Most of you probably have seen the spiral-bound field guides produced by Iowa State University Extension. They have been very popular resources for farmers and ag professionals, and convenient for management in corn and soybean. Now there is a new full-size publication that is focused on insects available at the ISU Extension Online Store (CSI 0014) for $5! The guide can also be viewed online.
In January 2012, Iowa State University and the Iowa Soybean Association released a collaborative publication, Field Crop Insects, the latest in a series of practical and valuable reference tools for farmers. This publication is a comprehensive resource to help with identification and management of common corn and soybean pests. The 74-page publication is filled with vivid, full-color images and descriptions of insect pests and the damage they cause to soybean and corn. Management options are provided as well as Web addresses for access to more detailed insect control recommendations.
