Abstract

Brian Lang, extension field specialists in crops, reported on July 23 that soybean aphid populations had dramatically increased in some Winneshiek County fields. He noted that some plants hosted 5,000-10,000 aphids and these densities could be found throughout the field. Insecticides were being sprayed to control soybean aphids and several chemicals were giving 95 percent control. Herb Eichenseer, research scientist at Pioneer Hi-Bred International, reported small populations of soybean aphids near Johnston on July 18.
