This year, the laboratory has already seen unusually high Soybean Cyst Nematode (SCN) egg counts. Female nematodes started showing up in fields in early June, and in some cases, in as little as 26 days after planting.
Soil samples from the first week of June contained egg counts ranging from 1,100 to over 5,000. An early appearance could mean more generations of nematodes hatching this summer, resulting in higher populations and the potential for very high egg counts this fall.
Do you know if your fields are infested? Managing SCN can be difficult since no single tactic will control it, but determining the SCN population size and implementing management practices to control it can minimize yield loss and prevent further damage. To learn more about SCN, click here.
AgSource Laboratories offers SCN testing as an add-test to your annual/fall soil samples – no need for a separate sample. However, if you have a defined trouble area, it’s better to take a sample from that specific area. View our SCN example report.
Results will be reported as eggs per 100cc of soil.
