RESEARCH TRIANGLE PARK, N.C.-BASF discussed research regarding Merivon fungicide and Priaxor fungicide at the American Phytopathological Society (APS) annual conference. Merivon and Priaxor both contain the new active ingredient fluxapyroxad, trade name Xemium fungicide, as well as pyraclostrobin. EPA registration for the products is expected in early 2012.
Priaxor research was conducted primarily on row crops, as well as some specialty crops, such as potatoes and tomatoes.
Tested in field trials in 2009 and 2010, Priaxor is a premix composed of pyraclostrobin-the active ingredient found in Headline fungicide-and Xemium, a new active ingredient in the carboxamide family. Results indicate Priaxor will provide long-lasting preventative and disease-stopping protection as well as good coverage of the leaf surface and systemic distribution to ensure optimum coverage.
Priaxor was found to be effective at controlling early blight in potato and tomato, powdery mildew and black mold in tomato and black dot in potato trials. Tomatoes treated with Priaxor showed a 20 percent less incidence of early blight than those treated with a competitive product.
