Project Summary

Pest management research is often conducted on a single pest or pathogen. But in most cases, soybean plants are attack simultaneously by numerous organisms in the field over the course of a growing season. There are examples known where two or more different crop pests or pathogens affect the biology and the damage caused by each other and where the activities of one pest will affect the management tactics for the other pest.

The overall goal of this project is to provide soybean growers with the information necessary to successfully manage multiple pests in their fields. The research team will conduct studies to solve real-world pest problems and then translate the results into management recommendations for the Iowa soybean grower.

Project Objectives

1. Do soybean aphids reduce the effectiveness of all sources
2. Do fields managed for soybean aphids still show increased SCN reproduction?
3. How should soybean aphid management be adapted to concurrently manage SCN populations.
4. Why do aphids increase nematode performance?
