Soybean Pest Podcast
The 2013 season of podcasts begins with a short recap of pest activity in Iowa.
Most of the state is approaching the seed fill stage (R5), indicating the end of profitable yield returns with an insecticide application. Watch a short video about spider mite management here: http://bit.ly/NdDj6c
Soybean aphid populations remain low but first generation bean leaf beetles are out i some areas this week. Spider mites are still the primary problem, and we encourage scouting to protect yield.
Although soybean aphid has been a relatively low threat this year, drought conditions have been a perfect storm for spider mites. We encourage people to scout fields now to fully protect yield.
Drought conditions continue for all of Iowa, setting the stage for spider mite outbreaks. Drs. O'Neal and Hodgson discuss the challenges of managing this pest.

Its Friday the 13th and farmers have much to worry about. But despite the record breaking temperatures and drought, there is some good news. We discuss the lack of soybean aphids throughout most of Iowa. However, there are other insect pests that growers should be scouting, including japanese beetles and spider mites. For more info about insects this summer, see Dr. Hodgson's blog (http://iowabuglife.blogspot.com).
Hot weather isn't favorable for soybean aphid, so numbers are still down. But spider mites and other pests thrive in these conditions.
As we wait for soybean aphids to arrive, we discuss how the early and large outbreak of Japanese beetles in central Iowa may harm crop production. Dr. Hodgson discusses some options for preventing the beetles from clipping corn silk, a significant form of damage caused by these pests.

June is often a quiet month for insect pests but not this year as the Japanese beetle has emerged 2 to 3 weeks earlier then usual. So even though soybean aphids are uncommon right now, farmers may want to scout for this pest. We discuss what to look for and what the impact could be. To meet with Dr. Hodgson, consider joining her at the Crop Management Clinic (11-12 July) at FEEL. Visit this site for more information http://www.aep.iastate.edu/feel/cmc.html
Drs. Hodgson and O'Neal return with weekly updates on the insect pests attacking soybeans. This week we discuss the first reports of soybean aphids in Iowa, the growing risk for spider mite outbreaks, and an alarming change in the emergence of Japanese beetles.
