gallons per acre (gpa) carrier volume for Headline in 2007, reducing the required volume from 5 gpa, and is continually evaluating innovations in low volume applications. Although Headline is not currently registered for applications in carrier volumes less than 2 gpa, small-scale testing has been initiated to evaluate lower volume applications. Studies were conducted across the United States comparing selected application technologies. Headline applications were made to corn, soybean, or wheat. Evaluations included droplet size and distribution, coverage, disease control, and grain yield of the selected crops. Based on initial results, droplet size, distribution, and coverage are influenced by the technology used to make the Headline fungicide application. Further studies and evaluations are required to determine the best application methodology for Headline.
