NASHVILLE, Tenn.—With the results of field trials from the 2011 season now available, three years of research show Priaxor fungicide provided effective disease control and consistent yield increases in a wide range of crops. Priaxor is expected to receive U.S. EPA registration in 2012.
Priaxor research was conducted on row crops as well as on some specialty crops, such as potatoes and tomatoes. Tested in field trials from 2009 through 2011, Priaxor is a premix composed of pyraclostrobin—the active ingredient found in Headline fungicide and Cabrio EG fungicide—and Xemium fungicide, a new active ingredient in the carboxamide family.
For specialty crop growers, recent studies have shown that Priaxor will be an important tool to help growers control the toughest diseases and produce marketable fruiting vegetables. Priaxor was found to be effective at controlling early blight and black dot in potatoes as well as powdery mildew and black mold in tomatoes. A recent trial in North Dakota found potatoes sprayed with Priaxor had a 1 percent severity of early blight compared to an untreated check with 40 percent severity.
