3 Pest Management 11. IPM 101 (1.0 PM) Meaghan Anderson, Extension field agronomist, Iowa State University Extension and Outreach, Iowa City, IA; Laura Jesse Iles, director, and Ed Zaworski, diagnostician, Plant and Insect Diagnostic Clinic, Iowa State University, Join the presenters for a fun, fast-paced quiz session on important weed, insect, and disease topics from 2017 and coming up for 2018! This session will move quickly, so be prepared to test your skills and win a prize for the most pest knowledge! 12. Genetically modified crops: Marvel or malady? (1.0 PM) Peter Goldsbrough, professor, Botany and Plant Pathology, Purdue University, West Lafayette, IN Twenty years after their introduction, GMOs remain one of the most controversial technologies used in agriculture. New gene editing techniques provide even more methods to modify plants and animals. Will these new technologies deliver on their promise or just deliver another dose of controversy? Session C - Wednesday, 11:00 AM - 11:50 AM 13. The Iowa Pest Resistance Management Plan: A community based approach to address pest resistance in Iowa (1.0 PM) Evan Sivesind, program manager, Entomology, Iowa State University, The Iowa Pest Resistance Management Plan is a community based effort to address the increasing threat of pest resistance in Iowa. This session will present the history of the plan, an update on pilot projects being developed around the state, and opportunities for involvement. Session N - Thursday, 3:00 PM - 3:50 PM 14. Back to the basics: Integrating weed biology into weed management plans (1.0 PM) Jared Goplen, Extension Educator, Crops, University of Minnesota Extension, Morris, MN Herbicide-resistant giant ragweed and waterhemp continue to spread across the Midwestern U.S., making control with herbicides more difficult. This presentation will discuss specifics of how weed management plans can be improved by incorporating knowledge of weed biology to manage herbicide-resistant weeds. 15. Dicamba injury: Crop and liability insurance perspectives (1.0 PM) Ray Massey, Extension professor, Agricultural Economics, University of Missouri, Columbia, MO Herbicide injury risk management requires active oversight of crop or liability insurance policies. Federal crop insurance does not cover losses due to pesticide injury but has made provisions for protecting farmers' Actual Production History (APH). Various provisions in liability insurance contracts may affect whether or not insurance companies pay for losses due to herbicide injury. 16. Dicamba: Past, present, and future (1.0 PM) Bob Hartzler, professor and Extension weed scientist, Agronomy, Iowa State University, The first year of dicamba use in dicamba resistant soybean resulted in unprecedented levels of off-target injury. The properties of dicamba, factors influencing off-target movement, and how to minimize risks in the future will be discussed Integrated Crop Management Conference November 29 and 30, 2017 Ames, Iowa page 3

4 17. Weed management update for 2018 and beyond: The more things change... (1.0 PM) Micheal Owen, University Professor and Extension weed scientist, Agronomy, Iowa State University, The presentation will focus on recent changes in weed management options and possible issues in 2018 and beyond. The herbicide-resistant weed situation in Iowa will be described. The use of herbicide-tolerant crop cultivars will be discussed. Session A - Wednesday, 9:00 AM - 9:50 AM 18. Rootworm behavior and resistance in Bt cornfields (1.0 PM) Joseph Spencer, Principal Research Scientist and Research Program Leader in Insect Behavior, Illinois Natural History Survey, University of Illinois, Champaign, IL Bt corn was supposed to be a durable solution to corn rootworm problems. Unfortunately, Bt resistance among corn rootworms now limits the future utility of Bt hybrids for their management. Analyses of beetle behavior in non-bt refuges designed to delay resistance suggest that our best laid plans likely promoted resistance evolution. 19. Soybean aphid bites back: Update on pyrethroid resistance (1.0 PM) Erin Hodgson, associate professor and Extension entomologist, Entomology, Iowa State University, Soybean aphid is an erratic pest in Iowa, and confirmed pyrethroid resistance in the Midwest has made pest management more complicated. This presentation will provide an update on resistance and guidelines for crop protection. 20. Iowa monarch conservation, pest management and crop production (1.0 PM) Steve Bradbury, professor, Natural Resource Ecology and Management, Iowa State University, Ames, IA The eastern population of the monarch butterfly has declined by 80% over the past two decades and may be listed as a threatened species under the Endangered Species Act. To increase monarch populations to a level that would reduce the probability of extinction, establishment of milkweed and nectar plants in rural roadsides; marginal crop land; portions of existing CRP land, pastures and grassland; and grassy areas bordering crop fields is needed. The presentation will describe the science-based Iowa Monarch Conservation Consortium s strategy that integrates crop production, pest management and monarch habitat needs. Session C - Wednesday, 11:00 AM - 11:50 AM 21. Where do we stand with soybean cyst nematode, resistance, and seed treatments? (1.0 PM) Gregory Tylka, professor, Plant Pathology and Microbiology, Iowa State University, The soybean cyst nematode (SCN) continues to be rated the most-damaging soybean pathogen in the U.S. and Canada. Management of SCN with resistant varieties is becoming less and less effective. Seed treatments are available to use for added protection. We'll discuss the current situation with SCN in this session using research data collected from throughout Iowa Integrated Crop Management Conference November 29 and 30, 2017 Ames, Iowa page 4
