It's mid-September and the tenth episode of Season 9! Erin provides a brief update on the newest soybean pest in Iowa - soybean gall midge. Activity has slowed drastically since the last episode and is coordinated with quickly maturing fields in western Iowa. Matt traveled to Brazil for a soybean congress and gave some updates on new invasive in this large soybean-growing country.
Today, Matt is back from vacation and talks with Erin about the latest insect activity in Iowa. Soybean aphids can be found in northern Iowa, but at very low numbers. Japanese beetles are feeding in corn and soybean in central counties, and a mixture of caterpillars are feeding in soybean.
