Soybean cyst nematode (SCN) is the most costly pest in U.S. soybeans today, routinely reducing yields in affected fields by 5 bushels or more per acre, according to the Crop Protection Network.

2011 Overview of Soybean Cyst Nematode Prepared in Jan 2011, reviewed in Oct 2024 Written by: Robert P. Mulrooney Extension Plant Pathologist Introduction The soybean cyst nematode (Heterodera ...

SCN’s insatiable appetite for soybean roots makes it the No. 1 yield-reducing soybean pest routinely causing more than $1.5 billion in annual losses. 1 Soybean cyst nematode claimed close to 90 ...

Oct. 2 is National Nematode Day and marks a good time to test fields for soybean cyst nematode, the No. 1 pathogen of soybean in the United States. “We anticipate the highest SCN levels to occur ...

Figure 1: Soybean field with visible symptoms of soybean cyst nematode damage. However, it’s important to know that SCN does not always cause visible symptoms and that up to 30% yield loss can ...

Cyst nematodes produce their effectors in their esophageal glands. In prior research, Baum's lab sequenced both the whole genome of the soybean cyst nematode and the transcriptome of its gland ...

Soybean cyst nematode, known as SCN, is a microscopic roundworm that infests the roots of soybeans, forming cysts that contain up to 500 eggs and the juvenile worms. The worms feed on the roots of the ...

The soybean cyst nematode, one of the crop's most destructive pests, isn't like most of its wormy relatives. Whereas the vast majority of nematodes look like the microscopic worms they are, the ...

The soybean cyst nematode (SCN) is the most damaging pathogen of soybean in the United States and Canada and it is spreading rapidly, according to information compiled by Gregory Tylka and ...

WASECA, Minn. — Soybean cyst nematode is found in most of Minnesota’s soybean growing region. Nematodes were most recently found in Becker and Clay counties. They were first discovered in the ...

The soybean cyst nematode causes a lot of costly damage. “Even a moderately low level of SCN is probably going to take two-to-five bushels per acre out of the yield,” Tylka says.
