** 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.

• 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).

• 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.
