Drs. Matt O'Neal and Erin Hodgson are back with their weekly podcast regarding the soybean aphid and other insect pests of soybeans. In this brief (~3min) episode we talk about the state of soybean aphids in Iowa and the midwest with a quick review of efforts to monitor aphid migration to soybeans. Please email us with your questions (firstname.lastname@example.org or email@example.com)
In this episode Drs. O'Neal and Hodgson discuss the low populations of soybean aphids in Iowa. Dr. Hodgson highlights upcoming meetings and workshops to learn more about soybean production and pest management.
Drs. O'Neal and Hodgson give a quick update on the status of soybean aphid populations in Iowa. They also review the other insect pests that may be out this time of year feeding on soybean leaves.
Still very few aphids in the soybean fields of Iowa. Drs. O'Neal and Hodgson give an update and discuss the likelihood of a soybean aphid outbreak later this summer. Also, Dr. Hodgson gives us an update of events where she will discuss recent research and new tools for pest management in soybeans.
Aphids are still hard to find, but that doesn't mean that Matt and Erin can't find something to talk about. We discuss spraying insecticides based on a calendar date as opposed to spraying insecticide based on need (i.e. aphids populations above a threshold).
Winged aphids are still on the move in Iowa, although most fields still remain well below treatment levels. Neighboring states have notable aphids, so scouting should still continue.
Soybean aphids are picking up activity throughout Iowa; however, populations are still very patchy. Also consider other defoliators in soybean right now that might compound stress during pod set.
Drs. Matt O'Neal and Erin Hodgson discuss current soybean aphid activity around Iowa and the region. Numbers are remaining low with some regions declining in density. They also discuss upcoming field tours (available at www.aep.iastate.edu).
Hot weather isn't favorable for soybean aphid, so numbers are still down. But spider mites and other pests thrive in these conditions.
Dr. Hodgson and O'Neal talk about the preharvest intervals for those soybean growers considering an insecticide late in the season.
