Description: 

Don't drought this episode was a good one. Matt shares an update on the Iowa drought and encourages people to use the U.S. Drought Monitor as a tool to measure landscape moisture levels. Matt and Erin transition and talk about pest activity around the state, starting with twospotted spider mite. Erin wrote a recent ICM News article that talks about scouting and managing this pest that favors hot and dry conditions. Spider mites can be first detected around field perimeters and then eventually infest the field interior. Discoloration, webbing and stunted plants are often the result of heavy spider mite feeding. Erin mentioned a new miticide, AgriMek, that has promise for suppressing mites in corn and soybean; find the label here. The conversation switched gears to talk about some corn silk clipping pests, like Japanese beetle and corn rootworm adults. Scouting to determine pest densities and potential interference with pollination is important. Learn more about Japanese beetle ID, scouting and management with an ICM News article

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.
