Non-host weed species of Heterodera glycines

Studies have been carried out in Iowa (US) on the ability of the soybean nematode, Heterodera glycines (EPPO A1 quarantine pest) to reproduce on eight weed species commonly found in corn and soybean fields in Iowa. The following weeds have been tested in glasshouse and in small plots in the field : Abutilon theophrasti (velvetleaf), Amaranthus retroflexus (redroot pigweed), Chenopodium album (lambsquarters), Cirsium arvense (Canada thistle), Helianthus annuus (wild sunflower), Setaria faberi (giant foxtail), Solanum ptycanthum (eastern black nightshade), Xanthium strumarium (cocklebur). The nematode population studied was H. glycines race 3. All tested weeds did not allow the reproduction of the nematode and can be considered as non-host of H. glycines.
