Importance of Fungicide Seed Treatments in 2020

For many Illinois farmers, the last few springs have been wetter than most and with soil moisture already at high levels in some areas, the use of fungicide seed treatments at planting in 2020 should be considered. Fungicides are an important tool in any farmer’s toolbox because they help protect against soil-borne and seed-borne pathogens that have the potential to hurt germination or even infect the seedling early in its life cycle.

Additionally, farmers have been planting soybeans earlier to take advantage of the potential yield bump that we are seeing from earlier planting dates.1 Earlier planting dates typically have higher soil moisture content and lower soil temperatures. These conditions are conducive for the development of diseases that can cause early season damping off such as Phytophthora and Pythium.

When we look at field trial research performed at the Bayer Learning Center at Monmouth, Illinois, in the 2018 and 2019 growing seasons, we see that Acceleron® Seed Applied Solutions STANDARD treated soybean seed showed a yield advantage in both early and late planting dates versus an untreated check. In the early planting dates, Acceleron® Seed Applied Solutions STANDARD showed an average 8.8 bu/acre yield advantage over the untreated check and an average 4.2 bu/acre advantage for late planting dates when soil conditions were warmer and more ideal. Seedlings treated with Acceleron® Seed Applied Solutions STANDARD appeared healthier and more vigorous after emergence (Figure 1) when compared to untreated seed.

When making decisions for the 2020 growing season, consider including a soybean fungicide seed treatment. It helps protect against less than ideal environmental conditions while taking advantage of the potential yield increase of an early soybean planting date.
