Season: 
13
Episode: 
6
Description: 

It's a low-key episode that features new intro and outro-music and a new pest noted in our round up (grasshoppers).

Erin's had a long week talking about corn rootworms. We recap the current insect species occuring in soybean fields (grasshoppers, Japanese beetles, soybean aphids, a mix of caterpillars). Some pests are no longer present on the plants as the second generation is developing as immature stages in the soil. These are gall midges and bean leaf beetles. Matt tries to bring her spirits up with two trivia question. The first is a bit silly, noting the music videos on youtube that have been viewed over one billion times. The second question is a FIT that Erin gets immediately. Erin's on a roll.

see you next week, and as always, consider scouting your fields.

(S1:E12): A discussion with Mary Gardiner about lady beetles

09/18/2009

Dr. Mary Gardiner, assistant professor at the Ohio State University, visited ISU and gave a seminar about her research on the ladybeetles.   Ladybeetles can play a positive role by feeding on pest like the soybean aphid.  Mary's research is focused on the exotic multi-colored asian ladybeetle. This species is a voracious predator of soybean aphids, but is also a pest in our homes and to grape growers.  Mary is documenting the role landscape plays in the establishment of this species as part of her Buckeye Lady Beetle Blitz.  To learn more about Mary's work visit http://ladybeetles.osu.edu/default.asp 

(S1:E11): Corn Aphids: is this the next new pest for Iowa farmers?

09/11/2009

Matt O'Neal talks with Amy Asmus of Asmus Farm Supply to discuss outbreaks of aphids in cornfields around north-central Iowa.  The two discuss what species of aphids are in corn and what impact they may have. Be prepared for more questions than answers as the scientist and crop consultant compare notes about this problem. For a more complete description of the aphids see Dr. Erin Hodgson's article in the Integrated Crop Management Newsletter (www.extension.iastate.edu/CropNews/2009/0807hodgson.htm)

(S1:E10): An aphid is an aphid is an aphid

08/25/2009

Its mid-August and soybean aphids are starting to look white and small (yes, even smaller). Do they count? Are aphid populations still increasing? Why? Erin and Matt answer these questions and more.

(S1:E9): Attack of the winged aphids

08/17/2009

Erin and Matt discuss the recent increase in aphid populations including winged aphids that are moving from field to field.  We discuss what growers should consider when applying insecticide to soybeans when seeds are developing. We summarize a recent Integrated Crop Management newsletter articles on late season management of soybean aphids.

(S1:E8): Spotty aphid outbreaks continue

08/11/2009

Erin and Matt report on observations on aphid populations around Iowa from the week of August 3-7.  We discuss the continued production of winged aphids, their capture in the suction trap network (visit it at www.ncipm.org/traps/), and the changing appearance of aphids in the field (winged, wingless and white dwarves).  If you have questions, please post them at www.soybeanaphid.info.

(S1:E7): Considering insecticides for managing aphids

08/07/2009

For the past 5 years, we have evaluated insecticides for managing soybean aphids. The most recent report can be found at our website www.soybeanaphid.info. After applying insecticides as part of our 2009 insecticide evaluation, Erin and I discuss some issues to consider when selecting an insecticide

(S1:E6): Update on Iowa bee rule

08/03/2009

In this extra podcast, Matt O'Neal discusses a recent change to the Iowa bee rule with Betsy Buffington. Betsy works for The Pesticide Applicator Training Program at Iowa State University. She has created a publication about the bee rule, which can be found at the Iowa State University Extension publication office as PAT 47. Visit https://www.extension.iastate.edu/store/ for more information.

(S1:E5): Soybean aphid populations' build

08/03/2009

For the week of August 3, 2009, Drs. Hodgson and O'Neal discuss scouting reports from the previous week indicating increases in aphid populations.   In our longest podcast to date we discuss several issues growers should consider with regard to spraying insecticide for soybean aphids, including the potential for spider mite outbreaks.

(S1:E4): Slow growing aphid populations

07/27/2009

For the week of July 27, 2009, Drs. Erin Hodgson and Matt O'Neal review reports and data on soybean aphid populations from Iowa and the midwest. Although large populations can be found, many growers are reporting low populations with less than 50% of the plants infested with aphids. Also, Erin discusses reports of soybean defoliation by insect pests that are not aphids.

(S1:E3): Aphids on the move in Iowa

07/20/2009

For the week of July 20, 2009, Drs. Erin Hodgson and Matt O'Neal discuss the state of aphid populations in Iowa.  Aphids are now well established in many fields but at low populations.  We discuss factors that can contribute to the likelihood of an outbreak.  Also, Erin and Matt make a joke about aphid perspiration.
