This Memo helps you understand the challenges associated with cyst nematodes. We cover how to sample a field or area. Furthermore, we demonstrate how to submit samples for cyst analysis, how to interpret results and manage cyst nematode affected fields.
Cyst nematode numbers will be highest when the plants are almost mature until shortly after harvest.
For fields infested with Soybean Cyst Nematodes (H. glycines), run your samples before any SCN susceptible varieties are grown, or once a year if resistant varieties are grown in rotation. Sample Sugar Beet Cyst Nematodes (H. schachtii) injured fields once a year regardless of crop choice or insecticide/nematicide use.
