2012 Field Evaluation of Fungicides for Management of Sclerotinia on Soybeans - Carrington (technical report)
- Applied as a single application at early bloom (early R2 growth stage), Endura at 4 oz/ac, Endura at 8 oz/ac, Aproach at 12 fl oz/ac, and the tank-mix of Topsin at 20 fl oz/ac + Proline at 3 fl oz/ac exhibited a strong trend toward reduced Sclerotinia disease severity and increased yield relative to the control. However, additional testing will be needed to confirm that these treatments provide satisfactory disease control.

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 Contans for Management of Sclerotinia Stem Rot: Spring Application Timing - Carrington (technical report)
- 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 Incorporation Methods (technical report)
- 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: 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.
