Recommended technique: Collect soil samples and have them tested for the presence of SCN.
When to sample
Fall is often the best time to sample as you plan for the next crop year. Sample as described below in the harvested field that is to be planted with soybeans next season.
Recommended technique: Collect soil samples and have the SCN population densities determined.
When to sample
You can take a soil sample to check on the progress of a SCN management plan at almost any time of the year. But if you want to monitor the effectiveness of your SCN management program over several years, you should sample at the same point in the management program each time (say after a year of resistant soybeans or nonhost crop).
Recommended technique: Collect soil samples and have them tested for the presence of SCN.
When to sample
Fall is often the best time to sample as you review harvest data. Take samples from the harvested soybean field, either in a zig-zag pattern or as part of a grid sample, as described below.
First, ask yourself - what is your purpose for scouting for SCN?
The answer to this question will help determine your best strategy— whether to check soybean roots or to collect a soil sample — and when and how to collect the sample.
