Description: 

Erin and Matt are back after a week off of podcasting to discuss a remarkable sitatution in Iowa. Soybean plants are developing faster than normal, 1-2 weeks ahead of schedule.  Aphid populations are increasing. Are the plants going to out grow the aphids? So what should a farmer do? Erin and Matt discuss the pros and cons of a foliar insecticide application.

Erin discusses some insects attacking the other crop grown in Iowa (hint: its corn). Corn earworms are causing injury due to the second summer migration.

Its a drought in the wester half of Iowa and the duo discuss how that may or may not be the cause of more frequent observations of spider mites.

Finally, Matt has a short FIT-ish question for Erin that she gets right! That's two in a row.

Description: 

It was a terrible, horrible, no good very bad week in central Iowa.  Erin and I give a summary of the Derecho's impact. We give a brief shout-out to ISU Extension, and Meaghan Anderson's summary of the damage to corn (https://mailchi.mp/4d564a6886f2/aixk6z6qw1-5248549?e=89e709107e). Consider joining Meaghan's newsletter: https://iastate.us10.list-manage.com/subscribe?u=08f91c67b14ea5bf5a26ba3...

We also talk about the recent increase in soybean aphid populations and the occurence of sub-populations that are resistant to pyrethroids. This may result in soybean aphids remaining in fields that were sprayed with insecticide.

No fun insect trivia this week. It was enough just to clear the yard, fields, etc and get the power back on.

We're Back! And we are hot and dry

Description: 

Season 12 of the soybean pest podcast starts off with a bang, a hot, dry bang.  The midwestern drought is affecting all of us, even the 6-legged.

Check the UNL drought monitor for the current status (hint, its bleak: https://droughtmonitor.unl.edu/CurrentMap/StateDroughtMonitor.aspx?IA)

We talk spider mites, cause its hot and dry.

Erin discusses the remarkable pests outbreaks occurring in alfalfa, exacerbated by a mild winter and hot, dry spring.

Matt turns our attention to Japanese beetles (JB), and the duo speculate about the impact weather has on their abundance. Erin notes a trend of JB larvae in the interior of cropfields, not just the edges. (https://crops.extension.iastate.edu/cropnews/2021/06/japanese-beetle-adu...)

Erin notes the first appearance of soybean gall midges in northeaster Iowa. Matt notes some progress in detecting insecticide resistant aphids.

Rootworms are also discussed as we note egg hatch, signaled with the appearance of lightening bugs.

Finally, Erin takes might to school with reports of the Hackberry emperor. Its a pretty butterfly, definitely not a thistle caterpillar and notorious for being a cheater (https://crops.extension.iastate.edu/blog/erin-hodgson/have-you-seen-chea...)

To wrap up- Erin gives updates on her live events and we note the 26 June is pollinator fest at Reiman gardens (https://www.reimangardens.com/event/pollinator-fest-7/)

Also, did we mention its hot and dry?

Stay tuned for weekly updates now that the field season is in full gear.
