In the first episode of 2019, Matt and Erin wax philosophical about IPM. The conversation wanders around profitability, durability, and sustainability of corn and soybean farming in Iowa and beyond. Is now the time to think about re-establishing IPM into farm as new technologies emerge?
Matt and Erin are back and starting Season 10! Erin kicks off the episode by summarizing current pest activity for 2019. It's been a cool, wet spring and delayed planting will influence early-season pest activity. Specific updates:
- Bean leaf beetle winter mortality was high.
- Seedcorn maggots are flying.
- Alfalfa weevils are active.
- Expected corn cutting dates from black cutworm are approaching.
- Soybean egg hatch is happening, most likely in northern Iowa, where most of the buckthorn is located.
Matt talked about a new F.I.T. (fun insect trivia), where he highlights the mosquito trapping network at ISU. Dr. Ryan Smith coordinated a mosquito and tick surveillance program to learn more about activity and disease incidence around the state every summer. Learn more about his historical data on his website.
Matt also had an opportunity to podcast with group of Iowa Youth who entered an NPR challenge. You can hear the episode where they talk about using insects for food here later this summer!
After a break, Matt and Erin get together for episode 3 in 2019. Erin mentioned a flash drought is expected this week if high temperatures continue throughout Iowa. This could have implications for pest management - slowing down soybean aphid but perhaps accelerating twospotted spider mite. Erin also highlights current pest activity in field crops, including corn rootworm and Japanese beetle. But they spent some time talking about the newest pest in Iowa, soybean gall midge. So many unanswered questions, but it appears this will be an economic soybean pest. Matt comes back to an older podcast episode where they reviewed the cancellation of sulfoxaflor insecticide. It was recently registered (again) by the EPA and will be labeled in soybean. This insecticide offers an alternative mode of action for soybean aphid. Finally, Matt brings up a F.I.T. that is about isopods.
Today, Matt and Erin recap insect activity around Iowa. They also discuss implications of the dry weather for 2019.
Matt and Erin took a 9-month break, but they promised to post more regular podcasts this year with Season 11. Erin provides a brief summary of statewide pest activity, including bean leaf beetle, seedcorn maggot, and alfalfa weevils. The first painted lady butterflies were also noted in Iowa over the weekend. Lastly, Matt poses the latest F.I.T. and talks about an invasive insect into North America.
Matt and Erin are back in the swing of podcasting after a long winter. But the pandemic means they can record the episode in their sweatpants! Matt provides an update on brown marmorated stink bug, an invasive species on the rise in Iowa and Japanese beetle activity. Erin gives a short recap of recent pest conditions in soybean, noting wireworms. Matt wraps up the conversation with a newly-designed F.I.T.
Our extension program is led by Dr. Erin Hodgson, and Dr. O’Neal and many lab members also participate in programs throughout the year. We are focused on delivering research-based information to a variety of clientele. Our group serves farmers, crop consultants, agricultural professionals and other university/extension personnel. Most of our programs are within the state of Iowa, but we travel throughout the Midwest to deliver content. Read more about Extension
