Soil moisture in many regions of Iowa is at field capacity or more so planting will occur in wet soils this spring. Wet soils increase the risk of damping-off in soybean by the fungi Phytophthora and Pythium. Seedling disease concerns are further compounded this year by low-to-poor seed quality. If damping-off occurs this year, growers may have difficulty finding soybean seed for replanting and may want to consider the following strategies for controlling Phytophthora and Pythium damping-off.
