2012 Field Evaluation of Fungicides and Partial Host Resistance for Management of Sclerotinia Stem Rot on Soybeans - Carrington (technical report)
-
Under moderate Sclerotinia disease pressure, Endura but not Proline or Cobra applied as a single application at early bloom (early R2 growth stage) significantly reduced Sclerotinia stem rot relative to the control. Under the narrow 7-inch row spacing used, fungicides were a more effective tool for managing Sclerotinia stem rot than the use of partially resistant varieties.

2012 Field Evaluation of Fungicides for Management of Anthracnose and Sclerotinia on Lentils - Carrington (technical report)
-
Under high anthracnose disease pressure, the registered fungicides Headline and Priaxor provided good disease control and a strong yield response. It was not immediately apparent that Priaxor, which is a premix of the active ingredient found in Headline and another active ingredient, provided an advantage over Headline. When applied as two sequential applications, Endura, Proline, and Vertisan did not provide satisfactory disease control. Quadris showed intermediate performance.

2012 Field Evaluation of Fungicides for Management of Anthracnose on Dry Edible (pinto) Beans - Carrington (technical report)
-
Fungicides that contained azoxystrobin or pyraclostrobin active ingredients (Headline, Quadris, Quadris Opti, and Priaxor) provided good control of foliar anthracnose symptoms, but it was unclear whether any fungicides might provide satisfactory control of anthracnose related seed discoloration. Due to drought stress and high soil salinity at the site used for this trial, the yield response to using fungicides to control anthracnose could not be properly assessed.

2012 Field Evaluation of Fungicides for Management of Anthracnose on Lentils - Sykeston (technical report)
-
The registered fungicides Headline, Priaxor, and Quadris gave good control of anthracnose. It was not immediately apparent that Priaxor, which is a premix of the active ingredient found in Headline and another active ingredient, provided an advantage over Headline. When applied as two sequential applications, the registered fungicides Endura, Proline, and Vertisan did not provide satisfactory disease control.

2012 Field Evaluation of Fungicides for Management of Anthracnose on Lentils - Williston (technical report)
-
Under moderate anthracnose pressure, the registered fungicides Headline, Priaxor, and Quadris performed well. When applied as two sequential applications, Endura and Proline did not provide satisfactory disease control. Vertisan showed intermediate performance. Disease development occurred late in crop development, and the yield response to fungicide usage was low.

2012 Field Evaluation of Fungicides for Management of Ascochyta Blight of Chickpeas - 25 miles east of Williston (technical report)
-
Priaxor and Proline both performed well; rotational strategies with Proline and Priaxor performed equivalently as sequential applications of either product; and the 4 fl oz/ac application rate of Priaxor was sufficient. Additional data is needed to evaluate whether Vertisan may perform equivalently to Priaxor when applied in rotation with Proline.

2012 Field Evaluation of Fungicides for Management of Ascochyta Blight of Chickpeas - Carrington (technical report)
-
Disease pressure was inadequate to rigorously assess fungicide efficacy in this trial, but the disease control trends were very similar to those observed in the parallel trial conducted in Williston in 2012. To ensure more informative results in future trials, irrigation will be used in future chickpea fungicide trials in Carrington when the weather is unfavorable for disease development.

2012 Field Evaluation of Fungicides for Management of Ascochyta Blight on Lentils - Carrington (technical report)
-
Under heavy Ascochyta blight pressure, the registered fungicides Headline and Priaxor performed well. It was not immediately apparent that Priaxor, which is a premix of the active ingredient found in Headline and another active ingredient, provided an advantage over Headline. The registered fungicides Endura, Proline, Quaris, and Vertisan did not provide satisfactory disease control.

2012 Field Evaluation of Fungicides for Management of Mycosphaerella Blight of Field Peas - Carrington (technical report)
-
The registered fungicides Headline, Proline, and Priaxor provided excellent control of Mycosphaerella blight. Endura and Vertisan did not perform as well. There was a slight trend towards higher yield and better disease control as the application rate of Priaxor increased from 4 to 6 fl oz/ac.
