Breaking out, in a corn sweat.

Description: 

The heat is making field work challenging and podcasting an attractive alternative.

Erin covers a lot of ground, recapping reports of increasing (though sub-economic) soybean aphid populations, rootworm injury and new additions to the insects found in corn and soybean fields, including skipper sightings in soybeans (https://crops.extension.iastate.edu/blog/erin-hodgson/have-you-spotted-s...).

The hot and dry conditions in the western half of the state is making it challnging for corn and soybeans. We've seen this issue in the past, and this article reviews how to address spider mites that may be exacerbated by these weather conditions: https://crops.extension.iastate.edu/cropnews/2018/08/you-%E2%80%9Cmite%E2%80%9D-want-scout-drought-stressed-crops

Matt highlights some observations from a cannabis farm, in which a Eurasian Hemp Borer was observed on several plants.  A summary of this pests biology, ecology and management can be found in this factsheet from the Colorado State University: https://webdoc.agsci.colostate.edu/hempinsects/PDFs/Eurasian%20hemp%20bo...(1).pdf

On 23 July, 2020, Matt is speaking at a webinar sponsored by the Liberty Prairie Foundation.  He wil talk about how the prairie strips practive in the Conservation Reserve Program (CP-43) can conserve pollinators on farm land. Details about this webinar and others hosted by the Liberty Prairie Foundation can be found here: http://libertyprairie.org/calendar/. Please feel free to join the webinar.

See you next week and stay safe.

Whose gonna win the race- soybean plants or aphids?

Soybean Pest Podcast

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.

Post-Derecho report, part 1 (also soybean aphid population are increaseing)

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.

Matt tries to get our minds off of the Derecho, drought and rising soybean aphid populations with a Fun (?) Insect Trivia question.

Stay safe.

Courage,
Matt
