Frank Rossi interviews Ken Rost, founder and CEO of Frost Spray Technologies, about the evolution and adoption of GPS guided precision spraying systems in golf course and turf management. They discuss the barriers to technology adoption, including early reliability issues with GPS systems and the advantages of the Novotel satellite system that Frost uses. Ken explains how their partnership with Greenkeeper App has simplified map creation and enabled superintendents to have better control over their spray applications. The conversation covers variable rate applications, productivity improvements, and the emerging role of drone spraying technology for hard-to-reach areas like native grass zones. Ken shares insights from recent research presentations with Wendell Hutchens and Dave McCall on spring dead spot mapping, demonstrating 80-85% reductions in chemical use through targeted applications. The discussion also touches on licensing requirements for drone applications and the potential for automation in spray technology, with Ken teasing new developments to be unveiled at GIS in Orlando.
