Soybean Cyst Nematode Survey in the Red River Valley
In 1954, the first detection of the soybean cyst nematode (SCN)
occurred in North Carolina. Since that time, the nematode has
become the most important disease issue of soybean in the world.
Spread with soil, this microscopic roundworm continues to gain
ground in Minnesota soybean-producing areas. Essentially anything
that can move small particles of soil will also transport this
nematode.

not on more than 30% of the plants.

desire to decrease risk tolerance and increase the use of
pesticides, this is not always a paying proposition.
