Phytophthora Root Rot Alert
This past Friday, we observed phytophthora root rot notes near Bloomington, Illinois. This is a highly unusual occurrence and could repeat itself across the Midwest due to heavy rainfall, saturated souls, and elevated soil temperatures.
1.) Saturated Soils (Especially in low lying areas where water accumulates).
2.) Elevated soil temperatures (Phytophthora can hit any temperature and becomes most damaging as temps rise).
3.) The absence of a gene for specific race resistance
4.) Phytophthora tolerance is not directly linked to the presence of a specific gene. Varieties with average, or weak, phytophthora root rot tolerance are at risk.
5.) Ultimately, soybean plants without adequate phytophthora root rot protections will eventually die, having a direct impact on final yield.
