The purpose of this study is to evaluate fungicides, applied at the R3 growth stage across multiple soybean varieties, in an effort to determine yield and profitability.

2017 Southern Illinois Soybean Fungicide Study - Variety Response

Weather and disease pressure are two major factors that influence the effect of the performance of fungicides in a given year. The soybeans in this study were planted in late May and, with the exception of the month of July, did not receive many substantial rainfall events. With the lack of environment for disease pressure during critical reproductive stages, it’s not surprising that the use of a fungicide did not pay this year. Despite these results, past data has supported the use of fungicides and four-year data from Beck’s Southern Illinois PFR site has shown an average return on investment of $5.33/A. Multi-year data shows us that genetics can also impact the results, as BECK 354L4brand has shown the most benefit from fungicide applications.
