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. 

Key Factors:

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.
Fungicide Chart

As we approach pollination on the earliest planted field within the next 2 weeks, I wanted to pass along a recently updated fungicide chart from Purdue.

Storm Damage in Corn
by: Emerson Nafziger, University of Illinois

High winds hit parts of central and north-central Illinois on June 22 and 23, flattening corn that was at stages V10 to V13 or so (4 to 7 feet tall.) Hail damaged leaf area in some places as well, but hail was not as widespread as wind damage.
Figure 1 shows corn completely flattened at our Monmouth Research & Education Center, following wind gusts up to 78 mph between 2:45 and 3:00 AM on June 22. The detailed weather record indicates that rain started to fall at about that same time, and by 6:00 AM more than 2.5 inches had fallen.
