Soybean Cyst Nematode- Identification and Extraction Techniques

Abstract

<p>A major factor limiting soybean production in Iowa is parasitism by the soybean cyst nematode, Heterodera glycines. Soybean cyst nematode was identified in Clinton and Scott Counties for the first time in 1995 and is now known to be present in 69 Iowa counties. It is very likely that the nematode is present in many other counties as well, but the nonspecific nature of the aboveground symptoms of soybean cyst nematode damage makes early identification or diagnosis of infestations difficult.</p>
