Nine Species of Pythium Associated with Corn Seeding Blight in Southeastern Iowa

Abstract

<p>During the 2012 growing season, several thousands of acres of corn in southern Iowa were replanted in late May because of <a href="http://bit.ly/KgLjNx">poor stands caused by seedling disease</a>. Many of the fields affected were planted between April 23 and 27. From April 28 through May 8, 2 to 6 inches of rain fell across southern Iowa and southeastern Iowa, respectively, and soil temperatures dropped below 55°F for four to five days. Approximately, one week later, damped off seedlings were reported in the area.</p>
