Welcome to the Northern Plains IPM Guide!
The soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), is a significant insect pest of soybean in the north-central region of the U.S., causing estimated yield losses of at least $2.4 billion annually if left untreated. Read more about soybean aphid

This guide is intended to provide current effective management options for insect and other arthropod pests and for plant pathogens affecting all major field crops grown in North Dakota, South Dakota, Minnesota, Nebraska, Iowa and Kansas. Chemical and non-chemical control practices, when available, are described in detail for individual pests and pathogens. These practices include cultural and biological control options, and host plant resistance. By including alternatives to pesticides, we hope to create a ready reference of management strategies growers will consider when faced with a pest problem.
This effort is coordinated by Drs. Kelley Tilmon and Buyung Hadi. They are glad to receive questions and comments regarding this guide.
