Trial Objective

To demonstrate the fungal disease protection of PROLINE® 480 SC Foliar Fungicide on corn with the use of Climate FieldView™ Platform.

  • PROLINE® 480 SC Foliar Fungicide is a Group 3 (prothiconazole) fungicide for the control or suppression of labeled diseases.
  • Corn yield potential can be reduced when fungal diseases develop.

Experiment/Trial Design

  • Plant a preferred DEKALB® brand corn product from the provided product list and map planting in Climate FieldView™ Platform.
  • Utilize field-scale (maximum of 40 acres) Market Development Agronomist (MDA) trial to demonstrate on-farm effectiveness and benefits of PROLINE® 480 SC Foliar Fungicide. Applications to be mapped in Climate FieldView™ Platform.
  • Within the trial total acreage, a minimum of two untreated passes (untreated checks, UTC) selected with the use of Climate FieldView™ Field Health imagery, should be left for comparison with the fungicide-treated acreage. UTC passes should be a minimum of two acres, combine width, and allow for a minimum of four combine header passes.
    • 60 feet (sectional control) wide x 1500 feet long
    • 100 feet wide x 900 feet long
    • 120 feet wide x 750 feet long
  • Ideally, fungicide applications should occur pre-tassel up to early R1 growth stage; however, fungicide applications can occur when western bean cutworm (WBC) insecticides are applied. Cooperators spraying to control WBC should spray the UTC areas with insecticide.
  • Treatments (Table 1):
    • Spray 125 ml/acre (316 ml/hectare) of PROLINE® 480 SC Foliar Fungicide over the areas covering treatment 2.
      • Minimum water volume of 10 gal/acre (100 L/hectare). 19.2 to 20 gal/acre (180 to 200 L/hectare) is preferable.
      • No adjuvant.
      • Spray 1/2 of tank.

  • Trial Evaluations
    • Plan unmanned aerial vehicle (UAV) flights to catch interesting situations.
    • Ratings and evaluations (walk field and evaluate representative areas for each treatment).
      • Fungal disease severity (FSEV) rating at R3 to R5 growth stages (Figure 3).
      • Staygreen (STGRN) rating at R5 growth stage (Figure 4).
      • Ear rot (Gibberella) severity rating (ERSR) at R5 growth stage (Figure 5).
      • Root lodging percent (RTLP) at harvest.
      • Stalk lodging percent (STLP) at harvest.
      • Intactness (INT) at harvest.
      • Percent moisture content (MST) at harvest.
      • Optional - test weight (TWT) at harvest.
      • Collect grain samples for lab analysis of deoxynivalenol (DON) and zearalenone (MDIC) at harvest.
    • Record field notes in EXCEL file.
    • Field should be harvested with one combine. At minimum, UTC and fungicide strips on each side of the UTC.

    • Figure three is showing the disease severity scale on corn plants, ranging from 1 (healthy) to 9 (severely diseased)

Understanding the Results

  • Climate FieldView™ Platform provided beneficial images and information to support the use of foliar fungicides.
    PROLINE® 480 SC Foliar Fungicide
    • Grain from treated corn contained slightly more moisture (0.24%) than untreated corn (Figure 6).
    • Average yield was 2.3 bu/acre greater for treated corn versus untreated corn (Figure 7).
    • Treated corn showed a reduction in the ppm of DON versus untreated corn (0.235 and 0.526, respectively) (Figure 8).
    • Treated corn with Gibberella ear rot pressure showed a yield increase of 4.8 bu/acre versus untreated corn (Figure 12).
