The plant pathogenic nematode Heterodera schachtii infects more than 200 different plants, including sugar beets, and causes significant economic losses. Over the past 50 years, the primary management tool in California has been crop rotation. When the number of H. schachtii in a soil exceeds a threshold, growers are contractually required by the local sugar factory to plant crops that do not support the nematode’s reproduction. This practice reduces the nematode population so that the next sugar beet crop can flourish.
