Fairy Ring suppressed by Combining DryJect with Profile® Field & Fairway describes the use of DryJect to inject Profile Field & Fairway into fairways with severe Type I and II fairy ring. Trials at Philadelphia Country Club showed plots treated once or twice remained essentially symptom-free up to two years later, with reduced wilt stress and increased infiltration, water holding capacity and porosity. A cost comparison outlines DryJect with Profile Field & Fairway as a “green alternative” to repeated chemical applications, providing aeration, improved root systems, firmer fairways and potential water savings while reducing annual per-acre treatment costs.
Key Points
- Injecting Profile Field & Fairway via DryJect reduced Type I and II fairy ring symptoms, with treated fairway plots remaining symptom-free when evaluated in January 2009, including plots first treated in 2007.
- Treated turf showed less wilt stress and improved soil conditions, with infiltration rates 2% higher after one injection and 18% higher after two injections than non-injected plots, along with increased water holding capacity and water porosity.
- The DryJect “green alternative” applies 3.5 tons of Profile Field & Fairway per acre, aerates fairways, avoids chemical use, and has observed benefits including improved root systems, firmer fairways and water savings.
- Compared with chemical programs costing $2,578.00–$2,980.52 per acre annually, DryJect with Profile Field & Fairway costs $2,800.00 per acre per application, assumed once every other year, or $1,400.00 per acre per year.
