Response of Germinating and Early Season Soybeans to Flooding
May 30, 2019
Injury to germinating and seedling soybean from flooding depends on several factors, including soybean growth stage, flood duration, and air and soil temperature and varies the varieties. Pythium and Phytophthora are two diseases to scout for after flooding.

Soybean Disease Update
January 11, 2019
In 2018 an array of weather conditions led to the development of several soybean diseases. Excessive early season moisture and heavy rains during the season resulted in many fields being impacted by Phytophthora root and stem rot. Frogeye leaf spot developed early in some areas and continues to build in the state with more fields being affected.
Corn Disease Update
January 9, 2019
The 2018 crop season got off to a slow start with cold, wet conditions delaying planting in much of the state. Some seedling diseases developed in early planted corn, but with ample heat units the corn caught up quickly and most of the crop finished ahead of schedule. High relative humidity and rainfall drove the development of several leaf diseases mid-season.
