Abstract/Contents:"In a replicated field at Arrowhead County Club, San Bernardino, CA, monthly preventative treatments of Heritage at 0.2 and 0.4 oz/1000 square feet and Lynx at 1.5 oz/1000 sq ft provided good to excellent control of summer patch compared to monthly applications of Bayleton at 4.0 oz/1000 sq ft or the non-treated control plots. Heritage and Lynx also provided significantly improved turfgrass quality compared to the Bayleton and non-treated plot, although Lynx applications did result in significant, but reversible damage to turf. Bayleton turfgrass quality and control ratings were not significantly higher than the non-treated control plots on many of the rating dates. Based upon these results, Heritage or Lynx would be good replacements for the commercial standard Bayleton. Due to their solid performance, as well as their high residual activity, the use of Heritage or Lynx should also result in fewer pesticide applications per season for control of summer patch."
