Soybean aphid populations remain low but first generation bean leaf beetles are out i some areas this week. Spider mites are still the primary problem, and we encourage scouting to protect yield.
Most of the state is approaching the seed fill stage (R5), indicating the end of profitable yield returns with an insecticide application. Watch a short video about spider mite management here: http://bit.ly/NdDj6c
The 2013 season of podcasts begins with a short recap of pest activity in Iowa.
This week, Erin Hodgson talks about confirming soybean aphid in Iowa, Minnesota, Michigan and Wisconsin.
Matt and Erin kick off the 2015 growing season with a summary of soybean planting progress in Iowa and predictions for soybean aphids this year. Also, they talk about recent publications on soybean seed treatments.
Today, Matt and Erin talk about potential soybean seedling pests, including bean leaf beetle, slugs and black cutworm. They also shared some details about Pollinator Fest, a special event to promote pollinators on June 20. Find out more here: http://www.reimangardens.com/event/pollinator-fest/.
Today, Matt and Erin invite grad student, Mike Dunbar, to share his recent experience of true armyworm in a cornfield with a rye cover crop. Read more about true armyworms here: http://bit.ly/1QawkYf. Also, we have a brief discussion on slug management. Read more about slugs here: http://bit.ly/1HcZTUi.
Today, Matt and Erin recap current soybean planting progress in Iowa. They also talk about recent armyworm activity in soybean and considerations for management. Finally, the podcast wraps up with a quick summary of a symposium organized for neonicotinoid seed treatments in field crops from last week.
“Apres moi, le deluge” is legendary quote from King Louis XV of France. Allegedly he said this with regard to what would happen to France after his death; After me, the flood. 15 years after a reign that saw the loss of wars, territory etc., the French Revolution broke out.
Today on the soybean aphid podcast, we turn this title around (after the rains, us) to discuss the consequences of the June rains that have dropped as much as 6 inches in a 72 hour period. Unlike the terrible decisions of King Louis, these rains can have a benefit to farms by limiting the impact of some pests, especially those in the soil. However, the rains have made it difficult to get into fields for herbicide applications.
We discuss the rain, its impact on pests, and the upcoming Pollinator Festival at Rieman Gardens in Ames this Saturday June, 20.
Also, help us come up with a new name for out podcast. Send your suggestions to Matt at oneal at iastate.edu and/or Erin at ewh at iastate.edu.
Matt is on vacation, but the show must go on! Erin talks about recent soybean pest activity in Iowa, including the beginning of soybean aphid sightings in northern counties. Also, some are seeing green cloverworm starting to defoliate plants. Both are at sub-economic levels but continue to scout to make timely treatment decisions in 2015.
