Fall: The best time to sample soil for soybean cyst nematode

Soybean harvest is nearing as most, if not all, soybeans have turned color or dropped leaves.

Fall time is the best time of year to sample and test the soil for soybean cyst nematode, the number one silent yield robber of soybean.

Soybean cyst nematode is estimated to cause over $1 billion annually in the U.S. soybean crop. As of 2017, SCN has been detected in 30 counties in South Dakota.

Some fields have been found to have very high SCN population densities (>60,000 eggs per 100 cc of soil) and therefore the yield loss caused by SCN in such fields is high. READ MORE
