Bidermann Golf Course opened in 1965 after founding member George Weymouth and owner of Winterthur estate Henry F. du Pont agreed to expand upon the estate’s 9-hole golf course. Named after du Pont’s accountant, Antoine Bidermann, the course joined the Vicmead Hunt Club in 1977 to offer a full service country club to members.

Golf course superintendent John Urbanski and his crew of 22 supplement pesticide applications with cultural controls such as topdressing, aerification and needle tining of the greens to manage regional disease pressures.

Twenty of the 70 maintained acres of roughs and 50 acres of native meadow roughs are not treated with pre-emergent herbicide and are highly susceptible to crabgrass infestation. Urbanski’s crew mixes Drive® herbicide with a spray adjuvant and applies it at 16 ounces per acre with a boom sprayer to control breakthroughs.

“Drive is our number one crabgrass postemergent control for roughs,” said Urbanski. “The crabgrass wilts and dies after a few days and control is achieved with a single application.”
