Probability of yield response and breaking-even for soybean seed treatments. Crop Sci 52351-359. Conclusion and Recommendations Our study found differences in yield profitability and economic risk due to seed treatment and seed- ing rate.Growers should account for their expected grain sale price and seed treatment use when determin- ing their seeding rate and additionally the components of the seed treatment should be considered. We found that reducing seeding rates when using no seed treatment or a fungicide only seed treatment ApronMaxx might be too risky and provided minimal profit gains. In contrast this study also showed that a fungicideinsecticide seed treatment CruiserMaxx reduced economic risk and increased profit across an array of environments seeding rates 80000 140000 seeds per acre and grain sale prices 912 per bushel. Furthermore to realize the lowest risk and highest profit increase with CruiserMaxx pro- ducers should con- sider lowering their seeding rates to the EOSR according to their expected grain sale price. The EOSR for CruiserMaxx ranged from 94000 to 101000 seeds per acre and was on average 16 percent 18000 seeds per acre less than ApronMaxx and the UTC across grain sale prices of 912 per bushel.
