Research Triangle Park, North Carolina (January 15, 2014)--Golf course superintendents and other turf professionals now have two new powerful tools for consistent, long-lasting protection against a broad range of turf diseases. BASF has announced the U.S. Environmental Protection Agency (EPA) registration of Xzemplar™ fungicide and Lexicon™ Intrinsic™ brand fungicide.
Both products contain the active ingredient fluxapyroxad, brand name Xemium®, a new and versatile SDHI (succinate-dehydrogenase inhibitor). Fluxapyroxad is a highly mobile and very effective active ingredient that provides both preventative and curative activity on key turfgrass pathogens. Xzemplar fungicide is a solo product containing only fluxapyroxad. Fluxapyroxad delivers unmatched dollar spot control and will be a key product for turfgrass managers when Rhizoctonia spp. and other patch diseases are present.
Lexicon Intrinsic brand fungicide contains a 1:2 ratio of fluxapyroxad and the active ingredient in Insignia® SC Intrinsic brand fungicide. Lexicon Intrinsic is a next generation Intrinsic product with disease control and advanced plant health. Field trial results for Lexicon Intrinsic brand fungicide have shown it provides efficacious control on a variety of troublesome turfgrass diseases, including brown patch, dollar spot, summer patch and fairy ring, in addition to 22 other diseases.
“BASF continuously invests in research and development to bring superintendents new tools to effectively and efficiently maintain impeccable playing conditions,” said Dan Carrothers, SPD Marketing Manager, BASF Specialty Products. “The introduction of these two new innovative products, featuring the new active ingredient fluxapyroxad, provides superintendents solutions for consistent superior disease control.”
Research shows Xzemplar fungicide and Lexicon Intrinsic brand fungicide provide consistent, long-lasting protection against a broad range of turf diseases. In trials conducted during 2008-2013 by both university and private contract researchers, excellent disease control was observed.
• Trial results for Xzemplar fungicide have shown excellent control against dollar spot at all rates and spray intervals (14-28 day) on greens and fairways. In a fairway dollar spot trial at Penn State University in 2013, Xzemplar fungicide on a 21-day spray interval was the top performing treatment among 40 entries. On the final rating date, Xzemplar fungicide was the only treatment with no dollar spot present, while the untreated plots contained over 140 dollar spot lesions per plot.
• In a curative dollar spot trial on a Crenshaw Bentgrass putting green at the Pee Dee Research and Education Center of Clemson University, Xzemplar fungicide plots contained an average of 2 dollar spot lesions as compared to the untreated plots that contained over 20 lesions at 14 days after the application.
• Lexicon Intrinsic brand fungicide trials demonstrated efficacious control of a variety of diseases including brown patch, dollar spot, summer patch and fairy ring. In a trial conducted on SR7100 colonial bentgrass, no Rhizoctonia infection (brown patch) was observed in Lexicon Intrinsic brand fungicide plots at 21 days after application as compared to the untreated control plots that averaged 70.5 percent disease incidence at the Rutgers’ trial site.
• Similarly, in a trial conducted on “Baron” Kentucky bluegrass, Magnaporthe infection (summer patch) after 21 days following a preventative application the Lexicon Intrinsic brand fungicide treatments exhibited very low infection (1.8 percent), whereas the untreated plots averaged 58.2 percent disease incidence as seen in the turfgrass plots at Rutgers.
With the introduction of Xzemplar fungicide and Lexicon Intrinsic brand fungicide, BASF continues to expand its existing portfolio of fungicides for turfgrass managers.
Both Xzemplar fungicide and Lexicon Intrinsic brand fungicide are expected to be available for sale in 2014.
