Soybean Pest Podcast

Matt and Erin took a short podcasting break but are back to summarize late season soybean pest activity. Erin talks about a slight resurgence of soybean aphid populations in northern Iowa. Read more about treating at full seed set in a recent ICM Blog. Erin also recommends scouting in late August/early September for second-generation bean leaf beetles, as feeding injury to pods and seeds could be significant. Matt has noticed perhaps early field senescence in some commercial fields in Iowa. He also took a trip to Mississippi to see soybean production and learn more about pollinator protection. This podcast also features a F.I.T.!

It seems like a long time since the last episode and that's because it was! Matt and Erin are back to talk about pest updates in Iowa. Drought stress throughout much of the state has been ideal for twospotted spider mite. Erin reports Some injury has been observed in corn and soybean this summer. Treatments are going on now throughout some southern Iowa counties. In addition, soybean aphid continues to be an erratic pest. Some populations are building up in northern Iowa counties, but most fields are not reaching the economic threshold in July. Matt elaborates about high numbers of Japanese beetle and they talk about the use of pheromone traps as a management tool. Finally, Matt talks about a new Science research paper that has inconsistent data on the effect of neonicotinoid seed treatments on wild and managed bees in Europe.

Today, Erin is without her podcasting bestie, Matt. She summarizes the activity of a few field crop pests in Iowa. First, she mentions Japanese beetle is active in soybean now and will move to corn with the emergence of silks. There are also European corn borer egg masses and small larvae in non-Bt corn now. You can access a free publication to learn more about scouting and management of ECB. Erin also gives an update on thistle caterpillar and soybean aphid from the last episode - both pests are still active right now. Finally, she highlights potato leafhopper as an occasional pest of soybean and alfalfa. You can register for some upcoming demonstration events at FEEL for July 12 (Diagnostic Clinic) and July 13 (Management Clinic) right here.

In this mid-June episode, Matt and Erin start off by summarizing current soybean aphid activity around the state of Iowa. Populations are showing up over much of northern Iowa the last two weeks. Some fields have approached infestations ranging from 10-50%, although the density per plant remains low. Under ideal conditions, these populations could exceed the economic threshold in a few weeks. Brian Lang also found an aphid mummy, which is also early compared to most summers. Erin talked about a new publication for European corn borer that is available at the ISU Extension Bookstore. The 12-page pub reviews identification, life cycle, plant damage, scouting and treatment recommendations for this devastating pest. In their new segment, Matt talks semantics about how to spell one of the most widely recognized insects in the world.

In this episode, Matt and Erin start off with talking about the hot weather in Ames. A local rain shower will help lawns and crops. Erin shared some updates on soybean aphid in Iowa. A few more reports are showing up from the lab as they visit various research farms. The percent infested plants is higher than in the past few years, so scouting in highly encouraged this summer. Both have noted aphids around the yard and on campus this month, too. Matt wants to try out a new segment called F.I.T. (fun insect trivia). He asked me about how the malaise trap was named and Erin was kinda right. Erin also had a F.I.T. about determining the sex of Japanese beetle. It wasn't nearly as interesting as Matt's story and maybe not even that important to know. Erin also noted Japanese beetles are emerging in southern Iowa and corn rootworm egg hatch is peaking around Iowa this week. If you live in north-central Iowa, plan to attend a field day at the ISU Northern Farm near Kanawha.
