Priaxor defends against Rhizoctonia, early blight, black dot

Are you seeing signs of Rhizoctonia, early blight or black dot? BASF has a product to help you fight back.

To help growers fortify their disease control toolbox, the company created Priaxor, a versatile fungicide that fits into multiple timings in a potato disease management program.

Depending on the disease growers are targeting, Priaxor has a fit in-furrow at planting, at rosette, and applications made at row closure or later.

Priaxor was researched extensively in potatoes,” said BASF Technical Service rep Curtis Rainbolt. “We observed suppression of Rhizoctonia and excellent efficacy on diseases such as early blight and black dot.”

“In addition to disease control, Priaxor provided plant health benefits which resulted in excellent potato yield and quality.”

Priaxor fungicide was created to bring growers a combination of F500, an active ingredient in Headline fungicide, and Xemium, an active ingredient found in Merivon fungicide. When applied in furrow, Priaxor offers growers an effective new tool for suppression of Rhizoctonia, Rainbolt said. Priaxor also has excellent activity on early blight, brown spot, and black dot.

“Priaxor combines the proven disease control of Headline fungicide (F500) that growers have used in the past with an additional site of action that is highly effective on a wide range of potato fungal diseases,” he said. “This offers a fungicide that is more effective, longer lasting and has two sites of action built in for resistance management.”

So how does it work?

As mentioned above, Priaxor contains two active ingredients. F500 is a Fungicide Resistance Action Committee (FRAC) Group 11 and Xemium is a FRAC Group 7 site of action fungicide. Both of these sites of action control fungal diseases by inhibiting energy production in the mitochondria of fungi cells, Rainbolt said.

“Without an energy source, the fungal cells cannot grow,” Rainbolt explained. “When applied to the leaves, a large portion of Priaxor is adsorbed into the waxy layer. As fungal spores land on leaf surfaces and germinate, they are unable to penetrate this layer of Priaxor.”

Growers can learn more about Priaxor by visiting www.agproducts.basf.us, or by contacting their local BASF representative.
