- If your populations come back as non-detectable (0) - and you have a good three-crop rotation (corn, wheat, soy) and you do not plant a double crop - sample for SCN every 20 years.
- If your populations come back as non-detectable (0) and you have wheat in your rotation but you double crop - sample for SCN every 10 years.
- If your populations are non-detectable (0) and you plant corn/soybean - sample every 10 years.
- If have SCN populations of 40 to 2,000 and you rotate corn/soybean/wheat, sample every five years.
- If SCN populations are 40 to 2,000 and you only plant soybeans, sample every year.
- If SCN populations have gotten out of control (>2,000) in the past, sample every year.
- Finally, fall is the best time to sample. It gives time for the labs to process them so you can make the best decision for choosing your variety for next year.
