This collaborative research program targets disease and insect stresses that reduce soybean yields. The researchers will work together to find strong traits of resistance, mechanisms of pest management, efficient means of disease prevention, and to develop economical and environmental sustainable disease and pest recommendations. The various objectives include: • Monitoring sentinel plots for soybean rust and providing field data to the ipmPIPE program; • Examining how soybean aphids vector Soybean Mosaic Virus in aphid-resistant soybean lines; • Assist in developing an on-line Northern Plains IPM Guide that provides information on pest management recommendations; • Develop novel bioassays for soybean pathogens and resistance screening; • Continue to develop a comprehensive research and extension educational program on the biology and management of soybean cyst nematode; • Deliver a broad extension program targeting critical soybean pest management issues through on-farm-demonstrations, publications and innovative programming; • Develop aphid thresholds appropriate for aphid-resistant cultivars; • Examine the efficacy of insecticidal seed treatments for aphid control in regular and resistant soybean varieties; • Develop outreach materials based on the release and monitoring program for the aphid parasitoid, Binodoxys communis; • Screening soybean germplasm and varieties for Phytophthora root and stem rot and Northern stem canker; and • Continue identify and map genes for soybean aphid resistance.
