BASF’s new fungicides offer effective turf results, research shows

By and |  August 14, 2013

BASF discussed during the recent American Phytopathological Society annual meeting research regarding its Xzemplar fungicide and Lexicon Intrinsic brand fungicide. Both contain the active ingredient fluxapyroxad, whereas Lexicon Intrinsic brand fungicide also contains pyraclostrobin. The company said it expects United States Environmental Protection Agency registration for the products this fall.

Tested in trials from 2008 to 2013, the research showed that Xzemplar fungicide and Lexicon Intrinsic brand fungicide provide consistent, long-lasting protection against a broad range of turf diseases.

“The research indicates that the new active ingredient fluxapyroxad is absorbed quickly and evenly transported into turf leaves,” said Renee Keese, Ph.D., Biology R&D Project Leader, BASF. “The consistent uptake and delivery provide preventive and early curative disease control.”

The research presented at the meeting was conducted at many locations across the United States. During the trials, university and private contract researchers recorded multiple disease ratings highlighting disease severity.

Trial results for Xzemplar fungicide, with the active ingredient fluxapyroxad, showed excellent control against dollar spot at all rates and timings. When compared with BASF’s Emerald fungicide, Xzemplar fungicide provided faster dollar spot control in the first 14 days of the trials.

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, Lexicon Intrinsic brand fungicide showed 0 percent Rhizoctonia infection (brown patch) after 21 days. When left untreated, the turf averaged 70.5 percent disease incidence.

In a trial conducted on Baron tall fescue, Lexicon Intrinsic brand fungicide showed 1.8 percent Magnaporthe infection (summer patch) after 21 days. When left untreated, the turf averaged 58.2 percent disease incidence.

Lexicon Intrinsic brand fungicide controls economically important diseases from all four major fungi classes: Ascomycetes, Basidiomycetes, Deuteromycetes and Oomycetes. Lexicon Intrinsic brand fungicide contains a 1:2 ratio of fluxapyroxad to pyraclostrobin.

Lexicon Intrinsic and Xzemplar are expected to be available for sale spring 2014, according to BASF.
