Soybean Seed Treatment Evaluation
- 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.

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