The Department of Plant Pathology and Microbiology and the Department of Entomology officially merged as of September 1, 2022. The new department is known as the Department of Plant Pathology, Entomology, and Microbiology (PPEM). The overall mission of the Department is to benefit society through research, teaching, and extension activities that improve pest management and prevent disease. Collectively, the Department consists of about 100 faculty, staff, and students who are engaged in research, teaching, and extension activities that are central to the mission of the College of Agriculture and Life Sciences. The Department possesses state-of-the-art research and teaching facilities in the Advanced Research and Teaching Building and in Science II. In addition, research and extension activities are performed off-campus at the Field Extension Education Laboratory, the Horticulture Station, the Agriculture Engineering/Agronomy Farm, and several Research and Demonstration Farms located around the state. Furthermore, the Department houses the Plant and Insect Diagnostic Clinic, the Iowa Soybean Research Center, the Insect Zoo, and BugGuide. Several USDA-ARS scientists are also affiliated with the Department.

Abstract

The soybean cyst nematode, Heterodera glycines Ichinohe, is considered the most damaging pathogen of soybean (Glycine max (L.) Merr.) in the United States and Canada (6). This nematode also causes considerable yield loss in many other soybeanproducing countries in the world. Heterodera glycines was first discovered in the United States in New Hanover County, North Carolina in 1954 (5) and is believed to have been introduced from Asia (3). In 1987, the nematode was discovered in Kent County, Ontario (1). At various times since these initial discoveries, maps were created of the counties in the United States and Canada that were known to be infested with the nematode.
