Methodology

WinField CP2450XF soybeans and Hefty H25XF4 soybeans were planted on May 29, 2024, in 30-inch rows at 100,000 seeds per acre in Douglas County. Stratego YLD fungicide was applied to both varieties of soybean on August 5, 2024 at a rate of 4 fl oz/ac. The contents of this product are listed in the documents below the yield map. Stratego YLD fungicide was applied in 90 ft wide strips. The soybeans were harvested on October 7, 2024 and October 8, 2025.

Results

Hefty H25XF4 soybeans treated with Stratego YLD fungicide yielded 2.0 bu.ac less than the WinField CP2450XF soybeans treated with Stratego YLD fungicide. This was a smaller difference than 3.4 bu/ac and is therefore not significantly different at the 90% confidence level (Table 1). To validate these results, additional testing of these varieties with Stratego YLD fungicide would be beneficial.
