Publication helps farmers understand how to check for soybean cyst nematode
Fall is always a good time for soil tests, and following the hot, dry summer of 2021, this is also a good time to test for soybean cyst nematode.
“Soybean cyst nematode, unfortunately, loves hot, dry soil so I am expecting higher than ever numbers from fall samples,” said Greg Tylka, professor in plant pathology and microbiology at Iowa State University.
SCN is a small, unsegmented plant-parasitic roundworm that attacks the roots of soybeans.
The nematode is the most economically significant pest of soybeans in Iowa and has been found in all 99 Iowa counties, according to Iowa State University Extension and Outreach. Infested soybean plants often show no symptoms other than reduced yield.
