*Combination of Acceleron® DX-109 Fungicide Seed Treatment/Acceleron® D-109 Fungicide Seed Treatment, Acceleron® DX-309 Fungicide Seed Treatment, and Acceleron® DX-612 Fungicide Seed Treatment/Acceleron® D-612 Fungicide Seed Treatment.
** XtendiMax® herbicide with VaporGrip® Technology is part of the Roundup Ready® Xtend Crop System, is a restricted use pesticide and must be used with VaporGrip® Xtra Agent (or an equivalent volatility reduction adjuvant).

Disease Ratings, % Weed control, yield, and moisture data were collected at each location.
UNDERSTANDING THE RESULTS
The Roundup Ready® Xtend Crop System can provide season long, broad spectrum weed control by implementing overlapping residual herbicides and planting into clean, weed-free field conditions (data not shown).
Weed control was consistently acceptable across all treatments (Figures 1a and 1b).
Disease pressure was inconsequential at each of the locations.
Yield response between treatments varied by location (Figure 2).
- The Across Location average yields showed the improved yield performance of the Premier Offer treatment relative to the other treatments (Figure 3).
- At a 90% confidence level the Premier Offer treatment showed statistically significant yield improvement from the Basic Offering but not the Grower Standard treatment (Figure 3).
KEY LEARNINGS
In this trial soybean product selection along with an in-season fungicide application consistently provided the highest yields.
In-season fungicide applications can provide enhanced disease protection along with potentially improved yield performance.
A grower should always consult their local sales representative and agronomist to select the appropriate variety for their specific environmental conditions and yield goal.
