2011 Field Evaluation of Sunflower Hybrids and Breeding Lines for Resistance to Sclerotinia Head Rot - Carrington, Langdon, and Oakes, ND and Crookston, MN: The commercial and experimental hybrids Seeds 2000 ‘X9856’, Pioneer ‘63N82’, Croplan ‘343 DMR HO’, Genosys ‘8064’, and Pioneer ‘63ME70’ performed well across multiple locations. The hybrids Triumph ‘EXPSCL05’, Mycogen ‘E257321’, Syngenta ‘3990 NS/CL/DM’, Genosys ‘1068’, Sygenta ‘3995 NS/SU’, Mycogen ‘E378947’, and Croplan ‘EXP1141’, which were only screened at a single location, performed well in the Carrington screening nursery where they were evaluated.

2012 Field Evaluation of Commercial Lentil Varieties for Susceptibility to Sclerotinia - Carrington (summary): The small-green lentil ‘CDC Viceroy’, extra-small red lentil ‘CDC Impala CL’, and small-red lentil ‘CDC Maxim CL’ exhibited excellent tolerance to Sclerotinia and yielded well under high Sclerotinia disease pressure. Among medium-green lentils, ‘CDC Imigreen CL’ was less susceptible to Sclerotinia than ‘CDC Impress CL’; ‘CDC Richlea’ exhibited intermediate performance. The large-green lentils ‘Pennell’ and ‘Riveland’ performed poorly under high Sclerotinia disease pressure.

2012 Field Evaluation of Contans for Management of Sclerotinia Stem Rot: Evaluation of Application Rate and Timing (summary): Contans reduced both the viability and vigor of sclerotia, fall applications of Contans were more effective than spring applications, and Contans performed equivalently at 1 lb/ac and 2 lbs/ac. The results suggest that Contans may be a useful tool for degrading sclerotia of Sclerotinia sclerotiorum and reducing Sclerotinia disease pressure.

2012 Field Evaluation of Contans for Management of Sclerotinia Stem Rot: Evaluation of Incorporation Methods (summary): Under the conditions tested in this trial (sclerotia primarily on the soil surface at the time of Contans application and moist soils at the time of Contans application) manual incorporation of Contans (by harrowing to 1.5 inches), water incorporation (with 1 inch of water), and no incorporation performed similarly. Different results may be obtained when sclerotia are evenly distributed in the soil profile.

2012 Field Evaluation of Contans for Management of Sclerotinia Stem Rot: Spring Application Timing - Carrington (summary): Contans applications made in the spring sharply reduced the number of apothecia produced per sclerotium but had only a modest impact on the viability of sclerotia. Contans performed similarlly irrespective of when it was applied in the spring; applications made 2 days prior to planting soybeans performed similarly to applications made 38 days prior to planting soybeans.

2012 Field Evaluation of Contans for Management of Sclerotinia Stem Rot: Evaluation of Application Rate and Timing (technical report): Contans reduced both the viability and vigor of sclerotia, fall applications of Contans were more effective than spring applications, and Contans performed equivalently at 1 lb/ac and 2 lbs/ac. The results suggest that Contans may be a useful tool for degrading sclerotia of Sclerotinia sclerotiorum and reducing Sclerotinia disease pressure.

2012 Field Evaluation of Fungicides and Partial Host Resistance for Management of Sclerotinia Stem Rot on Soybeans - Carrington (summary): 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.
