Integrated Pest Management Options

SCN is often confused with other common problems such as nutrient deficiencies, herbicide injury, soil compaction, drought, flodding or root rots. By the time above-ground symptoms from SCN feeding become noticeable, most fields have lost 25%-30% yield potential to the nematode. Early detection through scouting and soil testing is critical. If you suspect SCN, plants should be carefully dug (not pulled) and soil gently removed from the roots. Cysts are white to yellow and about the size of a pinhead. Rotating non-host crops such as corn, wheat, alfalfa or vegetable crops such as tomatoes, with resistant varieties, will lower SCN populations and improve yields on SCN-infested fields. In addition, rotation of SCN-resistant varieties is recommended to reduce shifts in the nematode population.
