Questions about the Soybean Cyst Nematode Sampling Program in 2015

I have received many calls about the SCN sampling program in 2015.  I love the enthusiasm!  Below are answers to frequently answered questions.

Q.           How does the SCN sampling program work?

A.            The North Dakota Soybean Council will cover the cost of up to 2,000 SCN samples for growers in North Dakota.  NDSU will label and code SCN sample bags and distribute them to growers.  Growers take soil samples, bag them, mail into the lab and receive their results through the mail.

Q.           When will the sampling program begin?

A.            We will be distributing sample bags to County Extension offices in mid-late August, and at SCN field days in late August – early September. 

Q.           How do I receive sample bags?

A.            Each ND grower can get three bags by going to their County Extension office or attending a field day (tentatively located in Richland, Cass and Southern Traill Counties – dates TBD).  However, this is a first-come first-serve program.

Q.           When is the best time to sample?

A.            The number of eggs and cysts in the soil increase throughout the growing season, making SCN detection most likely if you sample at the end of the season.  Sampling from just before harvest to just before freeze-up is generally recommended. 

Q.           What do the results tell me?

A.            Essentially, results will tell you if have SCN or not.  If you have SCN, you will want to actively manage it; resistance, rotation and maybe seed treatments.  If you don’t have it, be happy, and test again in coming years.
