Sampling Fields for SCN - 10/16/2014

Crisp, clear fall days are perfect for splitting firewood, tilling the garden under and collecting soil samples to check fields for the soybean cyst nematode (SCN). Although soil sampling for SCN might not be on most people’s list of favorite autumn chores, fall is a great time to sample fields for this pest. Reasons to sample for SCN include to check for the presence of the nematode in fields and to monitor SCN numbers in fields known to be infested with the pest.

Sample Fields for Soybean Cyst Nematode - 10/25/2013

As we work to complete harvest and put the finishing touches on the 2013 growing season, it is not too early to start thinking about 2014 crops. Results of soil samples collected in the next few weeks from fields in which soybeans will be grown in 2014 could mean the difference between “so-so” and profitable yields next year.

Plant-parasitic nematodes are microscopic worms that live in the soil and feed on plant roots. Nematodes that feed on corn occur in almost every field in Iowa, but most do not reduce corn yields measurably until they increase to high population densities (numbers). Fall is not a recommended time to check fields for damaging population densities of nematodes that feed on corn.
