The sugarbeet cyst nematode (Heterodera schachtii) was first discovered in 1859 in Germany infecting sugar beet plants. It can infect over 200 plant species including sugar beet, radishes, broccoli and cabbage. The nematode survives in soil as cysts containing eggs and juveniles. When conditions are favorable, juveniles hatch and infect root tissue, developing into adults. The female remains in the root while producing 200-300 eggs. Upon death, her body hardens into a cyst protecting the eggs. Management includes crop rotation, planting resistant varieties, and controlling weeds that are hosts.
