​The integrated pest management (IPM) approach to pest management requires consideration of several factors: 1) knowledge of the plant; 2) knowledge of potential pest species; and 3) knowledge of action options. Key early season pests in Kansas cotton are thrips and fleahoppers, which can delay crop development (thrips) and delay fruit set (fleahoppers). Pests during the midseason through “cut-out” include tarnished plant bugs, bollworms (possibly), and stinkbugs, which can cause losses in yield and quality. Growers must scout frequently, regularly, and thoroughly to be able to detect a problem and have time to act on it in a timely manner. It’s important to avoid delays to crop development and fruit set, because they can ultimately result in delays in harvest (something Kansas growers can’t afford). Timeliness in actions during the season can help timeliness at harvest-time. 

About the Presenter

Rex FriesenRex Friesen was born in Bakersfield, California, and grew up in Shafter, a small farm town in the San Joaquin Valley. He graduated from California State University at Fresno in 1983 with a BA in biology and from the University of California at Riverside in 1991 with a PhD in population biology. His dissertation research was on the integration of agronomic and pest management practices to reduce pest impact in cotton. Friesen worked as a postdoctorate foreign exploration research entomologist for the USDA Department of Forestry from 1991 to 1995 and was assigned to the problem of biological control of a major weed species in Hawaii. From 1995 to 2000, he worked for the Texas A&M Extension Service as an integrated pest management agent in Fort Stockton and the surrounding area, primarily assisting growers in pest management in cotton and alfalfa. In 2000, he moved to Oxford, Kansas, to supervise the Southern Kansas Cotton Growers (SKCG) Cooperative field scouting program, which he did for several years. He continues to serve as the SKCG crop consultant and public relations representative, providing information for growers on “most things cotton,” including production, harvest, ginning, and other pertinent topics.
