Organizational Unit

Plant Pathology and Microbiology

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 objective of this study was to assess the comparative effect on warm and cold germination of seed from five different inbred maize cultivars following Defol 750 (sodium chlorate) application at approximately 50% moisture content. The trial was conducted in 2016 at the Syngenta Seed Production Research Farm in Waterloo, Nebraska using a randomized complete block consisting of three locations with a factorial arrangement of sodium chlorate treatment and an untreated control. Sodium chlorate application improved the cold germination of one variety by a score of 17.5 and showed significant effect of desiccation on the cold germination on the tested inbreds (p0.05). The application of sodium chlorate also resulted in a significant effect on an inbred seed size interaction (p
