Soybean Seed Treatment Evaluation

 

Soybean Seed Treatment Evaluation

Objectives

  • Evaluate seed treatment effects on grain yield among selected Pioneer® brand soybean varieties in Ohio and Michigan (Figure 1).
  • Measure yield at high pressure bean leaf beetle (BLB) locations.
     

Figure 1. Michigan and Ohio seed treatment locations, 2012 and 2013

Study Description

Years: 2012 and 2013 
Pioneer® Varieties Tested¹:      93Y05 (RR)
93Y84 (RR) - 2013
93Y91 (RR) - 2012
Treatments Tested: UNT = untreated check
FST = EverGol™ Energy + Allegiance® Fungicide
IST = FST + Gaucho® Insecticide
NST = FST + Poncho®/VOTiVO® insecticide/nematicide

Results

  • Although most 2013 locations had low to moderate seedling disease and insect pressure, average yield improved with fungicide treatment (Figure 2).
     

    Figure 2. 2013 grain yield of all varieties combined among seed treatments, 20 locations.

  • At locations where bean leaf beetle (BLB) pressure was greater than 10%, there was a significant yield advantage with insecticide seed treatment (Figure 3).
     

    Figure 3. 2012 and 2013 grain yield among treatments with > 10% BLB pressure, 10 locations.

These test results demonstrate significant value of Pioneer Premium Seed Treatment under both moderate and high disease and insect pressure.

Glyphosate Tolerant    R - Contains the Glyphosate Tolerant trait. Always follow grain marketing, stewardship practices and pesticide label directions. Varieties with the Glyphosate Tolerant trait (including those designated by the letter “R” in the product number) contain genes that confer tolerance to glyphosate herbicides. Glyphosate herbicides will kill crops that are not tolerant to glyphosate.
