Industrial oilseeds have a great potential in the northern Great Plains both as oilseeds and as cover crops sown following wheat (Triticum aestivum L.) harvest and before soybean [Glycine max (L.) Merr.] sowing in the following spring. One of the most important biotic stresses in soybean production is soybean cyst nematode (Heterodera glycines Ichinohe, SCN), a serious pest that affects 90% of the soybean producing areas in the U.S. The objective of this study was to evaluate the host status of and the SCN population reduction by, winter camelina [Camelina sativa (L.) Crantz, cv. Joelle], crambe (Crambe abyssinica Hochst. Ex R.E.Fr., cv. BelAnn), and brown mustard (Brassica juncea L. cv. Kodiak). The experiments were performed in a growth chamber at 27°C for 35 days by planting the crops in soil naturally infested with SCN and autoclaved sandy soil artificially inoculated with two SCN populations from two fields in North Dakota. Soybean cyst nematode did not reproduce on brown mustard or camelina with a female index (FI) of 0, suggesting these are non-hosts, while it reproduced on crambe. The numbers of white females on crambe ranged from 1 to 13 per plant with FI of 0.2 to 1.1 in naturally infested soils, and 1 to 4 per plant with FI of 1.2 to 2.5 in artificially infested soils, thus crambe would be classified as a poor-host (FI < 10). Brown mustard and winter camelina reduced the SCN populations by an average of 51% and 48%, respectively, while crambe only reduced the populations by an average of 24%, across all the experiments with naturally infested soils when compared with the initial population levels. Both brown mustard and camelina consistently reduced the SCN populations but crambe did not steadily reduce the SCN populations when compared with the non-planted control (fallow). Further understanding the effects of these crops on SCN populations under natural field conditions is needed to determine if cover crops can be used for sustainable SCN management in SCN-infested soybean fields.
