CropsTV is entering week 9, however, do not let this hold you back from registering. There are 3 live episodes this week and another 3 live episodes to finish out CropsTV programming next week. While there is only 6 live episodes left, you can still watch all 45 episodes on-demand through February. Learn more and register here today. You can view the full 10-week program here, but read on to check out a quick preview of our week six presentations.
Tuesday, January 26 at 9 to 10 a.m.
- Corn rootworm management update
Erin Hodgson, professor and extension entomologist, Entomology, Iowa State University, Ames, IA
During the past decade, there are been a number of challenges in the management of corn rootworm, including the development of resistance, which has arisen in large part because of prophylactic management. This presentation will review scouting tips and economic thresholds, and focus on research-based management strategies for more sustainable corn rootworm suppression.
Wednesday, January 27 at 9 to 10 a.m.
- Making sense of cover crop management research
Mark Licht, assistant professor and extension cropping systems specialist, Agronomy, Iowa State University, Ames, IA
This topic will use recent cover crop research to hone in on best management practices for cover crops adoption in Iowa. The focus will be on research results from cover crops seeding methods, seeding rate and termination timing; starter N and strip-tillage ahead of corn; and interseeding cover crops into vegetative stage corn.
Thursday, January 28 at 9 to 10 a.m.
- Drought tolerance in corn hybrids is affected by timing of drought stress initiation
Jeff Coulter, professor and extension specialist of corn-based cropping systems, Agronomy and Plant Genetics, University of Minnesota, St Paul, MN
In the upper Midwest, moderate drought stress often occurs during the mid- to late reproductive stages of corn, and sometimes occurs during pollination. The availability of drought-tolerant hybrids, increasing corn acres under irrigation, and variable-rate technology provide many growers with new opportunities to mitigate drought stress in corn. This session will help participants better understand corn hybrid response to moderate drought stress, enabling improved agronomic decisions when dry growing conditions are anticipated or when irrigation water is in limited supply.
