Weeds Hosting the Soybean Cyst Nematode (Heterodera glycines Ichinohe): Management Implications in Agroecological Systems

The soybean cyst nematode (SCN; Heterodera glycines Ichinohe) is a major soybean-yield-limiting soil-borne pathogen, especially in the Midwestern US. Weed management recommended for SCN integrated management, since some weed species have been reported to be hosts SCN. increase occurrence of resistance herbicides complicates and may further direct ecological–evolutionary (eco–evo) feedbacks plant–pathogen complexes, including interactions between host plants In this review, we summarize US outline potential weed–SCN interactions. Plants from 23 families SCN, with Fabaceae most species. Out 116 weeds hosts, 14 known herbicide-resistant biotypes 8 herbicide sites action. Factors influencing ability are environmental edaphic conditions, initial inoculum, population levels, variations susceptibility within population. association on relatively little fitness cost incurred by latter decrease competitive crop reproduction when present, feeding back into probability selecting biotypes. Therefore, proper should focus pest (IPM) strategies prevent eco–evo cropping system.
