Soybean aphids found

Over the weekend, Brian Lang (ISU field agronomist) found soybean aphids on V1 plants. He samples weekly in small plots and commercial fields in NE Iowa. He wasn't surprised when finding them, as he typically sees aphids the first week of June.

Also, high numbers of winged small grain aphids are being trapped in the suction trapping network this year. This could potentially a problem in corn later in the season.
